10. Continue the Redesign


Students continue to re design and/or make a fancy wind-up for the auto show.

Advance Preparation

  • Continue to make examples of different sorts of decorated wind-ups available.
  • Photocopy  "Assessment: How a Wind-up Works": download below.


  • Wind-ups begun by students in Lesson 9
  • Same materials as were available in Lesson 9


1.      Class meeting: Distribute the wind-ups and invite a few students to share their plans for completing their decorated wind-ups.  Remind students to keep good notes on what they do and the problems they solve.  They will use these in Lesson 11 when they write their "How-to" books.

2.      Complete the redesigned and decorated wind-ups: Observe what students are doing.  Make sure they are keeping both notes and sketches in their science notebooks.

3.      Distribute the unit assessment: "How a Wind-up Works."

4.      Outcomes

  • Students complete their wind-ups and the notes of how they made them.
