Molecules in Motion
Source Institutions
"Molecules in Motion" explores how materials behave and change in a vacuum.

Zoom: Travel to a Star and Back to Earth
Source Institutions
This is an online activity about what would happen if we could travel at or near the speed of light.

Coral Snapshots: Biodiversity in Marine Protected Areas
Source Institutions
In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

Constellation Scope
Source Institutions
In this activity, young learners explore the basic shapes of constellations by making their own scope out of a cardboard tube and paper with pinpricks.

Personal Time Line
Source Institutions
In this activity, learners work in groups to create a time line representing significant moments in their lives.

Create a Compass
Source Institutions
In this activity, learners use simple materials to build their own compass.

Go with the Flow
Source Institutions
Learners draw comic-style pictures to show the water cycle. From a starting picture, one learner draws what happens to the water in the next panel, then passes the comic strip to another learner.

Locating a Point
Source Institutions
In this activity, learners work in teams to simulate the process used by Global Positioning Systems (GPS) to determine the location of a fallen meteorite in Antarctica.

Light of the Moon
Source Institutions
Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

Making Waves
Source Institutions
Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

Exploring the Universe: Objects in Motion
Source Institutions
"Exploring the Universe: Objects in Motion" encourages participants to explore the complex but predictable ways objects in the universe interact with each other.

Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

The Best Dam Simulation Ever
Source Institutions
This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

Cookie Paleontology
Source Institutions
In this activity, learners will explore paleontology and archaeology. They will learn about technique as they excavate raisins and chocolate chips from cookies.

Buzz Lightyear Connect It!: Flight Path Activity
Source Institutions
In this activity, "space cadets" (learners) use writing and sequencing skills in addition to directional words/ordered pairs to guide Buzz Lightyear (from the movie "Toy Story") through a grid to reac

Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

Energetic Water
Source Institutions
In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

Does Air Weigh Anything?
Source Institutions
The demonstration/experiment provides quick proof that air has mass.
