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

This demonstration activity models how Venus appears from Earth.

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 "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

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 will explore what a constellation is and make their own.

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

In this activity, learners will discover how our universe is continuously expanding.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

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 investigate the concepts of relative size and distance by creating a basic model of the solar system.

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

In this activity, learners will create their very own constellation.

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

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 build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

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