Draw a sketch of the toy, giving accurate measurements where different parts are connected. You can paste a photograph of the toy in the space given below:
A labelled diagram of the catapult or robotic arm showing the ice cream sticks, rubber bands, spoon (for catapult) or bottle caps (for robotic arm) with accurate measurements of length and width of each component. The fulcrum/hinge point should be clearly marked where the lever pivots.
Explanation
The chapter provides step-by-step instructions for making a catapult using ice cream sticks, rubber bands, and an ice cream spoon. The catapult uses a single lever that pivots at a fixed point (fulcrum). Students should show measurements of the stacked ice cream sticks, the position of the rubber bands, and the spoon attachment point.
