6.2: Matter & Energy 3 Dimensions & Progressions

Unit 3

●​ Hot water (about 50 °C) ●​ Magnifier

Activity: Freezing

Objective

Overview

Materials

●​ I can predict the effect of heat energy on states of matter. ●​ I can design and carry out an investigation comparing heat and matter.

●​ Students will mix ice and salt in a metal can to make it very cold. They will then see liquid water

●​ Lesson Plan ●​ Empty clean metal soup can ●​ Salt ●​ Ice ●​ Metal spoon or sturdy stick ●​ Teaspoon ●​ Paper towel ●​ Pliers ●​ Duct tape

and ice form on the outside of the can. Students will watch an animation of water molecules arranged as ice.

Activity: Melting

Objective

Overview

Materials

●​ I can predict the effect of heat energy on states of matter. ●​ I can design and carry out an investigation comparing heat and matter.

●​ Students will see a small piece of ice melt on an aluminum surface. Students will explain the energy transfer and molecular motion which cause the change in state from a solid to a liquid. Students will see and discuss an animation of ice melting and compare the state changes of water to the state changes of other substances. They will also investigate sublimation of dry ice through a teacher

●​ Lesson Plan ●​ 2 small pieces of ice ●​ 2 small clear plastic cups ●​ Water ●​ Ice ●​ Dry Ice ●​ Brown paper towel

●​ Cold water ●​ Hot water
