Project cost ($):
It will take an hour to set up the experiment, and 3 hours to conduct it.
The swim caps can be purchased from a sports store.
Ensure that all of the participants are confident swimmers and have a life-guard on standby at all times.

This experiment was done to investigate if using a swimming cap can help a swimmer swim faster.
Using the swimming cap will help to increase the speed of the swimmer and he will be able to swim the 100m dash in a shorter time.
The swimming cap
The type of swimsuit a swimmer wears is important. Whether or not a swimmer wears a swimming cap is an important consideration as it affects his performance. A cap protects a swimmer’s hair from the chlorine in the pool. But more importantly, it improves the performance of a swimmer because it reduces the amount of drag/resistance.
Drag, chlorine, latex, polyester, nylon, Lycra
The materials required for the experiment are as follows:
1. For this experiment, whether the swimmers swim with or without a cap is important, is the independent variable. The dependent variable is the amount of time the swimmers take to swim 100 meters. Measure this using a stopwatch. The constants (control variables) are to be the participants’ age, the distance they are to swim (100m), and the temperature of the water in the pool.
The swimmers swam more quickly when they wore swim caps.
Use the graph below to plot your results.
The hypothesis holds true: the participants swam faster when they wore caps. They swam more slowly when they did not wear caps.
Get participants to wear swimsuits that are made of different materials.
