In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this activity, learners build their your own seismograph with household materials to document shaking.

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.

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.

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 will explore what a constellation is and make their own.

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.

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.

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

In this activity, learners work in groups to create a time line representing significant moments in their lives.
