In this lesson, students explore how eclipses happen and why Einstein needed a total eclipse to image stars near the Sun in order to demonstrate how the Sun's mass bends the light from a far away star. Using a foam ball and a lamp, learners create a... (View More)

This activity, effective outdoors or indoors, demonstrates how insolation is affected by latitude by using a pair of thermometers, each taped to some cardboard, placed outside on a sunny day. A globe can also be used, outdoors or indoors. Students... (View More)

This is an activity about measuring angular size and understanding the solar and lunar proportions that result in solar eclipses. Learners will use triangles and proportions to create a shoebox eclipse simulator. They will then apply what they learn... (View More)

This activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More)

This is a lesson plan for an activity illustrating the reasons for the seasons. Learners predict sunrise, noon, and sunset positions on the dates of the equinoxes and solstices, observe these positions in a planetarium, plot their data on graphs,... (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 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)
