Water is the great architect of Earth and a defining factor for the location and movement of life on this planet. Without water, our world would look very different; without the watersheds which capture, coalesce, move, and recycle water throughout a natural system, human and wildlife habitats would not be the same. Freshwater rivers, streams, and lakes are some of the most heavily utilized and pressured natural systems on the planet; these critical habitats have taken the brunt of negative human actions for years. Now, more than ever, we must learn to safeguard our watersheds for the protection of all life that depends on them.For more information and classroom activities, please visit The Wildlife Center of Virginia and VPM UNTAMED websites. 

Short Description: This is an inquiry investigation, geared toward student use of outdoor schoolyard sites. Its focus is to have students applying what they've learned about the scientific method and experimental design, gathering quantitative evidence to support hypotheses.

This article highlights science lessons about mammals, mammal diversity and adaptations, and polar mammals. Literacy integrations and alignment to national standards are included.

This activity is a field investigation where students will compare the biodiversity of two separate habitats based on the collection and identification of insects.

As 3rd grade students have been learning about History SOL 3.13 - this lesson integrates the content that American people have different ethnic origins and come from different countries (immigration) as well as the reading strategy of reading the author’s words and determining whether the information is directly stated (right there) or inferred based on clues from the author’s words.

Students learn about endangered species and actions humans have taken to address the issue of endangered species. The Xpeditions lesson has students think about their experiences with zoos, learn about the reasons for captive breeding, and come up with an opinion about the role of zoos and aquariums in addressing this issue. The additional activity in the Teaching Materials section has students learn about a controversy within the scientific community regarding the captive breeding of tigers. Students will read articles written by the scientists, develop an opinion, discuss the issue with their classmates, and draw a conclusion based upon additional information they have researched.

Students perform a macroinvertebrate survey to gauge the health of a local river. They collect water samples and count macroinvertebrates to learn how the health of a river's ecosystem can be determined by its river insect population.
