In this inquiry investigation, students discover that the Earth is tilted on its spin axis, and that the tilt is responsible for the seasons. Supplies required include a globe, flashlights, golf tees and blue-tak. This is the ninth of 10 inquiry... (View More)

In this inquiry investigation, students conclude that the motion of the Earth is linked to the changes we observe such as the length of the day. Students learn about the reason behind the Earth's time zones. An optional water clock and sand clock... (View More)

Images, charts and text aligned to the Students' Cloud Observations Online (S'COOL) project are presented on this PDF version of a two-sided classroom poster. S'COOL engages students in making and reporting ground truth observations of clouds then... (View More)

This inquiry activity supports student understanding of the cause of light, heat and shadow, how to measure the passage of time, and how to use rules and other measuring tools. Students make observations using shadows, a meter stick, and a homemade... (View More)

In this inquiry investigation, students discover how a given amount of light changes in intensity when the area it shines on changes, and that change in light and heat occurs when the Earth is tilted towards or away from the Sun. Supplies required... (View More)

In this activity, students become familiar with the orientation of shadows, their size in relation to the object casting them, and how the alignment of the Sun, the object, and the shadow tells us much about how shadows work. Supplies needed for... (View More)
