Title: Everything Is Made of Something
Time: 1 class period
KERA Goals: 2.3
Objective: The students will understand the natural resources that the earth holds.
The Earth is a huge storehouse. It holds the water and food that plants need to grow. It has a great supply of other natural materials. Materials people use are called natural resources.
Natural resources are useful materials found on and under the Earth's surface. You use a variety of natural resources everyday. Food is a natural resource-- so is water. Other resources include soil, trees, and minerals.
Natural resources can be a solid, a liquid or a gas.
Some natural resources are not alive, like most rocks, water and air. These natural resources are called inorganic.
Some of our natural resources are alive, like plants and animals. They are called organic. Something is organic if it can grow and die.
Almost all of the food we eat is organic, because it came from things that were alive.
Inorganic natural resources have many special uses. Rocks that have special uses are called minerals.
Minerals occur all around us. When there is a lot of a special mineral in one place, the mineral is called ore.
Coal is a natural resource used to produce electricity.
Can you think of something that is not made from our natural resources?
Other natural resources are hidden in this word search. Can you find them?
