3 ) Examine matter through observations and measurements to identify materials (e.g., powders, metals, minerals, liquids) based on their properties (e.g., color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, solubility, density).

4 ) Design and conduct an experiment to determine changes in particle motion, temperature, and state of a pure substance when thermal energy is added to or removed from a system.

[SC2015] PS8 (8) 5 :
5 ) Observe and analyze characteristic properties of substances (e.g., odor, density, solubility, flammability, melting point, boiling point) before and after the substances combine to determine if a chemical reaction has occurred.

Title: The Transfer of Energy 3: Rust and Corrosion

This lesson is the third of a three-part series on energy transformation. All three lessons have the general purpose of increasing students' understanding of energy transfer, its role in chemical change, and the factors that can influence this change. This lesson reinforces students' understanding of thermochemistry and electrochemistry by exposure to a process that they observe in everyday life. Through a practical experiment, this lesson allows students to understand how energy transfers during the chemical changes that occur in the rust and corrosion process and the factors that can influence these changes.
