In this experiment, learners float colored ice cubes in hot and cold water.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this activity, learners will plot the distribution of various oozes using information from sediment maps.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners will compare predicted and observed tides using data from The National Oceanic and Atmospheric Administration(NOAA).

Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

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

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.
