The student is concerned about pollution caused by gasoline-powered cars and wonders if balloons could power cars instead. They conduct an experiment to test how far different types of homemade cars move when blown by balloons. A plastic car and Lego car are each tested 4 times with balloons blown to different strengths. The results show the Lego car, being heavier, travels farther each time due to greater momentum keeping its wheels spinning longer. The student concludes that a car's weight impacts how far it can move when powered by balloons.

1. Nowadays cars are run by electricity and
fuel which pollutes the air. How could we
prevent that from happening? So I wonder if
cars could be powered by something
alternative like balloons? I am going to test
out what benefits a car by its weight. I think
that the best choice is the plastic car
because it is lighter
Materials
Balloons
Homemade car
Camera
Lego car
Straws
Procedure
1. Build cars
2. Blow up balloons
3. Shoot photos
4. Gather results
5. Conclude
6. In conclusion I found out that the
balloon has to be straight for the car to
actually go in straight direction. I also
noticed that the Lego car which is
heavier went further than the plastic
car. I think that the Lego car went the
furthest because of the momentum of
the car since it is heavier the wheels
will spin longer.
