The world is made up of both living and non-living things. This unit helps students explore the important differences between the two. The term "living thing" refers to things that are now or once were alive. A "non-living thing" is anything that was never alive. In order for something to be classified as living, it must: grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria. Living and non-living things interact with each other all the time.
