In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

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.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this activity, learners make plaster casts of an animal track to learn more about animals and animal behavior.

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.

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.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.

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.

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.

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

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.

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.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

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.

In this outdoor activity and game, learners roundup a "herd" of hopping insects and find out how many different kinds or species are in their herd.

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.

In this outdoor activity that can be combined with a hike, learners try to match a "mystery community" by shaking animals out of different trees and shrubs.

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
