In this learning module, students are involved in an observational study of air pollutants in the atmosphere. The students collect and examine air quality and weather data, looking for correlations between weather and air quality. They discover through their observations that certain atmospheric conditions, including high pressure, clear skies and little or no wind create the conditions for poor air ... Full description.

In this lesson, students investigate the habitats of local plants and animals and explore some of the ways animals depend on plants and each other. They will observe living organisms in a local ecosystem and create detailed drawings and descriptions of them. The final section of this lesson offers a few Internet resources to extend the ideas of this lesson and give students opportunities to observe ... Full description.

This lesson shows students that living things can be sorted into groups in many ways using various features to decide which things belong to which group and that classification schemes will vary with purpose. This lesson is the second of a two-part series on classification. It exposes students to the idea that a variety of plants and animals (organisms) can be classified into one or more groups based ...

In this lesson, students investigate the living creatures in a drop of pond water under magnification. This lesson is the second in a two-part series on microorganisms. It is designed to follow the first lesson, but can also stand alone. Students observe microscopic organisms found in pond water using a hand lens, 30x magnification, and 100x magnification. Observing these organisms should stimulate ... Full description.

This set of activities is designed to help students understand water pollution and its potential effects on human and wildlife habitats. They will understand that pollutants can be divided into three groups: chemical, thermal, and biological. Learning objectives include identification of two or more pollutants in a bog, marsh, stream or other wetland area, using words and art to relate a message about ... Full description.

This activity will promote an awareness of environmental issues and ways that each student can help to improve our Earth. Research will be done by students on a variety of topics and they will create a book about the environment, which includes an index. When the activity is finished, students should be aware of the condition of our environment and what they can do to help improve it. This activity ... Full description.

In this activity the students will be making a model of a polar bear and describing the color of the fur and skin to understand why the color is important. Measuring the temperature of a black sock and a white sock and comparing temperatures is also included in the activity so that the students can understand the difference in heat retention. Students will then look up the word adaptation in dictionary, ... Full description.

While engaged in this activity students will discover that oil spills can impact the entire food chain. They will investigate the effects of oil on various materials, simulating the skin and/or coats of Antarctic marine organisms, and compare the ability of different techniques to clean up oil spills. Oil-coated birds whose feathers can no longer hold air or repel water, and furred ocean mammals such ... Full description.
