Physical and Chemical Properties- 5th Grade Science Unit

Students will review physical properties and investigate a chemical change in an experiment, comparing and contrasting the physical and chemical properties using a Venn diagram. This can be used as an inquiry lesson to introduce chemical properties. Materials needed: milk and vinegar.

Standards & Objectives

Essential and guiding questions: 
  • What was used to observe the properties of these objects? (senses, measurement tools, magnets)
  • Did you notice any change in the object while it was being observed? (no)
  • Does making observations change the object in any way? (no)
  • What type of change occurs when an object is just observed? (no change)
  • What type of properties can be observed without changing the object into a new substance? (physical properties)
  • Define physical properties. (Physical properties are those properties of an object that can be observed without making any change in the object.
