In the the after-school tech club we teach CAD design with Tinkercad.
We usually start with the wrench tutorial, then do a box with a lid to
teach measurement and dimensioning, then the penguin to introduce
rounded geometries, and after that, the sky is the limit.

I was asked to do a STEM-type activity on the theme of pumpkins
for the october 2026 Science Saturday at the
Santa Fe Children's Museum.
I decided to build a balance
where kids would be on one side, and pumpkins on the other.
I made 2 dishes, and
a frame in the shape of a tetrahedron, consisting of 4 poles and 2
cords. When balanced, the dishes are only a few inches off the ground,
so no one can tumble from a great height.
We marked each pumpkin with its weight.
