Particles of Matter: From Macro to Subatomic

Introduce the particle model, pure substances vs mixtures, and how evidence supports subatomic structure (A-GO1).

Lesson plan — step by step

  1. 1

    Prepare

    Prepare demo materials: salt, water, iron filings, sulfur (do not heat yet).; Open PhET States of Matter or similar for optional extension.

  2. 2

    Set purpose

    Display learning-intent slide; clarify success criteria and POS tags.

  3. 3

    Teach

    Walk through 10 slides in order—use talk tracks and questions in presenter notes.

  4. 4

    Formative check

    Evidence vs opinion: Think-pair-share: What observation would convince you matter is made of particles?

  5. 5

    Close

    Exit slide; assign optional review of student notes online.

Materials

  • Prepare demo materials: salt, water, iron filings, sulfur (do not heat yet).
  • Open PhET States of Matter or similar for optional extension.

General outcomes

A-GO1

Specific outcomes

  • A-GO1-SO1
  • A-GO1-SO2

Teacher overview

Establish that chemistry explains matter at the particle scale and that scientific models change with evidence.

Before class

  • Prepare demo materials: salt, water, iron filings, sulfur (do not heat yet).
  • Open PhET States of Matter or similar for optional extension.

Common misconceptions

  • Students may think atoms are like tiny solid balls with no internal structure.
  • Students may confuse physical mixing with chemical bonding.

Formative checks (classroom)

  • Evidence vs opinion

    Think-pair-share: What observation would convince you matter is made of particles?

    Look for: References to reproducible evidence, not authority alone.
