EARTH & SPACE SCIENCE-In this module, students investigate weather by exploring the atmospheric systems and interactions that result in "weather." They begin by exploring the angle of sunlight that hits Earth's surface and relating differential heating to changes in weather conditions around the world. Students explore weather systems by observing, measuring, and recording local conditions. They use tools such as thermometers, rain gauges, and barometers to collect data. With that data, students identify and describe weather patterns and make predictions about future weather conditions. Included are investigations of temperature, wind, precipitation, air pressure, humidity, the water cycle, and storm.

BSCS Science TRACKS includes a Teacher's Edition, complete with facsimile pages of the student guide, placed exactly where you need them with the Teaching Strategies. In addition, the Teacher's Edition incorporates the following features, designed to help you organize and manage an activity-based science program within your busy teaching day. The Program Overview explains:

• the general philosophy, goals, and features of the program;
• the relationship of the program to the National Science Education Standards, including the content, teaching, and assessment standards, and Benchmarks for Science Literacy;
• the curriculum framework (scope and sequence)
• the BSCS approach to conceptual development and inquiry using
  • an instructional model,
  • collaborative learning,
  • communication skills, and
  • clearly articulated assessment strategies;
• the structure of the student guide and resource book; and
• the structure of the Teacher's Edition.
