Make Your Own Barometer!

Make Your Own Barometer! | Science Fair Projects | STEM Projects
Have you ever wondered how to measure air pressure? With this project, you can make your own barometer and use it to predict the weather!


The hypothesis is that air pressure can be measured with a homemade barometer.

Method & Materials

You will make a barometer out of a coffee can, balloon, rubber band, pin, glue, straw, and paper.
You will need an empty coffee can, a large balloon, a large rubber band, a pin, glue, a straw, and paper.


After making the barometer and taking several daily readings for a week, it was observed that the readings of the barometer outside were different than those of a barometer inside.

Why do this project?

This science project is interesting and unique because it allows students to make their own barometer and use it to measure air pressure and predict the weather.

Also Consider

Experiment variations to consider include measuring air pressure in different locations and at different times of day.
