Hold a Hill
Source Institutions
In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.
Lichen Looking
Source Institutions
In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.
Seismic Slinky!
Source Institutions
Did you know that a Slinky makes a handy model of earthquake waves?
Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.
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.
Seas in Motion
Source Institutions
In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.
Getting There!: Navigation and Trajectory
Source Institutions
In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.
Beach Zonation
Source Institutions
In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.
Salt Water Revival
Source Institutions
In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.
FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
Origami Flying Disk
Source Institutions
In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.
Terrestrial Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.
Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
Rover Races
Source Institutions
In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through
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.
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.
Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.
