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

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

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 ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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 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 activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

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

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

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.
