In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this math lesson, learners explore polynomial and rational function patterns.

In this activity (18th on the page), learners conduct an experiment to examine memory.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

In this activity (on page 134 of the PDF), learners explore reaction time.

Millions of organisms can live in and around a body of water.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity described on pages 2-3 of the PDF, participants debate whether there there's life elsewhere in the universe.

In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

On an imaginary fossil hunt, learners "find" (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.
