Classification of Matter

Author: carolyn fruin

I know I have mastered these learning targets when

  • Using data collected about the physical and chemical properties of a substance, I can classify the material as a compound, element or heterogeneous or homogeneous mixture.
  • I can predict how something will behave when I expose it to certain outside forces or chemicals.

Learning Targets

  • I can classify different types of matter (element, compound, heterogeneous mixture, homogeneous mixture).
  • I know the difference between physical vs. chemical properties and can state examples of each.
  • I know the difference between physical vs. chemical changes and can state examples of each.
  • I can identify matter & changes in matter based on physical and chemical properties or changes.

General Vocabulary


There are many ways that matter can be classified. The most common way is to look at certain properties of the matter and organize based on grouping those properties.

Matter- anything that has mass and takes up space.

Classifying matter - be sure you understand each of these terms and can identify a sample of material with one of these categories.

  • Heterogeneous mixtures are not well mixed.
  • Homogeneous mixtures are well mixed.
  • Substances cannot be separated by physical methods.
  • Compounds are made up of two or more elements that are chemically combined.
