In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

This activity was designed for blind learners, but all types of learners can use it to investigate how, in a one-celled organism such as a bacterium, the division of cells increases the number of cell

In this fun activity for any size group, early elementary learners complete physical challenges while playing a game. Learners add new challenges to the "wheel of fitness" that they want to try.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this activity (page 32 of PDF), learners investigate the nutritional needs of healthy bones and muscles.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this nutrition activity (page 26 of PDF), learners consider the nutritional needs of people with specific dietary requirements, such as athletes, persons with diabetes and vegetarians, and create a

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity learners will "rescue" animals from tape and then sort the animals. Learners will use science process skills such as categorizing and making observations while they play.

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

In this activity about human anatomy (page 16 of PDF), learners construct a model arm and discover how muscles and bones work together to achieve efficient movement.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

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
