Design a top that can spin for a long time.

","materials","

For the class, prepare:

Process Grid
Clay or Play Dough
Pencils
Small Paper Plates
Paper Clips
Stopwatches

For each student, prepare:

Process Grid

","preparation","

Have all materials ready and accessible to students.

","worksheets","multimedia","steps","

Ask students: “What do you know about mechanical engineering?”
- Write down the brainstorm ideas on a whiteboard or projector.
- Show them pictures of vehicles, machines, etc., and have them guess what they have in common.
- Explain the objective of the day. Show them different tops to start the thinking process
For younger students, bring in some tops of different shapes and play with them together, talking about how they spin and balance. Sinning tops can be tricky, take your time.
Show the students the materials. Don’t give them any details on how to design their top. Have them brainstorm with a partner what they might do.
Add some of their ideas to the process grid. (K-1 – You can tell them that they need to poke the pencil through the plate to make it spin, but don’t tell them where to poke the pencil. Let them experiment with putting the pencil in different places and talking about balance with them.)
Ask questions as they begin designing. Remind students to write their ideas to their Process Grid.
When students are ready, have them go to the “testing area” and time how long their top spins. Record results on sticky notes. Have them go back and redesign to make it spin longer.
Ask students how their tops performed during testing. Allow students to share ideas on what they can improve.
