Balloon Powered Car
Problem: In order to create a race car that can travel a minimum of eight meters powered by a nine inch balloon. We need incorporate Newton's Law of Motion including speed, velocity, and acceleration. Hypothesis: If a car were to be made out of homemade materials, then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials. Dependent Variable: The results of speed and distance from the car responding to the materials Rationale: In this experiment, the challenge is to build a balloon powered car from homemade materials that can travel at least 8 meters. According to Newton’s Third law, it is possible to accomplish this objective. Force is any push or pulls and can be measured in newtons. The first law states that an object at rest will remain at rest unless acted upon by an opposing force. It also says that if an object is in motion will stay in motion unless acted upon by an unbalanced force. Also, during research it was found that Newton's 2nd law states that an object's acceleration depends on the mass of the object and the force acted upon it. This law is expressed in the equation, F (force) = M (mass)*A (acceleration). The third law explains that when an object exerts force on another object that object exerts force back. The objects would equal each other in magnitude but go the opposite direction. Materials:

1 straw
9 inch balloon
2 coasters
Hot glue/Duct tape
2 plastic lids
1 skewer
Procedures Part A
Put on safety goggles first because there will be many sharp and hot objects used in making the car. Cut the bendable part off a straw.
Insert a wooden skewer so that it moves freely within the straw. Push one end of the skewer through the middle of one of the coasters and repeat on the other side. Hot glue the wheels in place but...
