Earth Art
Source Institutions
In this activity, young learners will model land and water on the Earth's surface to make a unique piece of "Earth Art." Activity includes materials list, step-by-step instructions, STEM connections a

Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

Sharks: Taking a Bite Out of The Myth
Source Institutions
In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

Changing Shadows
Source Institutions
In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

Signs of Life
Source Institutions
In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

Water Bugs
Source Institutions
Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

Dinosaur Footprints & Fossils
Source Institutions
In this activity, early learners simulate fossil prints in play dough or clay.

A Crayon Rock Cycle- Sedimentary
Source Institutions
This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

Weather Stations: Winds
Source Institutions
In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

Bernoulli's Blowout
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Automotive Emissions and the Greenhouse Effect
Source Institutions
In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

Teen Moon: Moon Ooze
Source Institutions
In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

Let's Bag It
Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

Weathering and Erosion
Source Institutions
In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.

The Effects of Acid Rain
Source Institutions
In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
