Habitat Observations
Source Institutions
In this outdoor activity, learners discover the wonders of the habitat surrounding them.

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.

Rockets Away
Source Institutions
In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

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.

Ants
Source Institutions
In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

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.

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.

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.

Cardiac Hill
Source Institutions
In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

The Old White Sheet Trick: Light and Insect Behavior
Source Institutions
In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

Beachcombing
Source Institutions
In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.
Disappearing Water
Source Institutions
In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

Scavenger Hunt
Source Institutions
An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv
Big and Little Cups
Source Institutions
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Determining the Amount of Transpiration from a Schoolyard Tree
Source Institutions
In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.
