This activity on physical and chemical changes in matter includes a “gallery walk”, an activity to identify physical and chemical changes in everyday life, and a reinforcement (homework) worksheet.
The first part includes defining physical and chemical change then sending students on a “walk” to identify whether various changes are considered physical or chemical. I printed the “stations” cards in color, laminated them, and cut them apart. I tape them around my classroom in order. After discussing the definitions of physical and chemical changes, the students walk around and write a “P” or a “C” on their answer sheet. We go over the answers, then they begin the second activity.
The second part asks students to read a short story about a person’s chaotic morning that includes everyday examples of physical and chemical changes. They underline the physical changes in one color and the chemical changes in another color.
A reinforcement worksheet is included that can be used as an additional class activity, partner work, or as homework.
