Learners explore water's property of cohesion through two investigations.

In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this adapted version of poker, learners practice writing chemical formulas by playing this chemistry card game.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different
