Science seeks to understand and explain natural phenomena. Scientists understand things by classifying them. This pertains to living creatures as well as non-living materials.

Non-living materials can be classified into groups depending on contrasting properties. If students have made lists in their Science Journals of the properties of various materials and items they have studied, they can use these lists to extend their knowledge and information about the materials they are studying.
