Elliptical Orbits Overhead Demonstration Kit

AP6464

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 mathematical calculations to find the elliptical orb...

Constellation Transparency Set

AP6600

Constellations are groups of stars in the shapes of mythical heroes, kings, queens, monsters, and gods. Introduce your students to four of the most famous constellations-the Gemini Twins, Orion the Great Hunter, Leo the Lion, and Ursa Major-the Great...

Lunar Phases Activity

AP6739

Why does the Moon appear to have different shapes that repeat on a monthly cycle? What do the terms waxing and waning mean? In this activity, students will be given lunar and solar longitude data and map the orbit of the Moon for a full month's time!...

Orbital Speed Demonstration Kit

AP7319

How do the radius of an orbit and gravitational forces affect orbital speed? In this demonstration, a unique hand-held apparatus will be assembled and used to demonstrate orbital speed and centripetal force. Students will use the data collected durin...

Planetary Orbits Student Laboratory Kit

AP7326

Let students see for themselves the difference between a circle and the elliptical path a planet follows as it orbits the Sun. In this hands-on activity, students construct ellipses and then explore the shape of a planet’s orbit as they investigate K...

Sun Scale Student Activity Kit

AP7251

What is the diameter of the Sun? How far is the Sun from the Earth? These seemingly imponderable “universal” questions can be easily answered using this simple but effective Sun Scale apparatus. Easy-to-assemble apparatus allows an image of the Sun t...
