In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

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

En esta actividad, los aprendices harán un terrario usando materiales simples.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

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 will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

In this activity about magnetism (page seven of the pdf), learners experiment with magnets to better understand how magnetic fields work.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this activity, learners will explore the water cycle by creating a small atmosphere.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
