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. 

Today, over six billion people live on planet. This means that there are very few places on Earth with no people. One place that has very few people is at the bottom of the Earth. In Antarctica, you will not live there all year round.

     Frist, Antarctica is the coldest place on Earth. For example, it can be minus 130 degrees in the winter Human cannot live in this kind of environment. Because it is so cold, very few plants and animals live there. This means there are no farms and no places to find wild plants and animals to eat. In order for people to live in Antarctica food must be sent there on boats, and this is expensive.

     Another problem is that Antarctica can be dangerous . Many people think it is safe to travel for Antarctica in the summer months when it is warmer However. Antarctica is mostly ice, so when it is summer, the ice melts.When the ice melts, it can break, so people cannot travel around Antarctica during the summer. If the ice breaks, they could fall into the water and die. Antarctica is a tough place to live.
