Lesson Idea 5: 3D Print Spinning Tops

Domenico_DDomenico_D Member, Onshape Employees Posts: 59 EDU

Happy Wednesday everyone! Here is a fun idea to design at home and then 3D print. I'd love to hear how you plan to teach remote/hybrid classes with hands on components.

Curriculum Idea: Students design, 3D print, and test spinning tops

Topic area: Design for 3D printing, Physics

Description:  Assign students the task of designing and 3D printing tops. You could start by having the students play with some real tops you bring into the classroom or that they have at home and have them create models of their own design. Then, have students 3D print their own tops and test them out to see how long they spin. You could have a prize for the top that spins the longest. 

Concepts of center of gravity, momentum and angular momentum could be explained as well.

Learning Objectives: After completing this project, students should be able to:

  1. Create conceptual designs
  2. Describe how center of gravity and angular momentum affect how a top spins
  3. Test their own designs

Models: Link to Spinning Tops Model
