In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

In this activity, learners practice matching and subitizing as they create the longest domino train possible.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

In this math activity, learners sort patterns into similar "families" or groups that have the same pattern, but different symbols.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
