In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

Did you know that you would be a different age if you lived on Mars? It's true!

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.

In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

This is an online Flash game where learners can experiment with ballistics and how to compensate for the varying levels of gravity found on the planets of our Solar System.
