General Physics Science Fair Project

Exploring Color and Water Depth

Exploring Color and Water Depth | Science Fair Projects | STEM Projects
Let's investigate how the color of objects changes as they are submerged deeper into the water. We'll use a boat, scuba diving gear, an experienced diver, a camera, and colored metal balls to observe the effects of water depth on color.


The hypothesis is that the color of the red and yellow balls will reduce in intensity as the balls are submerged deeper into the water.

Method & Materials

You will need to rent a boat and scuba diving gear, and hire an experienced diver. You will also need a high resolution underwater camera with flash, an underwater handheld flood light, and a depth gauge. Lastly, you will need colored metal balls - red, yellow, green and blue - and a black marker pen.
You will take a trip to the chosen diving location with the diver. Using the black marker pen, write the colors of the metal balls on its surface. The diver will take photographs of the metal balls at depths of 5 meters, 10 meters, 15 meters and 20 meters.


The results show that the color of the red and yellow balls cease to be visible at depths of 15 meters and 20 meters under water. This proves that the hypothesis is correct.

Why do this project?

This science project is interesting because it explores how the color of objects changes as they are submerged deeper into the water. It also shows how the wavelength of light affects the visibility of colors in water.

Also Consider

Consider repeating this project using balls of different colors such as violet, brown, white, orange and pink. Also, try to do the experiment in fresh water instead of sea water, or at night in the absence of any natural sunlight.
