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 activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

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

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.

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

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.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

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

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

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).

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

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this science/art activity, learners create an insignia or emblem for a planet exploration mission.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

In this activity (on pages 26-33), learners play parasitologists, solving several "mysteries" about people who got sick from various parasites. In teams of four, each member solves one mystery.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

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