Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

Learners take on the role of environmental engineers as they design water filters.

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

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

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.

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

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.

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 activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

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

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

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin
