The Squeeze Box
Source Institutions
In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.
Investigating the Uses of Backyard Bacteria
Source Institutions
The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.
Gaming in the Outdoors
Source Institutions
In this set of outdoor games, learners increase their awareness of the outdoor environment by going on a scavenger hunt and an out-of-place hunt.
Map That Habitat
Source Institutions
Historically, sea floor mapping (bathymetry) was done by soundings.
Number of Mentos vs. Height: Soda Geyser Series #5
Source Institutions
In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.
Soda Brand vs. Height Experiment: Soda Geyser Series #4
Source Institutions
In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.
Wind Power: Creating a Wind Generator
Source Institutions
This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.
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.
Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.
Ice on Mars
Source Institutions
In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.
Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
Litter Critters
Source Institutions
In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.
Follow the Scent
Source Institutions
In this outdoor, sensory activity, learners role play as animals trying to identify their "family's" scent and locate their "territory." Learners mark their territories and sniff out other territories
Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).
Mystery Marauders
Source Institutions
In this outdoor, mystery-solving activity, learners work like detectives, gathering evidence to identify the culprits that are attacking plants.
Small Habitats
Source Institutions
In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).
Logs to Soil
Source Institutions
In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.
Trail Construction
Source Institutions
In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
