General Physics Science Fair Project

Hydroelectric Power

Easy
Hydroelectric Power | Science Fair Projects | STEM Projects
In this experiment, you'll explore the power of water pressure and how it can be used to generate electricity.

Hypothesis

The hypothesis is that water pressure can be used to generate electricity.

Method & Materials

You will cut the top off a milk carton, punch holes in the side, and tape them up. Then, you will fill the carton with water and remove the tape to observe the water pressure.
You will need a half gallon paper milk carton, a gallon of water, an awl or 10p nail, masking tape, a ruler, a magic marker, a pair of scissors, and a pad of paper and pencil to make notes.

Results

The results showed that the water from the bottom of the milk carton went the furthest. This demonstrates the power of water pressure and how it can be used to generate electricity.

Why do this project?

This science project is interesting and unique because it shows how water pressure can be used to generate electricity, which is a common source of energy used in many places.

Also Consider

Experiment variations to consider include using different sizes of holes in the milk carton and using a water bottle instead of a milk carton (see videos).

Want to witness the power of water under high pressure? Watch as this teacher uses a lit BBQ skewer to create holes in a water bottle and see for yourself how the water flows out of the bottom holes at a faster velocity, demonstrating the incredible force that can be generated by water.
Check out this awesome experiment where a student uses a penknife to cut holes in a water bottle and observes how the water flows out at different speeds depending on the position of the hole! It's this power of water that makes hydroelectric power a possibility!
