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).

[SC2015] PS8 (8) 4 :
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
URL: http://sciencenetlinks.com/lessons/the-transfer-of-energy-3/
Description: 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.

Title: A Matter of State
URL: http://sciencenetlinks.com/lessons/a-matter-of-state/
Description: The purpose of this lesson is to help students understand that particle movement changes as a substance changes from one phase to another phase. This lesson helps students begin to move from the fundamental concept of solid, liquid, and gas to the reasoning for why the states exist under given conditions.

Title: Temperature Changes Everything
URL: http://sciencenetlinks.com/lessons/temperature-changes-everything/
Description: In this lesson, students will determine the effect of temperature on the motion of particles. The primary purpose of these activities is to introduce the students to the concept that temperature causes molecules and atoms to move faster and farther apart, which in turn causes the change from solid to liquid and liquid to gas. Students need to come to this activity with the knowledge that some solids turn into liquids when heated. They also need to understand the observable differences between a solid and a liquid.
