Rebecca's Group's Turbine

Table

Questions:

1) Our rotors made out of playing cards worked better than our ones made out of feathers. The reason for this is because the cards were sturdier and so held wind/air pressure better to cause it to turn without bending or letting air pass through. Therefore, our playing card rotors produced more power than the feathers.

2) Max output difference (spreadsheet) between ours and top

3) Our card model had some limitations. First limitation was that it was short so it couldn't reach out far and capture more wind or pressure to allow it to move better and faster with more strength. Another problem was that we couldn't curve the rotors to allow them to cup the wind better.

4) How do an airplane and windmill use pressure to fly and rotate?An airplane uses pressure to fly. To do this, it gathers a lot of speed using Bernoulli's principle of an increase in speed of a fluid decreases pressure. In saying this, the faster a plane goes the less pressure there is keeping it down allowing it to rise up with little resistance. The windmill uses pressure to rotate by having it press against its rotors not just to glance off but to force movement and create a rotation.

5) The rotors had to be tilted in order to catch the wind. If the rotors were to remain straightir pressure and force of wind would just slide right over and off. Because of the tilt, part of the pressure was captured and able to turn the blades.

6) The rotors of a windmill and sails of a sailboat are similar in using the same principal as they both use wind and air pressure to move and operate. Wind is captured on rotors to create a thrust to move the rotors in a circular motion to create energy. Sails take the wind and use it to thrust up against it allowing the force to move the object forward. So, they both use pressure to move. 

Windmill Questions

1)Which rotor had the most power and why?
The rotor that worked the best was the one that was made out if milk jug, we got it to work then it didn't work at all when we added weights, so we tried bending the wings all in the same directions a it worked great!
2)What was different about the design with the most out put?



3)What are the limitations of the model?
The limitations are that the milk jug was flimsy and kinda moved, also it didn't catch a ton of wind it caught enough

• Which rotor has the most power? Why? The second one because it was wasn't too light and wasn't too heavy.
• What was the different  from the design with the most output? It had longer wings.
• What are the limitations to the model? We could've made it bigger and maybe try to get more weights to be lifted.
• How do airplanes and windmills compare? They use their wings to move.
• Why did we twist the rotor blades at an angel to grab the wind? So that it would spin easier and faster.
• Explain how windmills and sailboats use the sane principles. When the wind hits from a distance it seems to move faster, you don't want to be right up close to the windmills and sailboats because it will slow it down or won't even move at all.

Our Turbine that had the most power was our small one made out of cut up pop cans with a small dowel. It had the most power by default. The other didn't work. Ours was short and thin, looked like it could have been a scale model. The limitations of our model were that it wasn't heavy enough to support itself, and slid around. The other just wasn't glued well and had a smaller blade than the others. Airplanes and Windmills work by a change in air pressure. Airplanes also have small blades that come off of the end that catch the wind at a proper angle to cause lift. That same property can be applied to windmills. It has a slant on one side of the blade, which allows it to catch wind and not lose a lot of air. That is why it is necessary to have the rotor blades at an angle. The sail on a sailboat is long and thin, just like a successful rotor. It also has a slight angle, and catches the wind. On the correct angle, it is caught by the wind and moves, just as a windmill catches the wind and spins.

Paper (test 2)	85 cm	13.77 grams	12 seconds	114.94 joules	9.578 watts

1.) Our paper rotor had the most output because the rotor was more reliable when it was spinning. It didn't stop and start as much as the other one so it gained more momentum.

2.) The paper rotor had more surface area and a greater angle on the blades.

3.) Some limitations to our rotor are that the blades are not very long so they won't be able to use as much air to spin.

4.) When the wind hits the edge of the blade, it splits the wind in two. One way goes above and has no effect. The other goes down and gets pushed down by the angle of the wing. The wind then pushes the plane up. The same basic effect goes for the windmills.

5.) It is necessary to twist the rotor blades in order for it to be able to catch and redirect the airflow to one side in order for it to spin.

