Changes in the Copper Penny
Third graders explore the difference between a physical change in a substance and a chemical change. students study the volume, density, altering shape and chemistry of a copper penny.
Curated OER
Experimenting with Physical Changes
Fourth graders explore physical changes. They discuss that physical change is a change in size, shape, or state of matter of a substance. Students explore what change takes place when two substances can dissolve each other. They observe...

Physical Changes of Matter
Students solve a mystery using evidence gathered during a science investigation. In this physical changes lesson, students analyze a note written in marker to determine the physical changes the ink from the pen underwent. Students...
Curated OER
Chemical Change vs. Physical Change
In this physical and chemical change activity, students are given a description of these changes. They are given ten changes that the students identify as chemical or physical changes based on their reading.
