This is a classic exercise for visualizing the scale of the Solar System.

This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.

This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

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

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