6.) The rotors of a windmill and the sail on a sail boat both catch the air in order to move. The rotor moves the air to one side to spin and the sail catches the wind and holds it to move straight forward.

1. The one of our windmills that worked the best was the playing card version (as opposed to the turkey feather version). Both of the turbines were built with a base of foam and had three blades in the foam at an angle. However, the playing card blades caught the wind better than the feather blades did. This was because the cards were uniform,rigid, and held their shape while the feathers varied in size, were easily broken, and were more flimsy. The design worked both times, but the cards were a lightweight and sturdy material, proving more efficient than the feathers.

2. The one of our classes that worked the best was the one that Miranda and Kelsey made(16.69 w). However, they did not have a picture, so I'm not sure why it worked better. The second best was made by Nate, Mike, and Evan, (10.03 w) but they also didn't have a picture. The third best was made by Jacob and Tyler(9.85w) who also didn't have a picture. (I'm sensing a pattern here.) The fourth best was made by Sofia, Jessica, and Samantha (6.5 w). Luckily, they did have a picture. Their design included slightly cupped blades that were taped to the dowel using masking tape. The blades were about six inches long and three or four inches tall. I think that the reason theirs worked better than ours was because their blades, made of cardboard, were sturdier and heavier than ours. They were all of a uniform size, kept their shape, and caught the wind easily. They were attached to the dowel in a sturdy way and were able to turn and lift weight.
3. Some limitations on our model were the size, design, and materials. Since we used playing cards and feathers for our blades, they weren't able to lift much due to their light weight. Our blades were also rather short; longer blades output more energy. The feathers especially were somewhat flimsy. Due to the work we did with them, they began to tear and not catch the wind as well. We used foam to hold the blades in place, which was not the firmest. The blades were also not all at the exact same angle of tilt, making them less efficient. The playing cards did not have any curve in them, and were only tilted, making them less aerodynamic and less functional. Since the blades were not all uniform (mainly the feathers) the wind did not catch them all the same. It would have worked better to have slightly stronger and better attached blades that were all uniform, longer, and more curved.

4. Both airplanes and windmills are affected by Bernoulli's Principle: as velocity of a fluid increases, pressure decreases. Airplanes use this change in pressure to fly; as they go faster, there is less pressure above the plane and more beneath it, creating lift so they can stay in the air. As a windmill begins to turn faster, there is less pressure beneath the blades and more above them, causing it to continue the turning motion. Much of this is due to curvature and tilting of the blades/wings, since the wind moves faster over a curved surface.

5. It is necessary to twist the rotor blades at an angle so they can catch the wind. If you have flat blades, wind blown on them will just be stopped. If the blades are at an angle, they have the opportunity to catch the wind and turn, giving off energy. Rounded or cupped blades also don't work, since the wind will fill up the blade and not move anything; tilted blades catch and spin.

6. Rotors on a windmill and the sail of a sailboat are both designed to catch the wind and move forward. A sail is tilted so when the wind catches it, the boat is moved in that direction. The blades of a windmill are tilted to catch the wind and turn in that direction. The tilt and turning factors show how windmills and sailboats operate on the same principle.

Rotor Questions

Results
Mass Height Time Energy Power
8.84g .13m 76 sec 11.29 .15 watts

Which rotor had the most power? Why?

We only had one rotor because it was dropped and broke and we didn't have enough time to make another. It didn't work because it short and wide rather than long and thin. Also, one blade was heavier than the others.

What was different about the design with the most output?

Our design was different from others because it was made from aluminum pop cans. Most of the other designs were cardboard. Ours was also a lot smaller than the other windmills.

What are some limitations of your design?

One limitation of our design is the weight. The windmill was very small and lightweight. One of the blades was heavier than the others too so it when it got to the bottom it would stop rotating.

Another limitation is the blade angle. The blades were not twisted so the wind just ran into the blade without turning it.

How do an airplane and a windmill use air pressure to fly and rotate?

