The sun is our nearest star, and all of our energy comes from it. The sun sends out very large amounts of energy every day. We call this energy solar energy or radiant energy. Without the sun, life on earth would not exist because our planet would be totally frozen. We use this solar energy in many different ways. The sunlight lets us see and warms us.
Plants use the light from the sun to grow. They store it as chemical energy. The energy is stored in their roots, fruits, and leaves. This energy feeds every living thing on the earth. When humans and animals eat plants, and the food made from plants, we store the energy in our bodies, in our muscles and in our brain cells.
We use this energy for everything we do. We use energy when we sing a song, think a thought, tell a joke, climb a ladder, make a pizza, or run a race. Everything needs energy!
27. The sun is the farthest star from our planet.
28. Radiant energy is another name of solar energy.
29. Life on earth would exist if there were no sun.
30. Chemical energy is just stored in leaves.
31. Both human and animals eat food made from plants.
32. We store energy in our bodies, in our muscles and in our brain cells.
