Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.

Students examine the physical characteristics of the Connecticut River Valley. They analyze maps and pictures, identify physical characteristics of the region, and color in the Connecticut River on a map.

Fourth graders examine the role fire plays in maintaining the physical factors of the scrub ecosystem. They see that world ecosystems are shaped by physical factors that limit their productivity.

Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...

Young scholars construct hot air balloons. In this science lesson, students assemble their own balloon using tissue paper and glue. They time the duration of the flight, record data and calculate team averages.

Students engage in a lesson plan to find the purpose for the forests of Oregon. The role of the forest is researched according to different geographic perspectives. The information is portrayed in graphs and presented by group members to...

Students identify the basic components necessary for biodiversity, the critical and countless benefits of habitats, as well as the serious present and future threats to their ongoing existence.

Students describe vertebrates in terms of observable body parts and characteristics and describe life cycles of familiar organisms. They identify familiar organisms as part of a food chain or food web and describe their feeding...

Students describe how plants and animals depend on each other. They see how living and nonliving environments change over time. They identify ways in which humans have changed their environment and the effects of those changes.

Students investigate how changes occur on the surface of the earth through erosion and glaciation. They observe what happens to salt and iron after they interact with water and vinegar, and analyze what occurs when water is sprinkled on...
