The Science of Trajectories: Catapults [|Video] [|NC Trajectory] PLAN! Build your Trajectory Apparatus Immediately. Draw a model diagram of your apparatus. Show your dimensions. Keep good records.
 * Remember to thank everyone who helps you. You will need a lot of help to succeed. Be Polite. Please, Thank you, May I?
 * What materials will you need?
 * How can you get your materials?
 * Who will help you cut the wood and drill holes?
 * Make the device as neat as you can; looks don't count but it is in the //spirit// of our team.

 * What size are you going to make? Size does matter. Keep with in the limits.
 * How will you change the angles for your launches?
 * Always measure the minimum and maximum distance your catapult will shot the ball.

Use Experimental Design ideas to test your equipment.

As you test the catapult, you will get feedback to see how to improve your device. Have you identified the variables that will determine the distance? the accuracy? the repeatablility? Check only one variable at a time. Record what you did, when you did it, how you did it, as well as your results. Have fun with this!!
