How Do You Build A Car For A Science Project?
A Styrofoam car propelled by a balloon can teach your child many scientific concepts. Building the car and watching it go down a runway, your child can observe propulsion, thrust and Newton’s third law of motion, which states that “every action has an equal and opposite reaction.” Use a marker and ruler to draw a rectangle with dimensions 7 1/2 centimeters by 18 centimeters on a flat piece of Styrofoam. Then cut the rectangle out. Use a compass to draw four circles that are 7 1/2 centimeters in diameter on a second piece of flat Styrofoam. Cut all four circles out using scissors. Stretch a medium-sized latex balloon. Stretch the balloon out several times to make it loose. Test the balloon to make sure it is loose by blowing it up once and letting the air back out. It should be easy to blow it up. Place a bendy straw into the mouth of the deflated, stretched balloon. Insert the straw up to the bendy section. Use tape to secure the balloon to the straw. Wrap the tape around the mouth of
