In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this activity, learners make three different "seed" types and determine which design flies the farthest.

In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In this math game (Page 17 of the Are You Game? PDF), learners investigate probability by tossing coins.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this activity, learners participate in fun movement activities while playing on a giant game board. Use this activity to get learners involved in physical activity.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this lesson, learners are challenged to discover the relationship among six numbers.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.
