Why Do We Have Seasons Weather Science Experiment
In this fun and easy weather science experiment, we’re going to explore why we have seasons.
- Medium sized Styrofoam ball from the craft store
- Lamp with the shade removed
- Pencil, bamboo skewer, or knitting needle
- Sharpie or marking pen
- Mark the top of the ball with the letter N.
- Mark the bottom of the ball with the letter S.
- Draw a circle around the middle of the ball to represent the equator.
- Set the lamp in the middle of a room.
- Push the pencil through the N and S marks on the ball.
- Now tilt the N slightly toward the lamp.
- Turn on the lamp and observe what parts of the ball are illuminated.
- Be sure to note the wall toward which the ball is pointing. You will need to point the ball toward this wall for the remainder of the demonstration.
- Now move 90 degrees from the spot of your original observation.
- Observe which parts of the ball are illuminated at this location.
- Move another 90 degrees and observe.
- Now move the final 90 degrees and observe.
How it Works:
Certain seasons have longer and shorter days, not because of the Earth’s distance from the sun, but because of the tilt of the Earth.
Make This A Science Project:
Try tilting the Styrofoam ball differently and observe any changes. Try holding the ball further from the lamp. Try holding the ball closer to the lamp.
