General Engineering Science Fair Project

Colorful Temperature

Colorful Temperature | Science Fair Projects | STEM Projects
We're going to paint five boxes different colors and measure the temperature inside each one. We'll see if the color of the box affects the temperature inside.


The hypothesis is that black and darker colored buildings will have warmer indoor temperatures compared to white and lighter colored buildings.

Method & Materials

You will paint five boxes different colors, seal them, and measure the temperature inside each one.
You will need cardboard boxes, paint, paint brushes, thermometers, scotch tape, and Play Doh.


The experiment showed that the black box had the highest temperature inside and the white box had the lowest temperature. The color of the walls on our houses can help reduce the temperature in our homes.

Why do this project?

This science project is interesting because it shows how the color of a building can affect the temperature inside.

Also Consider

Variations to consider include using shiny/glossy/reflective paint versus dull/matt colored paint, and using different colors and different materials such as plastic or metal containers.
