In this video segment, ZOOM guest Cassie takes us on a tour of the coral reef near her home in Key Largo, Florida, and points out some of its unique features.

In this example students examine and critique an argument which implies that it is not cost effective to pay for an automobile with increased fuel efficiency. Using a few reasonable assumptions shows that some of the writer's quantitative claims are not very accurate.

This assignment engages students in an environmental history class in the use of quantitative data, and raises questions about the nature and meaning of that data, and how it might be utilized.

In this lesson, students find their location on a map using Latitude and Longitudinal coordinates. They determine where they should go to be rescued and how best to get there.

Student teams design and then create small-size models of working filter systems to simulate multi-stage wastewater treatment plants. Drawing from assorted provided materials (gravel, pebbles, sand, activated charcoal, algae, coffee filters, cloth) and staying within a (hypothetical) budget, teams create filter systems within 2-liter plastic bottles to clean the teacher-made simulated wastewater (soap, oil, sand, fertilizer, coffee grounds, beads). They aim to remove the water contaminants while reclaiming the waste material as valuable resources. They design and build the filtering systems, redesigning for improvement, and then measuring and comparing results (across teams): reclaimed quantities, water quality tests, costs, experiences and best practices. They conduct common water quality tests (such as turbidity, pH, etc., as determined by the teacher) to check the water quality before and after treatment.

This activity is a field investigation of the biodiversity in a given area. The exercise will give students experience making scientific observations and creating a dichotomous key.

This activity is a field investigation where student gather data on organisms they find in or around a pond.

This activity will help students learn about Minnesota animals and characteristics that distinguish them from one another.

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.

In this video segment adapted from Navajo Technical College, meet a dendroclimatologist who studies the relationship between precipitation and tree growth in the Navajo Nation.

In this lab activity, students determine density differences of water samples with varying temperature and salinity levels. Students synthesize information to predict the effects of oil in given water samples.

This video segment from NOVA: A Desert Place describes the physical characteristics and organisms that define the desert biome.

This video segment from Outdoor Nevada examines threats to the desert tortoise population.

Students are challenged to design a permanent guest village within the Saguaro National Park in Arizona. The design must provide a true desert experience to visitors while emphasizing sustainable design, protection of the natural environment, and energy and resource conservation. To successfully address and respond to this challenge, students must acquire an understanding of desert ecology, environmental limiting factors, species adaptations and resource utilization. Following theintroduction, students generate ideas and consider the knowledge required to complete the challenge. The lectures and activities that follow serve to develop this level of comprehension. To introduce the concepts of healthy ecosystems, biomimetics and the importance of sustainable environmental design, students watch three video clips of experts. These clips provide direction for student research and challenge design solutions.

This lab activity allows students to indetify macroinvertebrates and determine the health of an acquatic ecosystem.

This activity is a field investigation where students gather population data on bird species. The students will create bar graphs and interpret their findings. Based on their experiences and data, they will write an answer to the guiding question.

This activity combines field exercise soil collection with lab analysis of soil bulk density. Students develop a lab procedure to measure density and analyze data using Microsoft Excel computer software.

This activity is an introduction to population sampling techniques. Students' will identify weaknesses and strengths of a variety of techniques and determine the best applications of the various methods identified.

This article provides links to web sites that describe the Arctic and Antarctica in terms of geography, climate, and ecosystems.

This video segment from Greater Boston examines whether environmental toxins may be to blame for a rare skin disease.
