This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.

This activity is designed to let learners measure their reaction time or response time to something they see.

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

In this activity (page 3 of the PDF), learners will observe a physical change.

This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

In this activity, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.

In this activity, learners explore the process of condensation.

In this activity, learners create their own experiment and test which of 4 mixtures of household chemicals turn pennies green over 5 days.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this health activity (on page 3 of the PDF), learners will learn about the body‘s defenses against invasion from tiny particles.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.
