Collect Invertebrates to Determine Water Quality
Source Institutions
This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

Balloon Impacts
Source Institutions
In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

Kid Moon: Splat!
Source Institutions
In this activity, learners model ancient lunar impacts using water balloons.

Tabletop Biosphere
Source Institutions
In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.

Salt Water Revival
Source Institutions
In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

Habitats of the Pond
Source Institutions
In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.
Effects of Solar Radiation on Land and Sea
Source Institutions
In this activity, learners explore the different heating properties of soil and water.

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.

Hold It
Source Institutions
In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a

Sink or Float
Source Institutions
In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

Pop Rockets
Source Institutions
Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Soil Density
Source Institutions
In this activity, learners will test soil content using their sample, some water and a container that seals.
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.

Make Your Own Ant Farm
Source Institutions
In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.

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.

Scent Tracking
Source Institutions
In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

Silent Stalking
Source Institutions
In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.
