Understanding Mixtures: Properties, Changes, and Separation Techniques

In this lesson, students will explore the concept of mixtures, identifying their physical and chemical properties through precise observation. Examples of mixtures will be shared, alongside methods for their separation. Students will learn to recognize evidence of physical and chemical changes, such as color changes or the formation of bubbles. Additionally, they will engage in hands-on activities to analyze mystery mixtures, documenting observations and following laboratory guidelines while ensuring a clean and safe workspace.

Presentation Transcript

  1. Warm-Up • Explain what a mixture is and give a few examples. • Explain how to separate a mixture. • Copy this question onto your yellow sheet and answer in complete sentences.

  2. Learning Target • I can use precise observation skills to describe the physical and chemical properties of substances.

  3. Physical Changes • Evidence Includes… • Smell • Grain size • Color • Texture • Shape • State (liquid, gas, solid) • Density (boiling and melting)

  4. Chemical Changes • Evidence Includes… • Bubbles • Corrosive • Flammable • *Reacts with other substances

  5. Chemical Reactions • How do you know when a chemical reaction has occurred? • Color Change • Explosion • Change in Size • Bubbles & Fizzing • New Smell • Combustion • Change in Temp.

  6. Naming Chemicals • Chemical Name: Sodium Chloride • Chemical Formula: NaCl • Common Name: table salt

  7. Mystery Mixture Data Collection • Physical Properties • Dry Observations • 1. • 2. • 3. • 4. • 5.

  8. Chemical Properties • Mixing with Water-Wet Observations • 1. • 2. • 3. • 4. • 5.

  9. Lab Guidelines Review • Stay with your group. • Stay on task. • Quiet voices. • Follow instructions. • Clean-Up Carefully • Your group will have to be dismissed by Mrs. Alegado. Everything has to be cleaned up and you need to be sitting down and quiet to be dismissed back to class. Walk across the hall quietly!
