In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.
