NGSS MS-PS 1-4 Solids, Liquids, and Gases-Thermal Energy
Worksheet. Students will define thermal energy and explain why gas expands to fill its container. Illustrate and explain the distances between particles in a solid, liquid, and gas. Discuss the difference between kinetic energy and temperature. Hypothesize why as particles move apart, the attractive forces between them decreases. Evaluate the relationship between the transfer of thermal energy and a change in kinetic energy.
