Cold Front Weather Science Experiment
In this fun and easy weather science experiment for kids, we’re going to explore and investigate a cold front.
- Plastic cup
- Blue food coloring
- Fill the plastic cup about halfway with water.
- Add a drop of blue food coloring.
- Put the plastic cup in the refrigerator for at least an hour.
- Fill a glass about halfway with room temperature water.
- After an hour, pour the chilled water into the glass of room temperature water.
How it Works:
The cold water should push to the bottom of the glass. A cold front will behave in a similar fashion and push warm air up and out of its way as it moves and squeezes under the warm air. A cold front is where a cold air mass replaces a warm air mass. Cold fronts typically move northwest to southeast and often bring gusty winds, heavy rain, temperature drops, and even thunder and lighting. Cold fronts are represented by a blue line with triangles pointing toward the direction warm air is being replaced on colored weather maps.
Make This A Science Project:
Observe the local weather forecast and determine when a cold front is heading your way. Go outside and observe the weather.
