|Mixtures and Solutions Overview
MIXTURES AND SOLUTIONS
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.
FOSS EXPECTS STUDENTS TO
• 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
• Identify properties of common solid, liquid, and gaseous
• 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
• Know that the 90 naturally occurring elements and their
combinations account for all the varied types of matter in the
• 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
• Record data, develop scientific evidence, and draw
conclusions from that evidence.
• Acquire vocabulary associated with chemistry and the
