This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this outdoor activity, learners design devices that will catch prey or gather plants.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

This simulation helps learners understand what happens to food as it passes through the digestive system.

In this activity, learners are challenged to eat some candy as a cell would need to as well as to think about some of the problems that arise when a cell ingests food.

In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

In this activity and game, learners will train to improve balance and spatial awareness by performing throwing and catching techniques on one foot.

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

In this outdoor activity and animal-role-play game, learners discover and uncover the hidden world of "cryptozoa"—organisms such as spiders, salamanders and slugs that live under objects, like rocks a

In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

In this activity, learners play an active version of freeze tag based on predator/prey relationships.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
