Temperature Changes Everything
Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...
Curated OER
Hot Stuff
Students investigate if heat can change the form of matter. In this physics lesson, students use heat sources to observe the changes in an ice cube. Students graph which heat source changed the matter the fastest.
