In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

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

In this activity, learners participate in fun movement activities while playing on a giant game board. Use this activity to get learners involved in physical activity.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity about endoskeletons (page 8 of PDF), learners observe, compare and contrast different kinds of chicken bones, and relate their chicken bone observations to human bones.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.

In this activity about light and perception, learners create and observe moire patterns.

In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

This neuroscience activity introduces learners to how messages are sent and received by neurons. Learners use modeling clay and pipe cleaners to build model neurons.

In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners will explore how the human brain interprets environmental stimuli.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
