The Confident Chemistry Teacher

Episode 9: Inside the Unit- Matter & Change

Listen Later

In this episode of The Confident Chemistry Teacher Podcast, I’m taking you inside the Matter & Change unit—one of the most important foundations for the rest of the year. This unit helps students:

  • Build vocabulary they’ll use in every future Chemistry topic
  • Practice classification skills through hands-on activities
  • Gain lab confidence while still early in the year
  • See the difference between physical vs. chemical properties and changes

    • I also share how I structure this unit in my own classroom, when I like to teach it in the sequence (sometimes 2nd, sometimes 3rd), and why it’s so valuable for setting expectations and giving students an early win.

    Activities Featured in This Episode

    • Vocabulary T-Charts – Students classify examples and develop their own definitions before we formalize the terms. (🎁 Grab my free T-Chart slides in the show notes!)
    • Matter Worksheet – A quick reinforcement of key vocabulary.
    • Physical & Chemical Properties/Changes Card Sort – Simple, hands-on sorting that builds confidence.
    • “Goody Brittle” Lab – A tasty activity where students identify physical and chemical changes in real life.
    • Matter & Change 8-Station Lab – Students rotate through lab skills while applying new vocabulary (more details in a future episode!).
    • Chromatography Lab – One way I introduce separatory techniques, though I’m still looking for better resources here.

      • Standards Connections: 

      • HS-PS1-2: Construct and revise explanations for chemical reactions using atomic and molecular structures.
      • HS-PS1-3: Plan and conduct investigations to gather evidence of physical and chemical properties.

        • Science & Engineering Practices:

        • Modeling, analyzing data, and constructing explanations.

          • Crosscutting Concepts:

          • Patterns, cause & effect.
