The fifth graders have been doing many experiments in science to learn about motion and force. They have had to calculate the speed of a car by measuring the distance it traveled divided by the time it took in seconds. They conducted experiments to find out how friction, mass, and force affect the distance cars travel down a ramp. They were able to see Newton's 3rd law in action when they made rockets by attaching a balloon to a straw that went through a string. For every action, there is an equal and opposite reaction.
