This lesson attempts to correct the common misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. Proceeding from student preconceptions, small groups participate in an exploration of the cause of the seasons... (View More)

This lesson addresses the common student misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. This lesson encourages students to voice this misconception at the beginning of the lesson and then attempts to... (View More)

In this laboratory activity, learners explore the difference between heat and temperature, and explore the rate of heat transfer from one substance to another as it depends on the density of the substances being investigated. The activity can be... (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 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)

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)
