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).

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

Learners use beach profile data from a local beach or online data from Ocean City, Maryland to investigate coastal erosion and sediment transport.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

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 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.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

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 build a wind turbine and test it to see how much energy is created.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.
