CRASH TEST
Aim
The aim of this experiment was to perform a crash test and analyze the damage done to a dummy, when wearing and not wearing a seatbelt.
Introduction
Controls and Variables
While performing this experiment there was one clear independent variable, which was the seat belt, as it was the only thing that changed during the experiment. As to have a fair test, that dummy had to be tested with both the seat belt on and off. The dependent and independent variables are the same thing in the experiment as, the effect of the seat belt is being both measured and changed. The controlled variables in this experiment was the angle of the ramp and using the same car. These variable were kept the same throughout the whole experiment, because if …show more content…
Safety
Risk
Level of risk
Steps to avoid risk
Dropping bricks
Moderate
Carry bricks with care and make sure bricks are kept in a stable position to ensure they won't fall.
Splinters
Low
Carry ply with care
Consuming Sand
Low
Do not eat moving sand or put finger in mouth after touching the sand.
Results and Observation Experiment 1- No seatbelt
The first experiment was the control. The car rolled down the ramp into the brick, as predicted the dummy flew off the car and landed on the road. If this experiment was done on a more practical scale the dummy would most likely be dead, as there was no seat belt to stop the dummy coming off the car and injuring themselves.
Experiment 2- Seat Belt
The second experiment was done with a seatbelt. It was hypothesised that the dummy would remain in the seat belt upon impact, hence less injured than the first experiment. This hypothesis was true, as the dummy did not suffer and significant injury, and the seat belt, improved the dummies chance of surviving the crash.
