You will be making a hypothesis in order to predict how the design modification you make to your glider (increasing lift, increasing lift + drag, decreasing lift, or increasing drag + weight) will affect your dependent variable (distance the glider travels, or distance the glider lands from a target). As we have learned from a year of spectacular science, we need background research (evidence) in order to make a hypothesis (tentative claim).
You may use Shonscience posts, videos, and articles (including those from Mr. Cirone's class) to conduct your background research. Below are links to articles that will support your research. The key is find supporting evidence that addresses the question, "How will your independent variable affect your dependent variable?"

Assignment
Read the blog post above, watch the videos, and explore the interactive websites (links). Then answer the questions below. Make sure to write the question and answer in complete sentences to receive full credit. There is an extra credit opportunity below! Due Monday, June 9, 2014 Part I & II 1. What type of plane motion (roll, pitch, or yaw) occurs when a plane takes off and lands? 2. What type of plane motion (roll, pitch, or yaw) occurs when a plane makes a left or right turn in the air? 3. Where are the ailerons of a plane located? 4. What is the function of the ailerons? 5. Where is the elevator of the plane located? 6. What is the function of the elevator (on a plane)? 7. Where are the rudders of a plane located? 8. What is the function of the rudders? Part III 1. What is camber? 2. What is the difference between upper camber and lower camber? 3. A high-speed, low-lift airfoil has very __________________ camber. 4. A low-speed, high-lift airfoil, like that on the Cessna 150, has a very ________________ camber. 5. Sketch the upper and lower camber line of an airfoil. Part IV: Explore the website on wing design and answer the questions that follow: http://www.pbs.org/wgbh/nova/space/lift-drag.html 1. What two forces combine to create lift? 2. An airfoil also creates lift by __________________ or redirecting airflow. 3. The amount of drag depends on an object's _________________ and _____________. 4. What will have more drag: a) monster truck; b) sports car 5. A __________________ surface causes more drag than a smooth, polished one. 6. A fighter jet has low lift and low drag. What about its wing shape gives it these properties? 7. How does the airfoil of the crop duster compare to the wing of the fighter jet? Extra Credit: Click on the link below to find the best lift to drag ratio (L/D) for different planes by adjusting their angle of attack and air speed. Then answer the questions below. http://howthingsfly.si.edu/activities/how-wings-work 1. Why do you think a higher lift to drag ratio (L/D) is a major goal in wing design? 2. In order to achieve the best lift to drag ratio (L/D) for the Bleriot airfoil, what is the angle of attack and airspeed needed? 3. In order to achieve the best lift to drag ratio (L/D) for the DC-3 airfoil, what is the angle of attack and airspeed needed? 4. In order to achieve the best lift to drag ratio (L/D) for the 757 airfoil, what is the angle of attack and airspeed needed? When the forces of flight are balanced, an object can fly in a level direction. An object can go up (take-off!) if the forces of lift and thrust are more than weight and drag . An object can go down (land!) if the forces of weight and drag are greater than lift and thrust. How do objects DEFY gravity? In other words, how can we create the lift needed to overcome weight (the force of gravity)? Lift can overcome weight in two ways: 1) By creating differences in air pressure. 2) By pushing air downward. But what does this even mean?!?!?! There there. I'll explain.
So now we have Lift. Where do we get Thrust? That's a much easier explanation. We get thrust from engines (like a car), propellers, and rockets! Still confused? Watch the Bill Nye + BrainPop videos on flight (videos + links below)! Assignment Answer the questions below in complete sentences, using the blog post, videos, and class notes to help you. WRITE the question and answer. Due: Friday, June 6, 2014 1. What are the four forces of flight?
2. How does a plane balance the forces of flight in order to land safely? (hint: some forces must overcome others) 3. What is an airfoil? 4. Sketch an airfoil. 5. What is Bernoulli's principle? 6. How does Bernoulli's principle relate to flight? 7. What is another example of Bernoulli's principle in the real world? (hint: there is a poster in Ms. Shon's classroom with examples) 8. What is Newton's 3rd Law? 9. How does Newton's 3rd Law of motion relate to flight? 10. What is another example of Newton's 3rd Law of motion in the real world? |
