Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.

Learners take on the role of environmental engineers as they design water filters.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.

In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.

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

In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.

This lesson (on pages 46-55 of PDF) features two strategy board games -- one from Ghana and one from China. The first game, Achi, is a cross between checkers and tic-tac-toe.

The popular sudoku puzzles use numbers, but the game could played with any set of 9 different objects!

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

In this nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food labels

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

Data in computers is stored and transmitted as a series of zeros and ones. Learners explore how to represent numbers using just these two symbols, through a binary system of cards.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.
