8.  Question: What is a system? What are the parts of a model plane system?  Hypothesis: Hypothesize and share. Exploring Flight

9.  Plan: Student Sheet 12 Exploring Flight

10. 1. Use sandpaper to taper both ends of both craft sticks on one side. They should fit this outline. Exploring Flight

11. 2. Cut the super jumbo (red and white) straw in half. Punch one hole in each half near the end. Slide the jumbo (clear) straw through the holes. Exploring Flight

12. 3. Flatten the free ends of both super jumbo (red and white) straws. Use a craft stick. Exploring Flight

13. 4. Trap the flattened ends of the two super jumbos between the two tapered craft sticks. Make sure the tapered edge is up. Slide the propeller on one end and the hook on the other. Exploring Flight

14. 5. Adjust the position of the super jumbos, making sure that they are long enough to allow the propeller to turn without hitting the jumbo-straw crosspiece. Staple through the sticks and the super jumbo straws. Exploring Flight Staple

15. 6. Cut off the tips of the super jumbos flush with the sticks, and cut the jumbo crosspiece to a convenient length. Attach the rubber band between the prop and hook, and FLY! Exploring Flight Rubberband Analyze your plane model. How can you check to see if it is built properly?

17. Flight Line (4m) Exploring Flight

18.  Conclusion:  What is a system?  Why is your plane and flight line a system?  Hypothesize: How can you change the velocity of the plane?  What are some controlled investigations we can conduct with the plane?  Why is it important to study variables? Exploring Flight
