Newton’s Law of Action and Reaction states that when an object is pushed, it pushes back. Kindergarten students learned this firsthand by using a balloon, a straw, and a piece of string! The walls of the balloon push the air out as it opens. Likewise, when the balloon pushes against the air, the air pushes back. As a result the balloon travels along the string that it is attached to. Not only did this experiment demonstrate cause and effect, action and reaction, and involve gas (the state of matter we are currently studying)- it was tons of fun. Even our youngest students thrive on competition!
