Interviews about energy with children, scientists , and people on the street reveal the wide range of concepts that teachers encounter. In this session, you will look at the difference s between the everyday language of energy and the scientific concept, see highlights of its history, and learn its importance in our understand ing of the world.

Scientists define energy as the ability to do work. In this session, see how work is defined in physics and examine how energy and work are related.

Change happens when energy is transferre d or converted. In this session, examine conversion between potential and kinetic energy. Through examples, see how events that involve a small amount of energy can trigger much larger events.

Energy can be seen in cycles every day, from the bouncing of balls to the swinging of pendulums. In this session, further explore the relationsh ip between kinetic and potential energy to understand how cycles begin and are sustained, and why they decay.

All life forms use energy. In this session, explore the transfer and conversion of the potential energy in food, and see how that energy is stored. Through animations , witness photosynth esis, the process by which plant cells capture the ultimate energy source for all food — sunlight.

Physicists use the concept of a system to trace and quantify the flow of energy. In this session, take a close look at a number of energy systems and see how this concept is closely linked to the Law of Conservati on of Energy.

A machine's energy output cannot be greater than its input. In this session, look at the energy that goes into useful work, examine how some always ends up as heat, and see why systems are never 100% efficient.

Energy lights our homes, fuels our transporta tion systems, and much more, but affordable energy is in limited supply. In this session, look at the global impact of these limits and see how being smart about using energy will become more important in our daily lives
