Description | ||
| The objective of this science fair project is to compare the ability of different brands of bicycle helmets to absorb shock. The experiment will be carried out by dropping a 3 kg weight on the helmets and measuring the pressure of the impact using a ball and pressure gauge. | ||

| 1. The independent variable in this science fair project is the type of the bicycle helmet used. The dependent variable is the air pressure in the ball when the weight hits the helment, which is determined by measuring the maximum deflection in the air pressure gauge. The constants (control variables) are the height from which the weight was dropped, the mass and size of the weight, the size of the helmet, the size of the ball, and the initial pressure of the ball. 2. Three different brands of bicycle helmets will be used in this experiment. The Giro Indicator ..... | ||
