What did I do?
We were making a balloon, using Balloons, Straw, wheels, and cardboard. The purpose of making balloon cars helped us learn and investigate about Newton’s Laws. The Criteria was to make the balloon car to move by it self and also with weights.
What did I learn?
I learned about Newtons 3 laws and how they act. For the first law, it states that an object will only move when another object acts on it. Just like that, a balloon car needs the air in the ballon released to make the car move, because the air have enough force to push the balloon car. The second law states that, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. As for the balloon car, it means that if the mass is larger it needs more force to push it; when the mass is smaller, it needs less force to push it. For the last Newton’s law, for every action, there is an equal and opposite reaction. When this law acts on the balloon car, it means that the air in the balloon car (opposite force) push the car to move.
What worked?
The laws did act on the balloon car, because the car did need force to push it, also it do have an opposite force that acted on it. Now after the experiment, I understand the Laws of Newton.
What did not work?
At first the balloon car did not work, because we tied the rubber band securing the balloon car too tight. Later we found out about that and loosen the rubber band that made the balloon car able to run faster and more smooth, because more force was released.
Personal Relevance
This unit of balloon cars helped me learn about Newton’s Laws and helped me notice that everything in real life need Newton’s laws to work. Such as a leaf dropping from a tree, both the firs, second, and, third law is all acting on it.
