In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this math activity, learners read "The Button Box" by Margarette S. Reid and then make their own button boxes filled with different buttons.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.
