### In the lessons

In science, the Sun is our main source of light and heat; a battery is a power source; food is a source of energy and vitamins (oranges are a source of vitamin C). In geography, the source of a river is where it starts, often in hills or a spring; the mouth is where it ends. In history and research, children check sources to see if information is true; primary sources come from the time itself. Phrases: source of, light source, energy source, reliable source, primary source.