The sail of a windmill and the blade of a windmill are a lot alike. They both use a twisted shape. This makes the air push on it and create a change in air pressure which causes the windmill to turn and the sail to carry the boat with it.

Why do you have to twist the blades on the windmill?

Twisting the blades makes the air push off it. Without twisting the blades, the wind just runs into the blade without pushing the blade.

How does a windmill rotor and a sailboat have the same principle?

They both use air pressure to move by being pushed by wind.

Wind Turbines

1. Which windmill had the most power? Our purple windmill had more power because the wings let the air to push them around.

2. What was different about the design with the most power? The blades in the less affective one didn't have enough space in them to make the wind hit it and make the turbine turn. In the one that worked, the rotors were cupped, which allowed the air to go in and hit the side, making it turn.

3. What are the limitations of the model?

One of the limitations was the blades were too caved in and air would get trapped in, sometimes causing the windmill to slow down. We also could have tilted the blades a little bit more and make them longer so the air would pass through more easily.

4. How do airplanes and windmills use air pressure to fly or rotate? The blades are set at an angle and have a curve to them so that the air pressure pushes them.

5. Why is it necessary to twist the rotor blades at an angle? So that the air doesn't hit the blade evenly, because then it wont be able to push and put pressure on it and it wont rotate.

6.  Explain how the rotors of a windmill and sailboat illustrate the same principle? They both use Burnellies principle because the blades have a curve in them.

Wind Turbines

1. Which rotor had the most power and why?
My 3 bladed turbine worked the best.  It worked best because it had more wings to catch the wind and create more power.
2. What is the difference in the design that had the most outout?
 The wind turbine that had the most output had long and skinny blades. My blades were short and fat.
3. What are the limitations to your model?
My blades were short and fat so they lost alot of energy and did not catch as much wind as the others.
4. How do an airplane and windmill use air pressure to fly and rotate?
Both blades have a angle to them that when the wind catches the curve it creates lift.
5. Why was it necessary to twist the rotor blades at an angle?
So that the blades can catch the wind and make them move.
6. Explain how the rotors on a windmill and the sail of a sailboat illustrate the same principle?
The blades and sail both have a curve/ angle to it so that it can catch the wind.  They both use lift to move.

Windmills

1. Which roder had the most power and why?- The purple roder with four sides had the most power because it had more room for the wind to hit it and push it. 2. What was different about the design that had the most output?- it was shorter but wide on the inside. It had more space for the wind to go in and push it. 3. What are the limitations or model?- the model is roud and deep inside. Some limitations of our windmill are we could made the windmill longer instead of it being short. 4. How does an airplain and a windmill use pressure to fly?- a windmill has a smooth but roudish figure when the wind hits the widmill the wind will go smoothly over the mill and get caught in the curves which pushes it around. 5. Why is it necessary to twist the roder blades at an angle?- so the wind can fly smoothly over and around the windmill while still pushing the windmill. 6. Explain how roders of a windmill and the sail of a sailboat have the same principle.- They bothe are tilted to catch the wind to make the objects move. Power of our windmill- 6.5 High Energy- 69.96 Mass- 7.5 Time- 41 sec.

Windmill Questions

1. Which rotor had the most power and why?
The rotor that worked the best for us was our one made out of milk jugs.  It worked well because it was a hard plastic and had the curves so that the wind hit it just right to get it to move.  Our other one didn't have the bend and didn't move as well.
2.What was different about the design with the most out put?
I noticed that the designs that worked the best were long and slender compared to our design. I think that that probably helped it catch the wind better.
3.What are the limitations of the model?
Looking at the other models I would say that a limitation of ours is that it was not as long and skinny as the ones that worked well.
4.How do airplanes and windmill use air pressure to rotate. 
If you look closely the wings on a plane and on a windmill have a slight curve in the wing.  This helps so that when the air pressure hits it the wind will flow right over the wing causing it to spin/lift the wing.
5.Why was it necessary to twist the blades?
By twisting the blades all the same direction the air pressure will hit them just right making the air go over the blade which causes it to spin.
6.How do rotors of a windmill and the sail of a sailboat illustrate the same principles?
They illustrate the same principle because they both have slight curves in the sail/wing that cause the air pressure to hit it and go over it causing it to move.

