Great Ice Cube Race With a partner discuss how you can melt an ice cube in a zip lock snack bag at your desk/table the fastest?

Activator Explain how you differentiate between solids, liquids, and gases?

Solid Definite Shape, Definite Volume Molecules are packed together, physically attached and vibrate in place ≤ -1°C for H2O

Solid to Liquid Molecules are moving as fast as they can as a solid Physical bonds break one by one Molecules break loose and fall to the bottom as liquid molecules 0°C for H2O

Liquid Variable Shape, Definite Volume Molecules are in contact, but not physically attached. In bottom of container rolling and sliding over each other. Molecules move faster as they are heated. 1°C - 99°C for H2O

Liquid to Gas Liquid molecules are moving as fast as they can Molecules separate from each other and bounce around wildly 100°C for H2O

Gas Variable Shape, Variable Volume Molecules are flying around the container and bouncing off of each other ≥ 101°C for H2O

Plasmas 99% of the matter in space is a plasma Ex. Stars, Lightning Superheated gas molecules that are moving so fast that their electrons have stripped off.

Summary What is the difference between solids, liquids and gases in terms of molecular motion? Write a thorough, thoughtful paragraph with complete sentences.

Activator Describe the molecular motion of a solid Describe the molecular motion of a liquid Describe the molecular motion of a gas

Writing Assignment Write a story in first person where you are a water molecule at -20°C, 0°C, 50°C, 100°C, 150°C, and 25,000°C. Write an introduction and a paragraph for each temperature. Be sure to describe your molecular motion at each temperature and end with a summary paragraph.
