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.

Mirror, Mirror
Source Institutions
In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

Buried Bones
Source Institutions
In this activity, pairs of learners will create two make-believe dig sites by burying chicken bones in plaster of Paris--a powder that hardens when wet.

Solar Spin
Source Institutions
A group of learners models the Sun shining on the Earth. By rotating the Earth, they demonstrate how the Sun only shines on a portion of the Earth at a time.

Sea Level: On The Rise
Source Institutions
Learners will understand the relationship between climate change and sea-level rise.

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

Candy Chemosynthesis
Source Institutions
In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

What's the Difference between Weather and Climate?
Source Institutions
In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

Detectives de arena
Source Institutions
¡En esta tira cómica, Mateo y Cientina son detectives! Ellos usan sus destrezas investigativas para identificar de dónde provinieron algunas muestras de arena.

Wetland Filter Model
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

Pepper Scatter
Source Institutions
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

Exploring the Universe: Imagining Life
Source Institutions
“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

Knowing North: Understanding the Relationship between Time and the Sun
Source Institutions
This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device.

Woodpecker
Source Institutions
In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

Play Dough Moon Phases
Source Institutions
In this activity, young learners will learn about moon phases using materials found at home. This activity is adapted using play dough and cups to avoid food allergens and waste.

Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

Exploring the Solar System: Story Blocks
Source Institutions
In this collaborative storytelling activity, learners and caregivers develop a strong story about science and exploration.
