Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
Moon's Long History: Impact Paintings
Source Institutions
In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.
Earth Attractions
Source Institutions
In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.
Making Regolith
Source Institutions
This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?
Don't Stop for Hitchhikers
Source Institutions
In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.
Mass, Area, Volume
Source Institutions
In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.
Black Holes: No Escape
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
Salt Water Revival
Source Institutions
In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.
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).
Pollen Tracks
Source Institutions
In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even
Shapes and Angles
Source Institutions
In this activity (page 7 of PDF), learners will identify the general two-dimensional geometric shape of the uppermost cross section of an impact crater.
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.
Catch a Wave: How Waves are Formed
Source Institutions
In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.
Estuaries
Source Institutions
An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.
Plenty on the Plains
Source Institutions
In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent
Making An Impact!
Source Institutions
In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
Ocean in a Bottle
Source Institutions
In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.
Survival of the Fittest: Variations in the Clam Species Clamys sweetus
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi
Stream Table
Source Institutions
In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.
