Something new for our homeschool, we did Layers of the Earth recently and I made this custom puzzle. It’s all built on concentric circles and the hardest part of designing it was probably doing the math to make sure the layers were scaled appropriately.
The left side layer pieces are the simple compositional layers: core, mantle, crust. The crust was too thin, so I left it attached to the main puzzle and just peeking out from under the top layer. The right side layer pieces are the mechanical layers which are broken down a bit more based on how they move. Used Hershey text script in Illustrator to put the layer labels on the puzzle back, I love scoring text like that, it looks so clean and precise.
I “painted” everything by coloring in with watercolor colored pencils and then using q-tips and isopropyl alcohol to blend everything together. Painting is not my strong suit, but I can color with the best of them
