Natural Resources

在B站看见了一个系列视频，据说是美国小学生的自然科学课，刚好拿来学一学英语。下面是做的一些笔记以及自己尝试的一些描述。

There are many natural resources. We use natural resources in different ways every day.
Air and water are natural resources. People need clean air and water to live. We need to breathe clean air and drink clean water to keep healthy. Dirty water and air are harmful for us.
Oil is another natural resource. Oil helps a car move and cars help people travel.
Minerals are also natural resources. Minerals come from rocks and soil. Gold, silver, and copper are minerals. Gold is the color of the sun. Silver is shiny gray and copper is orange.
Wood is also a natural resource. Wood comes from trees. We can use wood to make paper.

Natural resources mean something people can use from natural. Such as winds, water, woods, soil and animals. Some natural resources, like minerals, are nonliving resources, they will not grow again.
A mineral is a type of natural resource. It comes from rocks and soil, and can be made to other things.
Golds, silvers and coppers are kinds of mineral. Silvers are more expensive than coppers, and golds are the most precious. All of them can use to transform electronics, but coppers are the most common because of the lowest price. Silvers usually use to make cups, knives, and forks. Golds usually use to make rings that people wear. Gold is shiny yellow, like the sun's color. Silver is shiny gray, and copper is orange.
Sometimes the way people use natural resources is harmful to the environment. That will cause dirty air and water. We should find a clean way to use those so that we can get a cleaner world.