Windmills

1.I made two rotors and the only difference was how they were connected to the dowel. One was connected by three vertically slanted craft sticks on the dowel, the other was three craft sticks connected to two pyramids that surrounded the dowel. The one with the two pyramids had a shorter base then the three craft sticks directly connected to the dowel, since I had cut the craft sticks. The pyramid windmill worked better, probably because it had more room for the string to move by itself, which meant I had to touch it (and cause friction) less often.
2.The difference between most of the turbines and the most powerful one was that the most powerful one had long and thin turbines and most of the others were short and wide. The most powerful one also looked like it had sturdy turbines, unlike the other turbines that were long and thin, which looked flexible. If the turbines were flexible, the wind wouldn't be able to apply as much pressure.
3.Some limitations to my design could be that the turbines aren't slanted. Because of the turbines not being slanted very much, the wind hit the turbines at an equal force, not allowing for rotation to happen. Also, with my triangle rotor, I think one of my turbines was heavier then the others, so that it wasn't able to spin easily.
4.An airplane uses air pressure by making the wind going over the top of the wing go faster then the wind going under the wing, causing lift and pushing up on the wings, which lifts the airplane into the sky. A turbine uses air pressure by having the air pressure slide by the slanted wing, which means when the air pushes off to one side so that the air can continue it's forward momentum. When the air does this, it pushes on the wing so that the wing spins in the other direction, causing rotation.
5.It is necessary to put the turbine wings at a slant so that the air doesn't evenly hit the wings, because if the air hit the wings evenly, there would be no rotation.
6.A turbine and a sail on a sailboat both use air pressure to push the sail or wing forward. When a sail is used going with the wind, the wind is pushing against the sail, which moves it forward. When the sailboat is going against the wind, what happens is the sail goes at a back and forth slant. When the sail is at a slant, an area of low pressure is made at the front side of the sail because of the wind going to the back of the sail, according to Newton's Third Law. This creates an opposite push. This happens with a wind turbine also.

Wind

What Are The Limitations Of The Model?
My model could hold three weights which is equil to 22.31 grams. When I added the fourth weight it couldnt quite spin all the way. The blades would slightly turn but could not completely go around. My model could also only spin with three weights if the fan was on high. Without that amount of wind my model failed to spin fluently.
How Do An Airplane And A Windmeal Use Air To Rotate?
They both have an air foil that creates pressure causing rotation within the blades.
Why Was It Necessary To Twist The Rodar Blades At An Angle?
Twisting the blades allowed it to have a resistance against the wind or the air flow. When there is resistance it helps the blades rotate with the wind direction.

Wind

Which Rotor Had More Power?

I was told to test just one of mine due to time issues, but the one that was tested was made out of poster board cut into four blades that each intersect eachother. At the ends of each blade is a cup like figure to help catch the wind drifting from the fan.

Why Was It Necasary To Twist The Rotor Blades at an Angle?

Twisting the blades helped them move with the wind or to help it catch wind without it like this, its likely that it wont spin.

Explain How The Rotors On a Wind Windmill and The Sail of a Sailboat Illistrate The Same Principle.

Withput a sail on a sailboat it wouldnt be able o move as fast, it would only be able to move by the push of the waves. When the wind catches the sail or a blade catches the wind it helps push forward or backwards depending on the set up of the wind and the sail.

• I learned that cancer cells don't stop growing and that is how they create tumors.
• Other cells in the body don't know hat the cancer cells are bad so they don't kill them.
• Alcohal and other things can increase the chance of geting cancer.
• Chemotherapy doesn't just kill cancer cells in also kills some good cells in your body. That is why you get weak and lose your hair.
• If your family has a history of cancer you have 50% chance of geting cancer.
• Is there water that can cause cancer?
• Is there a posability that plants can get the same type of cancer?
• I like the fact that there is such thing as a tumor that doesn't grow called benine.
• I dislike the fact that chemotherapy kills other cells in your body other than the cancer.

