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

Are Microbes Alive?
Source Institutions
In this activity (on pages 19-21 of the PDF) learners observe mold growing on potatoes. Preparation for this activity has to start a week before, to allow time for the mold to grow on the potatoes.

Hieroglyph Holiday
Source Institutions
In this activity about archaeology, learners will explore different Egyptian hieroglyphs and recognize their meanings and uses.

The Daily Ups and Downs
Source Institutions
In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

Coma Cluster of Galaxies
Source Institutions
In this activity, learners will first learn the basics of galaxy classification and grouping.

Melting Ice
Source Institutions
In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

Tiny Geyser Models
Source Institutions
In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.
Coral and Chemistry
Source Institutions
In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

Fossil Dig Site
Source Institutions
In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

Build a Coral Polyp
Source Institutions
In this activity, learners build one or more edible coral polyps and place them together to form a colony.

Watercraft
Source Institutions
In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

Which Parachute
Source Institutions
In this activity, learners will engineer three different parachutes to test how well each one works.

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

Using Different Models of Earth
Source Institutions
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.

Zany Zen Garden
Source Institutions
In this activity, learners will turn an ordinary tray of sand into a desk-top garden for meditation.

Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Wintergreen
Source Institutions
In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

Who Do You Think You Are?
Source Institutions
In this activity, learners use maps to locate the Northwest Coastal region.

Blue Sky
Source Institutions
In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
