Bicycle Helmet Shock Absorption

Bicycle Helmet Shock Absorption | Science Fair Projects | STEM Projects
In this experiment, we'll compare the ability of different brands of bicycle helmets to absorb shock. We'll drop a weight from a certain height and measure the air pressure in a ball inside the helmet. The results will tell us which helmet is best at absorbing shock.


The hypothesis is that a more expensive bicycle helmet will be more effective in reducing impact.

Method & Materials

You will arrange four bricks in a square, secure a bicycle helmet over a ball, and drop a weight from a certain height. You will measure the air pressure in the ball when the weight hits the helmet.
You will need a 2 meter long string, three different brands of bicycle helmets, a 3 kg circular weight, a basketball, an air pump, a pressure gauge, four bricks, a chair, and an assistant.


The results showed that the impact of the collision was approximately the same for the basketball, regardless of the brand of bicycle helmet used.

Why do this project?

This science project is interesting because it tests the ability of different brands of bicycle helmets to absorb shock. It also shows how important it is to wear a helmet correctly to minimize the risk of injuries.

Also Consider

Try repeating the experiment with different heights and heavier weights. Also, repeat the experiment with different brands and models of helmet.
