"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

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.

The "Exploring the Solar System: Magnetic Fields" activity shows participants how scientists can use tools to study the invisible magnetic fields of Earth, the Sun, and other objects in the universe.

In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.
