In this physics activity, learners will investigate the strength of egg shells.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.

In this activity, learners thread gumdrops together to make a model of a polymer.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

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

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

In this activity, learners use Starburst® candy to sort, classify, compare, and graph. Learners grab a handful of one-inch candy squares, sort them by color, graph the candy, and discuss the results.
