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

In this math lesson, learners practice reading charts and graphs by creating and interpreting glyphs.

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

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

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

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

In this math lesson, learners extend their understanding of basic probability concepts as they learn to name all of the possible outcomes of an event as well as ways to express the likelihood of such

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.
