Lesson 3: Classifying Elements
Main Idea: Elements are made up of atoms, which are made up of smaller particles.  Elements can be metals, nonmetals, or metaloids. The periodic table is separated into rows called periods and columns called rows or families. Elements in the same family are related due to sharing similar chemical properties.

Lesson 4: Mixtures
Main Idea: The differences in chemical and physical properties of substances  are used to separate mixtures and identify compounds. 

Vocabulary 

• mixture
  
• suspension
  
• solution
  
• solvent
  
• solute
  
• solubility
  
• filtration
  

Lesson 5: Compounds
Main Idea: During chemical reactions, the atoms in the reactants rearrange to form products with different properties. Differences in chemical and physical properties of substances are used to separate mixtures and identify compounds.
