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.
Do Your Own Dig
Source Institutions
In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.
Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
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.
Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.
Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
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
Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
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.
Mapping a Study Site
Source Institutions
In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.
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.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
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.
Saguaro Nest Cavities
Source Institutions
This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.
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.
Exploring Ultraviolet (UV) light from the Sun
Source Institutions
In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
