Students make group decisions about matter as they explore and interpret many types.

Tenth graders complete a directed study, form the internet, and then complete activities.

Students working in small groups examine beach sand to discover signs of erosion, weathering, ocean currents and waves. They present their findings to the class.

Students explain that air is everywhere and discuss how living things use air.

Young scholars recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Learners explore how principles of gas behavior relate to diving in order to plan safe underwater activities.

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...
