In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

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

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
