  Unit A: Key Ideas

Focus On: Mix and Flow of Matter

This unit has four sections that are dedicated to helping you understand the basics of mixtures and fluids. Each section has a key idea indicated by its title, and each section is divided into lessons. Click each key idea tab to view the lesson titles and some key questions you will investigate.

 
Section 1 Key Idea: Fluids have many applications, but must be used safely.

Lesson A1: ï»¿Using Substances Safely
Key Question – How do we prevent getting hurt when using dangerous fluids?

Lesson A2: A World of Fluids
Key Question – What are some common fluids that we use everyday?
 


Section 2 Key Idea: Fluid and mixture properties can be explained with the particle model.

Lesson A3: Pure Substances and Mixtures
Key Question – What are the different classifications of mixtures?

Lesson A4: Solubility and Concentration
Key Question – How do we compare the strengths of different solutions?

Lesson A5: Solubility Changes
Key Question – How can we make substances dissolve faster?

Lesson A6: The Particle Model and Mixtures
Key Question – How does the particle model explain dissolving?


Section 3 Key Idea: Gases and liquids are affected by temperature and compression.

Lesson A7: Viscosity
Key Question – How does temperature affect the ability of a fluid to flow?

Lesson A8: Density
Key Question – How is density related to the particles in a fluid?

Lesson A9: Buoyancy
Key Question – Why does density affect the ability of objects to float?
