Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
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 test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
Learners construct an electricity-generating wind turbine out of a plastic bottle.
Learners take on the role of environmental engineers as they design water filters.
In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.
In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.
In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.
In this activity, learners use whale count data from the Hawaiian Islands Humpback Whale National Marine Sanctuary to compare whale counts in relation to environmental factors.
This activity has three story puzzles learners can solve to learn about life in the Arctic.
In this Bob the Builder(TM)-themed activity, learners go on a nature walk outside and describe what they observe using their senses.
This activity introduces learners to Native Americans as people who depended upon nature in the past and continue to emphasize the importance of nature in the present.
This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.
