6.2: Matter & Energy 3 Dimensions & Progressions

Unit 3

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 help design an experiment to see if adding energy (heating) affects the rate of evaporation. Students will look at molecular animations to help explain why the heating water increases the rate of evaporation. Students will be introduced to a more detailed model of the water molecule. Students will create 3-D Styrofoam models of water molecules.

● Lesson Plan ● 2 Styrofoam balls (1½-inch) ● 4 Styrofoam balls (1 inch) ● 2 fat toothpicks ● School glue ● Permanent marker ● 2 quart-size zip-closing plastic storage bags ● Hot water ● Room-temperature water ● 2 squares of brown paper towel ● 2droppers

Activity: Condensation

● 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 investigate the condensation of water vapor on the inside of a plastic cup. Then they design an experiment to see if cooling water vapor even more affects the rate of condensation. Students

● Lesson Plan ● 2 clear plastic cups ● Room-temperature water ● Ice cubes ● Gallon-size zip-closing plastic bag ● 1 short wide-rimmed clear plastic cup ● 1 tall smaller-rimmed clear plastic cup ● Hot water (about 50 °C) ● Magnifer

also relate evaporation and condensation to the water cycle.
