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