What I've learned..

What I have learned through out this unit about cancer, is that malignant mean cancerous, and benign means non cancerous, I have also learn a lot about many different cancers like; Lung Cancer, Colon Cancer, Skin Cancer, an that's just a few. Also I learnd that metastasis mean the spreading from one area of the body to another, for example If you have lung cancer that is in you lungs there is a chance of it moving from your lungs to another area of the body. Another thing I have learned was that everybody has cancer cells in them, and that you family history and diet can effect the risk factor for cancer. Some of the thing in this unit that I liked a lot were the assignment of 1 cancer to research, and getting to work with my classmates. Some of the things that I didn't like were the assignments of certain jobs for your cancer, because it was very easy to get your mixed up with other peoples and when we where presenting I believe it confused the audience because when I was listening to other groups I was getting lost. A couple of questions that I didn't get answered were Q: what makes different cancers differnent than one another? And Q: how can a healthy diet make your chances of cancer decrease? I really enjoyed this unit I felt like I knew exactly what was going on all the time!!

Jessica's cancer project

1. Metastasis~when cancer spreads from oe part of the body to another
2. Tumor~ when tissue cells grow uncontrolably
3. Processed products are not good for you when you have breast cancer
~processed like canned stuff such as meat, vegetables, and fruits
4. Chemotherapy can cause you to gain weight and being over weight doesn't help with cancer
5. Some kinds of breast cancers can look like spider bites and it can be hard to detect



1-2 questions I still want to learn about breast cancer
1. should kids ages between 12-18 be worried about getting breast

1 thing I liked- it was nice learning about what has killed alot of people
1 thing I didn't like- breast cancer killes alot of people

Cancer

• 5 of the things I learned about cancer this unit are:

1. You get cancer when cell division goes wrong. If the chromosomes don't divide equally, the cell still keeps going, but at a faster rate and keeps going without stopping. Eventually, you get a lot of cells packing up on top of each other, that turns into a tumor.
2. Not all tumors are cancerous, they're called benign. If they are cancerous then you call it malignant.
3. When cancer spreads throughout the whole body its called Metastasis. By then you're in a advanced stage.
4. There is a type of cancer called Inflammatory Breast Cancer. At first it looks like a spider bite, and most people don't really pay attention, but when it keeps growing they finally do. By then its usually too late and the person who had it dies very soon.(sometimes in 3 weeks) A girl as young as the age 12 died from this type of cancer.
5. A lot of times you get a higher risk of a type of cancer depending on what your nationality is. (EX. If you're an African American, you have a higher chance of getting Prostate Cancer than other nationalities.

• 2 Questions that were not answered: 

1. If they found a cure for the cancer, why don't they use it now?
2. Is it worse to go tanning outside or fake-baking?

•  I liked how we did the project with individual jobs. It gave a chance to fully understand what we were learning about and do more research. I also liked how we got to choose a type of cancer on our own in the individual research. It made it more interesting because we wanted to know specifically about that type.

• One thing that I didn't like was that we got a little bit of time to do the group project, worksheet, AND individual cancer research. It made things a bit stressful.

• I learned that not all tumors are cancerous when it is cancerous is is called malignet and when its not is in benin.
• I learned that meiosis produces four sex cells.
• I learned that females can only use one out of the four cells produced by meiosis.
• I learned that cancer is the rapid production of aq cell that is bad or a cell that either skipped a step in the cell cycle or something went wrong in the cycle.
• I learned that meiosis creates different combinations of our chromsomes so no two cells are alike once they have gone through meiosis.
• what is the body mass index?
• I liked mostly everything about this project
• the only thing that i didnt like was having to use the slow computers.

