State your question How does placement of the wings depend on how far the rocket will fly? B. Make a prediction showing what you think will happen in the experiment. If the wings are evenly spaced out then it will go farther because C. Create a data table. A.

D. List 5 controlled variables. Launch angle, amount of water in the cone, rocket, air pressure, location of launch. E. List the materials needed for the experiment. 2 liter pop bottle, 20 ounce pop bottle, card board, duct tape, water, air compressor, and a launcher. F. Write out a step by step procedure for carrying out the experiment. 17735299.doc

Place the 2 liter pop bottle upside down and put the 20 ounce bottle on top of it right side up. Tape them together with duct tape. Make 3 card board wings. Make them 10 by 5 inch. They should be right triangles. Cover them with duct tape. Tape it on the middle of the 2 liter bottle evenly spaced out. Between each trial move the wings around as it says in the table. Fill the 20 ounce bottle with 100 ml of water. Fill the 2 litter bottle with 400 ml of water. Now it is time to launch the rocket. Write a conclusion. 1. Does your data support your hypothesis? Why or why not? (Describe by referring to your data! Be sure you talk about your data and graph.) Yes it does. When the wings were evenly spaced apart it went the farthest. 2. What changes would you make if you did the experiment again and why? (Be specific to the individual experiment…NOT “Be more accurate” “Do more trials”) I would do it when there was no wind. I would also do all of the trials on the same day.
