kinetic molecular theory (kmt)
Unit 1 Overview
Students will learn about the the hazards chemicals pose to the people who use them while learning about states of matter and kinetic molecular theory. First, students examine physical properties and hazards of substances and mixtures. Next, students examine how different gases respond to temperature changes and how different concentrations of salt water respond to temperature changes. Students engage in collaboration, analysis of data through board discussions, and writing an analysis using claim-evidence-reasoning. Using a phet simulation, students then model what happens to particles during increase and decrease in energy. Students then investigate thermal transfer through a water mixing lab. Finally, students engage in an ice cream engineering activity to examine how different substances in similar conditions can have different properties with may be harmful or beneficial.
