In this unit, students trace matter and energy through a flame when ethanol burns, building foundational concepts and practices. The Carbon-transforming process addressed in this unit is combustion. The Organism Scale units Animals, Plants, and Decomposers engage students in tracing matter and energy through organisms e.
These units address the same big ideas in different contexts, focusing on the processes within an individual organism. The Carbon-transforming processes addressed in these units are photosynthesis, cellular respiration, digestion, and biosynthesis.
The Large Scale units Ecosystems, Human Energy Systems engage students in tracing matter and energy through larger systems. At the large scale, students trace matter through carbon pools e. The beginning teacher understands the principles of electricity and magnetism, and their applications e. Refer to Competency 41 for a description of the four fundamental forces.
The University of New South Wales offers a variety of animations and information on electric motors and generators , the right hand rule, and practical applications such as loudspeakers. The animations include graphs showing current variations of mechanical devices. The beginning teacher applies knowledge of properties of light e. View this diagram to see the electromagnetic spectrum with references to radiation type and wavelength, and recognizable objects for scale, frequency, and temperature.
The chapter includes EM activities. Michael Fowler of the University of Virginia Physics Department describes the history and science behind determining the speed of light in this short lecture manuscript.
