One word for many things.
Energy is the reason things move, glow, make sound, do work, and grow warmer or cooler.
↳ No energy, nothing happens.
Look for the five signs.
↳ Each sign means energy is at work.
Our biggest giver.
The Sun gives light and heat. Clothes dry, papads dry and plants grow because of it. Nearly every living thing here depends on it.
↳ Life on Earth runs on sunlight.
Why you can run.
Food is a source of energy. It lets us move, work and play. Without a meal we soon feel tired.
↳ Every living thing eats for energy.
Animals too.
A dog runs, a kite flies and a fish swims. Each of them gets its energy from the food it eats.
↳ Food is the fuel of living things.
Burnt to give energy.
A fuel is something burnt to give energy. Petrol and diesel run vehicles. Cooking gas, wood and coal give heat for cooking.
↳ Fuel is to a machine what food is to us.
Energy makes things move, light up, make sound, do work and change how warm they are. Simple activities with a balloon, rubber bands and sunlight show it at work.
