Cleaning with Dirt
Source Institutions
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Lava Layering: Making and Mapping a Volcano
Source Institutions
In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.
Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
Heavyweight Champion: Jupiter
Source Institutions
In this activity, learners confront their perceptions of gravity in the solar system.
Cloud Fun
Source Institutions
Learners complete a series of hands-on and investigative activities to explore cumulus clouds.
Geometry and Algebra: The Future Flight Equation
Source Institutions
In this activity, learners discover how NASA engineers develop experimental aircraft.
Heavy Lifting
Source Institutions
In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).
Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.
Ocean Home: Swimming Fishes
Source Institutions
In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.
Spectroscope
Source Institutions
In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.
Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
Who Dirtied The Water?
Source Institutions
In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).
OBIS Oil Spill
Source Institutions
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.
Regolith Formation
Source Institutions
In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
Exploring an Ecosystem
Source Institutions
In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.
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.
Cool It
Source Institutions
In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.
