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

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.

Current Events
Source Institutions
Learners model the ocean currents that carry hot water from the tropics to northern latitudes.

Tree Trunk Diameter to Branch Height Relationship
Source Institutions
In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

Topographic Investigation: Map an Underwater Surface
Source Institutions
In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

Exploring the Solar System: Moonquakes
Source Institutions
In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

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

Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Colors of Stars
Source Institutions
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.

Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

Convection Demonstration
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

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

A Universe Without Supernovae
Source Institutions
This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

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

Moving Model Glacier
Source Institutions
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.

Eyedropper Hydrometer: Buoy your understanding of density
Source Institutions
Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

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

Tomb Mapping
Source Institutions
In this activity, learners examine the culture and history of the tomb site.

Resource Hunt
Source Institutions
In this activity, learners explore nonrenewable resources and learn why these resources are finite.

Looking Back Through Time
Source Institutions
In this activity, learners create their own archaeological profiles.
