The air is getting cooler, the leaves are starting to change color, and the days are getting shorter. In just a few days the autumnal equinox will be here in the northern hemisphere. Here are some resources for teaching and learning about the sights and sounds of autumn.
Sixty Symbols offers an eleven minute video about equinoxes and solstices. It’s not a video that most kids will find engaging, but I’m including it because in it you can see a demonstration of how you can use the free Stellarium software in your lessons.
To help students understand why the leaves change colors in the fall, the Maine Forest Service has an animated video explaining why leaves change colors. The video is titled Maine’s Autumn Magic and you can watch it here. To help students understand some of the terms in the video, the Maine Forest Service has a glossary of tree terms.
Although they’re not as informative as the two resources above, National Geographic has a couple of nice photo galleries of fall foliage. Click here for a small gallery of images from Acadia National Park. Click here for a gallery of images from the Adirondack Park.
Untamed Science offers a good, partially animated, explanation of why leaves change colors, what produces the colors, and why bright and sunny days are best for viewing red leaves. The video is embedded below.
Autumnal Colors is a short video produced by Thomas Rasel. The two minute video highlights the sights and sounds of autumn. A bugling elk and a squirrel preparing for winter are a couple of the sights and sounds included in the video.

Autumn Stars and Planets is a short PBS video that explains why the stars and planets that we see from Earth change with the seasons. The video is embedded below.
Reactions, a great YouTube channel from the American Chemical Society, offers a nice video about the chemistry involved in the process of leaves changing color. The videos explains how chlorophyll and the glucose stored inside trees help reveal the reds, yellows and, browns of fall foliage.
