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

In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

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

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

This activity (located on page 4 of the PDF under GPS: Baby Dinosaurs Activity) is a full inquiry investigation to determine the age of fossils based on where they are discovered.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh
