This document outlines key concepts about the mix and flow of matter for an 8th grade science class. It discusses pure substances and mixtures, including solutions. It also describes solubility, saturation points, and the particle model of matter. Additional concepts covered include properties of fluids, viscosity, density, mass, volume, pressure, and buoyancy. Students are directed to additional online resources for more information on each topic.

3. Key Concept Two
• Pure Substances: one component. For
more info: definition of pure substance
• Mixture: two or more substances. For
more information: definition of mixture
• Solutions: can be heterogeneous or
homogeneous. For more information:
definition of solutions

4. Key Concept Three
• Solute and solvent:
• a solute is the substance that is
dissolved
• a solvent does the dissolving
• For more information: explanation of
solute and solvent with picture

5. Key Concept Four
• Solubility: the amount of solute that can
be dissolved in a solvent
• Saturation points: the point at which
the solvent can hold no more solute
• For more information: Solubility and
saturation explanation

6. Key Concept Five
• Particle Model of Matter: Explains the
states of matter (solid, liquid, gas)
• For more information: Explanation and
pictoral representation of Particle Model of
Matter

7. Key Concept Six
• Properties of Fluids: Fluids have many
properties. To see some examples:
Properties of fluids examples

8. Key Concept Seven
• Viscosity: the thickness of a liquid
• Viscosity and flow rate: the viscosity of
a liquid can affect how the liquid flows.
For more information: viscosity and flow
rate

9. Key Concept Eight
• Mass: is equal to density X volume
• Density: is equal to mass / volume
• Volume: is equal to mass / density
• Density Triangle

10. Key Concept Ten
• Pressure: The Force per Unit Area. For
more information: Pressure

11. Key Concept Eleven
• Buoyancy: Archimide’s Principle: A
solid object will sink in a fluid, if it’s
density is greater than the fluid’s
density, and will float if it’s density is
smaller. For more information: Buoyancy
