In this interactive activity from the Building Big Web site, investigate dams in distress and decide if they should be repaired, removed, or left alone.

This informational text introduce students to the life cycle and migration of the sanderling, a bird that winters on beaches in the Southern United States and South America but breeds in the Arctic during the summer months. The text is written at a grade four through grade five reading level. This is a PDF containing the informational text and a glossary.

This video segment from Evolution: "Darwin's Dangerous Idea," together with interviews with Daniel Dennett and James Moore, depicts Darwin struggling with publicizing his revolutionary theory.

In this video segment adapted from NOVA, scientists search for carbonized remains of plants preserved in lava flows to find out how long it has taken rain forests on Hawaii to regenerate after a volcanic eruption.

Without the work of decomposers, living organisms would eventually use up all the raw materials in the environment, and dead organisms and wastes would pile up. This video segment from Interactive NOVA: "Earth" describes the role of decomposers as the earth's great recyclers.

In this life science-focused activity, students will pretend to have internships as environmental scientists as they research why exactly water is essential for life. They will collect and analyze data to help them calculate about how much water they use on a daily basis and consider where cuts can be made. Following the virtual experience, students will calculate approximately how much water each person would need per day to survive on Mars. They will consider how much of this water could be reused, and they will determine how much water the people on Mars need to survive until the shuttle returns from Earth. Student groups will ultimately develop a plan that maps out water use until the shuttle returns, and they will review each other’s ideas as they search for the most efficient and realistic plan.

Estimated time required: 2-3 class periods.
