Shapes and Colors and Textures, Oh My!
Source Institutions
This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

BioBlitz
Source Institutions
In this activity (on page 2 of the PDF under GPS: Biodiversity Activity), learners will pair up and take a notebook outdoors to a selected location to observe and record a list of living things that t
What Causes Rainbows?
Source Institutions
In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

For the Birds
Source Institutions
In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

Cactus Wheel
Source Institutions
In this outdoor activity/field trip, learners explore the concept of population density.

Stargazing
Source Institutions
In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

Measuring Wind Speed
Source Institutions
In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

Sawing Away
Source Institutions
In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

Animal Diversity
Source Institutions
In this outdoor activity, learners find, count and compare as many different kinds of animals as they can find in two different areas: a managed lawn and a weedy area.

Damsels and Dragons
Source Institutions
In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.

Flocking for Food
Source Institutions
In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

Tree Tally
Source Institutions
In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.

Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Bean Bugs
Source Institutions
In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

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.

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 a Hill
Source Institutions
In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

Feeding Facilitation: A Lesson in Evolution and Sociobiology
Source Institutions
This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

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.