During our cancer unit I learned several new things. I learned that not all tumors are cancerous. If a tumor is cancerous, then it's malignant; if it's not, then it's benign. I also learned those terms to describe the type of tumor it is. Another new thing I discovered is that there is a gene in cells called P53 and when this particular gene has a mutation, it leads to cancer. It affects the checkpoints in cells which where the cell pauses in the cell cycle to make sure there are no problems. Whenever there is, the cell automatically will either fix any problems or mutations or else kill itself. When the P53 is defective, these checkpoints don't occur or work. Also I learned what carcinogens are. Carcinogens are cancer causing chemicals. Cancer typically is not completely fatal or horrible or terribly painful until it reaches a stage it can proceed with metastasis. Metastasis is the last newly learned thing I will explain although I learned more than this. Metastasis is a process where cancer cells travel through blood vessels to other locations in the body. They then attach themselves to the walls of the vessels and eventually make their way through the wall into the tissue of an organ and continue reproducing more cancer cells there. That is how cancer spreads to other areas of the body and gets worse. One thing that I really liked about this unit was how we all got to act as specialists to diagnose a pretend patient. We had to evaluate the symptoms and problems our patients were having and do research to decide what possible cancers they might have and what tests to recommend they take to find out. Once the cancer was confirmed we all had our own jobs to do to help treat the patient or educate the patient on how to help themselves and explain everything that was happening to them. It was a great experience to act as though we were part of something like that and know what all happens and get a feel for how it works. I'm confident that I know a lot more about cancer now and what it actually means to have cancer. Something that I didn't like as much about this unit was there were times when I felt it was a little too independent. We got help if we ever asked, but I personally didn't feel completely confident about what I was doing. There's no one else in the class who has the same cancer as your small group but no one in your group has the same job as you. On top of all the other classes we have and the work we do for them, I guess it just felt overwhelming. Over all it was still an enlightening experience that was well worth it. Now that the unit is over, I still have a few questions: What is all being done to find better treatments for cancer? How much time, energy, and money is being put into research? Besides donating money to random cancer fundraisers, what can I do to help any part of the cancer situation personally? What are the chances of me or any of my friends getting cancer? How many people in the world are estimated to be affected directly by cancer? There's still a lot left to answer.

Cancer Nate Sams 2/2/12

During our cancer unit i learned about how a tumor can be malignant, cancerous, and benign, not cancerous. Also, I learned that family history can play a large role in whether or not you can get most types of cancers. There is also a chance of getting cancer on your lifestyle choices like whether you smoke or drink alcohol, you can get cancer by being overweight for cancers like prostate, and pancreatic. Lastly I learned that metastasis is how cancer spreads throughout the body. 2 questions that were unanswered during the unit were when the cancer spreads is there a certain place each kinds of cancer attaches like when breast cancer spreads does it go to a specific other part of the body? My other question was what kinds of cancer can infants get. 1 thing that i enjoyed during the unit was the independent study of a cancer of our choice. What I disliked was the webquest.

Cancer

This is what I learned about cancer as a result of our projects. I did not know that males could get breast cancer. I didn't know that Asians were the least likely to get melanoma. I learned about what mascectomies and lumpectomies were, and the differences of both. I also didn't know that cancer was capable of moving into the bloodstream and traveling to other parts of the body. This is called metastasis. I didn't know what carcinogens were, either. They're cancer-causing agents. Here are a couple questions I still have about cancer. How many people in the world are estimated to have some type of cancer? What is a male's chance of getting breast cancer? What I liked about this project was the fact that we didn't have an outline that told us exactly what to do. We had very general instructions and we weren't walked through everything. What I didn't like about this project was the lack of time we were given to complete it.

Cancer Project

5 of the thinks i learned while doing this project are:

• That not all tumors are cancerous. Sometimes normal cells can grow but they aren't cancerous.
• The words benign and malignant and there meanings. Benign means a noncanerous tumor, malignant means a cancerous tumor.
• How the cancer can spread throughout the body by getting into the blood stream.
• What radiation therapy is and how it works.
• What triggeres cancer to grow and how your lifestyle can effect you.

