This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!

In this activity, learners explore the great pump in their chests--the human heart!

In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.

In this activity (located on page 2 of PDF under GPS: Baby Dinosaurs Activity), learners will look for a relationship between skull size and body length among various dinosaurs.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.

In this activity (4th on the page), learners conduct a series of tests to find out which of their ears is more dominant.
