Lesson plan — step by step

  1. 1

    Prepare

    Demos: baking soda + vinegar, steel wool + heat optional.

  2. 2

    Set purpose

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

  3. 3

    Teach

    Walk through 8 slides in order—use talk tracks and questions in presenter notes.

  4. 4

    Formative check

    Demo classification: Observe demos; classify reaction type and evidence.

  5. 5

    Close

    Exit slide; assign optional review of student notes online.
