The Investigating Matter topic recognizes that to understand their world, students must have many experiences with matter. During this topic, the students:

Define matter and identify many of its common properties.
Become familiar with the common states of matter: solid, liquid, and gas.
Plan and conduct an investigation to prove that air has weight.
Conduct investigations to show that materials can be identified based on their properties.
Show that the weight of matter doesn’t change when heated or cooled or when mixed with other substances.
Discover the differences between physical and chemical changes.
Plan and conduct fair tests involving chemical changes to show that the weight of matter stays the same during these changes.
Discover how unusual mixtures have properties, unlike other materials they explore in the topic.
