5 Fun Science Ideas for the First Day of Fall

5 fun science ideas for the September equinox

K - High School

Are you a science teacher looking for simple, low-cost ideas for the first day of fall? Ward’s has you covered.

Now that the first month of the new school year is almost over, you may be looking for some new inspiration. Try these 5 fun science ideas for the September equinox on the 22nd, or throughout the fall. Don’t worry: most are pretty easy (and free!).

1. A Stroll through Nature

Now’s the time to take your class outside (while it’s still dry). The outside environment can provoke lessons and conversations about a bunch of different subjects, depending on what you teach.

You could also have your students collect leaves, rocks, flowers—anything they find interesting or that represents the new season. This stimulates experiences that are meditative or expressive (especially in a culture of constant cell phone use and staring at screens like zombies).

2. Fun with Leaves

Have your students take those leaves they collected, add different kinds of lettuce and coleus or hosta, and do a leaf chromatography activity! Before the activity, students can form a hypothesis about the pigments they’d expect to see based on their leaf selection. Just use a variety of leaves with a higher water content.

Check out the activity here.

3. Fall Around

Your students can search for pictures throughout the world of different places during fall. It would probably be best if they have pictures from both the Northern and Southern Hemispheres. Have them make a collage and encourage them to be creative.

This could be a great way to launch into why the seasons change. Use a solar system model. Or you can have the students act as the Earth and the Sun. Close the curtains and give a flashlight to the one playing the Sun. Tell them about how the Earth is tilted forward. Try to question them so they find out by themselves how this causes a difference of seasons depending on whether you’re in the Northern or Southern Hemisphere.

4. Out-of-This-World Equinoxes

The September equinox is occurring at 3:50 am on the 23rd. The sun will cross the celestial equator, and there will be (roughly) equal amounts of day and night on the Earth. But what about other planets? They have equinoxes too.

You could have student groups pick different planets and have them report on their tilts and equinoxes. After all, the universe doesn’t revolve around the Earth.

5. Might Makes Right

Physics teacher? You can use the change of seasons as a starting point to explain centripetal and centrifugal forces. Have a ball on a string (the Earth) and swing it around (just don’t don’t hit anyone!). The next trick you could try is swinging a bucket of water in a circle.

Or, just for kicks, students always love a flying pig.
