FOSS Module Summary

Module Summary – Mixtures and Solutions (CA Ed.)


Chemistry is the study of the structure of matter and the changes or transformations that take place in it. Learning about the makeup of substances gives us knowledge about how things go together and how they can be taken apart. Learning about changes in substances is important for several reasons: changes can be controlled to produce new materials; changes can give off energy to run machines. The Mixtures and Solutions Module has four investigations that introduce students to these fundamental ideas in chemistry.


  • Gain experience with the concepts of mixture and solution and the physical properties of substances that are used to identify them as mixtures and solutions.
  • Gain experience with the concepts of saturation and supersaturation.
  • Identify properties of common solid, liquid, and gaseous substances.
  • Understand that during chemical reactions, atoms rearrange to form products with different properties.
  • Learn that all matter is made of very small particles called atoms and that atoms combine to form molecules and compounds.
  • Know that the 90 naturally occurring elements and their combinations account for all the varied types of matter in the world.
  • Understand that the periodic table organizes the elements by their chemical properties.
  • Plan and conduct simple chemical investigations.
  • Use measurement and appropriate tools in the context of scientific investigations.
  • Record data, develop scientific evidence, and draw conclusions from that evidence.
  • Acquire vocabulary associated with chemistry and the periodic table.