2 questions that i have are:

• Can you or do you have to get noncancerous tumor removed?
• Can you get a cancerous tumor on top of a noncancerous tumor?

I am interested in becoming a pharmacist or something in the medical field so i really enjoyed my job as the Pharmacologist.

One think i didn't like about this project is finding out that everything we do basically can trigger cancer cells in our body to react.  

Cancer

5 Things I Learned

1. Cancers have stages
2. Metastasis is when the cancer spreads to other parts of the body
3. Not all tumors are cancerous
4. Normal cells can form into cancer cells
5. Benign is a non-cancerous tumor and malignant is a cancerous tumor

I liked that we were given a patient and a specific job. I learned more this way then I would have taking notes. I also liked that we worked in groups, but we got graded on what we did and not by what our group did.

I did not like that the project was due in such a short time.

1-2 Questions

Do all cancers run in the family?

Did all the patients survive their treatments?

Cancer

Five things I learned about cancer:
     1.) Cancer cells form from regular cells.
     2.) Cancer isn't confined to one area of the body at a time; it can travel. (metastasis)
     3.) Not all tumors are cancerous. The the difference is whether they are benign or malignant.
     4.) Cancer usually comes from a persons choice to live an unhealthy life. (junk food, lazy, smoking, etc.)
     5.) The immune system can't help fight cancer.

Two questions that I still have about cancer are:
     1.) Can cancer occur in every organ in the human body? (i.e. the eye)
     2.) Can injuries/stress cause cancer?

One thing I liked about the cancer unit is I learned a lot about how cancer forms and progresses.

One thing I disliked about the cancer unit is we had to work in teams that we weren't able to choose.

The five things I have learned from our cancer project/webquest are:

1. There are more than just cancer tumor. If its Malignant, it is cancerous, if its benign, its not cancerous.




2. When you have cancer, you can't necessarily just remove it, you have to treat it. If its benign, then you can just remove it.




3. I learned that Chemotherapy is more than just a common cancer treatment that makes you sick. You have to take an oral medication that kills both healthy cells and cancerous cells.


4. I learned what metastasis is. Its when the cancerous cells spread from areas apart from where the inital cancer started.


5. The final thing I learned is that if you are battling cancer, you will be in a much better position if you stay active and make sure you eat healthy. If you eat fatty foods, your body won't be strong enough to fight the cancer off.

One question of mine that wasn't answered was why cancer can be so deadly. Its only a bunch of cells gone wrong. Can't you just remove them and let your body continue mitosis with healthy cells? I guess I just don't get it.

I liked that we could learn about cancer a little more in depth, because all I really knew about it prior to the lesson was that it took many lives every year, and that depending on the cancer, there are a lot of people diagnosed with the many types of cancer.

I didn't like the fact that we had to present it all to the class in a group. Because when we got to the test, our pharmocologist hadn't done his job, so I didn't know too much about what treatment could be done or what the specific side effects were.

I learned five things from this cancer project that we did, and they are

1. There are two diffrent types of tumors benign which means the tumor is noncancerous and malignant which means the tumor is cancerous.



2. When you have cancer, you cna't necessarily just remove it, you have to treat it. If its beingn, then you can just remove it.



3. Metastasis is when the cancer travles to another place in your body.



4. The treatment chemotherapy is for almost anytype of cancer.



5. The immune system helps to fight cancer

Two questions that weren't answered are:

1. Can someone get lung cancer from only smoking.
2. What are the two most popular cancers that people get

One thing I liked/disliked

Liked: working in groups

Disliked: presenting

After researching cancer for a science project, I learned a lot about cancer and some facts that are important to know. Things I learned:
Metastasis is when cancer starts spreading to other parts of the body. It spreads by shedding of cancer cells off of a tumor or catches on to lymph-nodes which take it to other places. There is many other ways it spreads also.
There are cancer tumors and non-cancer tumors. Non-cancer tumors are known as benign. Cancerous tumors are called malignant tumors.
Many cancers such as prostate and pancreatic cancer, do not show symptoms until they are in an advanced stage. This means it is important to get regular check ups with your doctor and have certain tests done to check for cancer.
One common type of therapy to treat cancer is chemoradiation. I knew there was chemotherapy and radiation but I didn't know they could mix the two. It is where they give you chemotherapy either before or after radiation. This gets rid of cancer that was missed or make it easier for surgery.
Eating a colorful diet helps reduce your risk of cancer. This means eat lots of fruits and vegetables and stay away from pop.

