The hypothesis is that the firmer the suspension, the faster the car is able to travel around bends.

You will install springs of different levels of firmness into a remote-controlled car, and then measure the time it takes for the car to complete a straight course, a clockwise course, and a counter-clockwise course.

You will need a Tamiya customized remote-control sports car, springs of different levels of firmness, an electronic metronome, a stopwatch, blank paper and pen, and 40 AAA batteries.

The results show that the hypothesis should be accepted. Overall, the stiffer the spring, the faster the car travels around bends. However, it is interesting to note that the springs of medium-firmness performed the worst for the round circuit.

This science project is interesting because it allows students to explore the relationship between the firmness of a car's suspension system and its speed around bends.

Consider experimenting with different types of tires to see if they affect the results, or testing the car's speed on different surfaces.
