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

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

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.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

In this activity, learners will plot the distribution of various oozes using information from sediment maps.

In this coin math activity, learners sort and stack 100 (one hundred) pennies into piles of 5 pennies each, 10 pennies each, and 20 pennies each.
