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

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

Millions of organisms can live in and around a body of water.

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

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.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

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 cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this activity, learners will reuse plastic bags in an interesting way.

In this matching game, learners study the limits of life on Earth to see what other places in the solar system might sustain microbial life.

Learners work in teams to investigate how scientists use physical characteristics to classify living things.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this activity, learners will plot the distribution of various oozes using information from sediment maps.

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.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.
