Seasons is a free and innovative 8-day unit that provides interactive videos, hands-on activities, lesson plans, and student worksheets to explore the causes behind Earth’s seasons. The curriculum uses a combination of Earth- and space-based visualizations and models to address common misconceptions and strengthen students’ spatial reasoning skills. Seasons is aligned with standards for middle school Earth and Space Science (NGSS MS-ESS1-1).
The program covers the Sun’s apparent motion in Earth’s sky; Earth’s motion around the Sun; Earth’s tilt; the tilt’s relationship to the seasons; and energy transfer from the Sun to Earth. Join us as we use WorldWide Telescope to journey around the solar system to better understand the causes of seasons on Earth!

Seasons on WorldWide Telescope
All of the Seasons videos were made using WorldWide Telescope (WWT), a free, interactive software that models our universe and allows users to record tours of their explorations. WWT requires Windows, so the tours are converted into videos for accessibility. However, if you would like the (optional) fully-interactive experience, follow the steps below to install and run WWT.
Download the Seasons WorldWide Telescope tour file (.wtt) from Zenodo.
How do I run a WWT tour on my computer?
You will need to download WorldWide Telescope to your Windows computer to run a WWT tour file.
- Download WWT (for free) from worldwidetelescope.org.
- Download the Seasons WorldWide Telescope tour file (.wtt) above.
- Double-click the .wtt file to open and run the Seasons tour.