One question I could not find the answer to is the survival rate after chemoradiation for pancreatic cancer. There was no certain percentage or number that I found.

The thing I liked most about researching cancer is I learned the symptoms of different types of cancer, what causes cancer, and what helps reduce a person's risk of cancer. Now I am aware of all of this and know how to stay healthy and identify cancer if symptoms ever show up.

Something I didn't like about the cancer project is it took a lot more thinking than most projects I have done in the past. I had to research a lot harder and know what everything I said meant. This was good because I learned more but I didn't like it because it took more work and thought.

Five things I learned

• Tumors are not Cancerous.
  
• There are many stages in cancer and once you get to the last stage there are no treatments that can help heal you or fight the cancer.
• Sodium nitrite is salt in preservatives ingredients(cold cuts)
• BMI means Body Mass Index
• That race is a risk factor to getting some types of cancer(Skin Cancer and Prostate Cancer)

1-2 Questions not answered

• If You have a tumor and you die from it, wouldn't that be cancerous? Or no?
• Radiations of electronics, are they risking our chances of getting cancer in the future?

1 thing I liked

• I liked how we were assigned a patient and were told to learn about them. We were given jobs. I learned more this way and how being healthy plays a big role in staying a live.

1 thing I didn't like

• The Webquest.

During this cancer unit, I learned a number of things about cancer. One was how cancer forms. I never really knew that it was a genetic mutation that caused cancer. As it turns out, the cause of cancer starts with the genes inside and not so much with the factors outside. Another thing I learned was how cancer spreads. I knew cancer could spread, but I found out that the process is called metastasis and happens in a way I hadn't thought of. The cancerous cells get into the blood stream and travel to other parts of the body. Somewhere along this journey, the attach to the wall of a blood vessel and make their way out into the surrounding tissues. This is how cancer can spread so quickly. I also found out that not all tumors are cancerous. When you get a tumor, it can be either malignant or benign. After a tumor is examined by a doctor, it can be named cancerous (malignant) or safe (benign). Having a tumor does not necessarily mean having cancer. The P53 gene was also new to me. Cancer forms due to a mutation on one of the many genes. However, mutations on the P53 gene are more likely to cause cancer than some other mutations. Problems with this gene can lead to cells not following the proper check points in the cell cycle. Another new thing to me was carcinogens. I had heard the word before, but I didn't know what it meant or what things would be concidered carcinogens. Carcinogens are chemicals that are linked to causing cancer. A lot of commonly seen things can be carcinogens such as asbestos, smoke, even some brands of chewing gum. This was one of the most important things I learned: cancer can be caused by a lot of simple things; you really need to watch your lifestyle.

Though this project answered most of my questions about cancer, it still left me wondering about some things. I still don't know how exactly genes mutate to form cancer or which genes mutated for which specific cancers. Granted, some cancers are still being researched and this information hasn't been found yet. Still, it would have been nice to know how the mutations happen. It also wasn't explained how certain foods or substances help your body fight off cancer; what they contained and how they fought off the disease.

I liked a lot of things about this project. What really clicked for me was the connection to real life. You were given a "patient" with a normal life that you had to diagnose with cancer. Seeing the different types of people that were all susceptible to the disease was really interesting. You learned the material, but you had something familiar to connect it to.

During this project, I didn't like the fact that we also had to do a webquest along with the specific cancer patient. It took some time away from working on the presentation. However, I really don't have anything else bad to say about this project. I enjoyed learning more about cancer, since I've heard so much about it.
