Changes All Around Us
Sixth graders, in groups, observe the difference between physical and chemical changes and create a collage of pictures to show the difference.
Curated OER
Stomach Chemistry
Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.
Curated OER
Properties of Materials - Part B
Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.
