How to Make Bendy Bones

If you ask most kids what bones are made of, they would quickly answer "calcium!" Though it's not incorrect, years of us telling them to drink their milk for strong bones has hidden an amazing feature of nature, biomineralization by proteins.

Spatial Reasoning Puzzles with Magnetic Tile Circuits

This post gives some examples of puzzles you can set up using our magnetic-tile circuits to help develop spatial reasoning skills... and because they're just really fun. Spatial reasoning is the ability to mentally manipulate shapes or images by rotating, rearranging, regrouping, etc. Aptitude in this skill is linked to better performance in science, technology, engineering, [...]
