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 explore how light and dark colored objects absorb the Sun's radiations at different rates.

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.

In this activity, learners explore the Great Plains.

In this activity, learners will explore what a constellation is and make their own.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

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

In this activity (on pages 11-12 of PDF) learners create models of lava layers that have formed on the moon.

Learners model the ocean currents that carry hot water from the tropics to northern latitudes.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
