In this fun gardening activity, learners discover their soil type. There are three basic soil types: sand, silt, and clay.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

How many colors make black? Gather as many water soluble black markers as you can find.

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.

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 physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity, learners determine whether thermal energy can be used for work.

In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside.

In this activity, learners explore the process of condensation.
