In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

Learners build a wind turbine and test it to see how much energy is created.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity (Lesson 1), learners work in groups to create tide simulations.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.
