Students model the tilt of the Earth as it orbits the Sun. They explain the meaning and characteristics of solstices and equinoxes. They explain that sunlight hits the Earth at different angles at different locations over the course of...

Students investigate the reason for seasons on Earth during three activities. They construct a model of the Earth and Sun to identify patterns in the changes of the angle of light on the Earth's surface. Then they conduct a heat...

Young scholars investigate a model of the tilt of the Earth in its relationship to the Sun during the different seasons of the year. They study the solstices and equinoxes, while determining how sunlight hits the Earth with different...

Young scholars engage in a study looking for the differences found during the cycle of one lunar month. They conduct research using a variety of resources. Then the information is used to construct a lunar calendar to observe daily...

Students study how the sun is at the center of the solar system.  In this solar lesson students measure the altitude of the sun and its size.

Eleventh graders connect art (photographs) to the historical period and conjecture about conditions during this era in American history, sharing ideas in class discussion. Each student completes a project on a period depicted in one of...

Students take digital pictures to create a unique viewpoint. In groups, they discuss if they have ever had a feeling of someone watching them. They use the digital camera as a "third eye" to see different perspectives. They answer...

The focus of this series of lessons is to engage students in an exploration of the world around them. The emphasis is on inquiry as students learn about the earth, sun, light, shapes and more.

This applet helps students visualize the shapes of shadows cast by a cube with a light coming from different angles. This helps students visualize shapes from different angles and to identify, sketch and classify the cross-sections of...
