4:
Structure and Properties of Matter

Objectives:

1. Matter has characteristic properties, such as boiling points, melting points, and density, which distinguish pure substances and can be used to separate one substance from another. Matter includes 1) substances classified as either elements or compounds, and 2) mixtures classified as either homogeneous or heterogeneous.
   1. States of matter (solid, liquid, gas)
   2. Phase changes (melting, freezing, boiling, evaporation, condensation, sublimation)
   3. Classification of matter: substances vs. mixtures
   4. Compare and contrast solutions, colloids, and suspensions
   5. Physical vs. chemical properties and changes
   6. Law of conservation of mass

Time Range:
4th Quarter; 35 days for 4.A, 4.B, and 4.C

Suggested Teaching Strategies:

• Introduce terms and principles of solubility through demonstrations (sugar & water, salt & water, etc.).
• Compare and contrast differences between saturated, unsaturated and super saturated solutions.
• Have students use a variety of substances to determine their physical characteristics such as boiling point/melting point, etc.
• Use a variety of materials to demonstrate the differences of elements, compounds, and mixtures.
• Demonstrate chemical and physical changes using the mini lab "What are some indications of changes?"
• Identify chemical change by observing a variety of mini-demonstrations.
• Reinforce student understanding of physical properties of substances using a variety of worksheets and activities.
