Elliptical Orbit—
Overhead Demonstration Kit
How do planets travel around the Sun?
This simple overhead apparatus helps illustrate the elliptical orbits of the planets. Students will use observations from the teacher demonstration and perform math- ematical calculations to find the elliptical orbits. Easily fits on any standard overhead projector. Kit includes the overhead demon- stration device, string and a set of markers. Complete with teacher instructions and detailed background section.

Earth’s Orbit and Seasons— Demonstration Kit
What causes seasons on Earth? How does Earth’s revolution around the Sun influence the changing of the seasons? Demonstrate and explain the answers to these questions and more with this low-cost, highly visual kit! The Earth model allows students to observe the seasonal changes in both the Northern and Southern Hemispheres and the variation in day length in different areas of the world throughout the year.
AP6150 I $14.05
Orbital Speed— Demonstration Kit
Demonstrate orbital speed and centripetal force with this unique handheld device. Students use data collected during the demonstration to calculate the orbital speed of a stopper and discover relation- ships between gravitational force, orbital radius and orbital speed. A great activity to show that in order for a planet, star or satel- lite to maintain orbit, the object must travel at a specific speed. Instructions and repro- ducible student worksheet provided.
