Description
This lesson explores the states of matter and their properties.

Objectives
Students will:
• Simulate the movement of atoms and molecules in solids, liquids and gases.
• Demonstrate the properties of liquids including density and buoyancy.
• Investigate how the density of a solid behaves in varying densities of liquids.
• Construct a rocket powered by pressurized gas created from a chemical reaction between a solid and a liquid.

Lesson Activities and Sequence

1. Heat As The Agent of Change: Atoms and Molecules in Motion
Students study heat and its effects on spaceflight. (Module from Genesis mission education)
Keywords: matter, heat, spaceflight

2. Liquid Rainbow
Students use salt and food colorings to generate different density water and to create a density rainbow.
Keywords: density, matter, atoms, molecules, mass

3. Potato Float
Students will float an object in varying density solutions.
Keywords: matter, mass, weight, density, solutions

4. 3-2-1 Pop!
Students construct a rocket powered by the pressure generated from an effervescing antacid tablet.
Keywords: matter, rockets, pressure, gas
