In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this activity, learners explore how to protect their skin while applying pesticides to plants.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

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

In this activity, learners discover that some things only stand up while they are spinning.

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

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

Learners follow a three-step process to start their own rock collection.
