Description: Students will create models for the molecular motion in a solid, liquid, and a gas using a container of beads.
California State Standard(s): SC.8.3.d. Students know the states of matter (solid, liquid, gas) depend on molecular motion. SC.8.3.c.Students know atoms and molecules form solids by building up repeating patterns, such as the crystal structure of NaCl or long-chain polymers. SC.8.5.d. Students know physical processes include freezing and boiling, in which a material changes form with no chemical reaction. SC.8.3.e. Students know that in solids the atoms are closely locked in position and can only vibrate; in liquids the atoms and molecules are more loosely connected and can collide with and move past one another; and in gases the atoms and molecules are free to move independently, colliding frequently.
