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 propeller boat showing: the boat base made of ice cream sticks, the straw passing through the sides, the bottle cap propellers with attached ice cream stick blades, and the rubber band mechanism. Measurements should include the length and width of the boat base, the position of holes for the straw, and the size of the propeller blades.
Explanation
The chapter provides detailed steps for making a propeller boat using ice cream sticks, straws, bottle caps, and rubber bands. The propeller is a wheel with blades that pushes through water to create movement. The rubber band stores energy when wound up and releases it to turn the propeller.
