Spinning Tops and Centripetal Force










Topic:
 Spinning Toy Tops
Project: Creating a Toy Top to learn about centripetal force and color mixing
 Academic Area/Skills: Art, Design, Science
Materials: Old CDs, Marbles, Bottle Caps
Grades: K+
Friday was such a hit in STEAM Lab! I began the lesson by playing with a Bayblade toy I found at the local dollar store. We discussed how the toy was working and why it was able to stay upright when spinning. This allowed me to bring up centripetal force and explain how it allowed the top to stay upright. We then began creating our own toy tops! I also challenged the kids to design a top that looked 2 different colors when still, but created a new color when spinning. I reviewed some color mixing with the younger grades. 
To make the top, students started with a CD that had a blank label placed on top. They colored a design of their choice. Next, they chose a marble and I helped hot glue the marble to one side and a recycled cap to another. Once dry (just a few seconds), students began spinning away! They tried their top on linoleum, concrete, glass, and carpet to see how different surfaces affected their spin.
