In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.
