Building a Catapult




You will design, construct and test a cotton ball catapult. You will have a limited number of materials to use and you MUST use all of the materials that are given to you. Monday, you will compete with the other students in your class to determine which catapult is most effective.




Material:

1 cotton ball 1 paint paddle (stir stick) 1 12 oz paper cup 1 thumb tack

50 cm of masking tape 1 plastic spoon 2 paper clips

4 rubber bands 1 sheet of poster board




Procedure:

Design, on paper, a cotton ball catapult with the materials provided. ALL of the materials MUST be used to build the cotton ball catapult. The materials can be cut, bent, torn or otherwise altered, but NO replacement parts can be used. And, you may not embed the thumb tack, or any other materials, in the cotton ball.
In your design, be sure to label the simple machine you will use and explain how your cotton ball catapult will work.
Once your design is drawn and labeled, you may begin the construction of your catapult. Make sure you test it! You may make changes to your design (make sure you note this on your sheet.)
Bring the catapult to school on Tuesday, October 19, where you will compete against other students for title of Catapult King or Queen.
You will be graded on:
Design Sheet-must be labeled with the supplies and types of simple machine and description of how the catapult works.
The Catapult-you used all and only the required materials.
