Observing Air Pressure Weather Science Experiment
In this fun and easy science experiment, we’re going to explore and investigate weather by observing air pressure.
- Place the ruler on a table so that two inches hang over the edge.
- Place a double sheet of newspaper over the ruler.
- Align the edge of the newspaper with the edge of the table.
- Strike the edge of the ruler.
How it Works:
When you strike the ruler, the newspaper will not move as the air pressure on the newspaper will hold it down. Air pressure is simply the weight of all the tiny air molecules that press down on you and the Earth. It is this air pressure, or weight of the air molecules, that hold down the newspaper.
