For grown-ups
BraidPals is a first look at one big idea in biology, before any molecule has a name: a thing's shape fits its job. First your child braids three strands of wool into a rope and feels how strong three together are.
Then six everyday things are matched to their jobs by shape: twine is a rope, a straw a tunnel, tongs a grabber, a toy train a stepper on its track, a cheese grater a cutter, a tray a carrier. The last line says that tiny shapes inside us do jobs like these too. We name no molecule under age nine; the same six jobs, done by six named proteins (collagen, aquaporin, an antibody, kinesin, trypsin, haemoglobin), are in TraitForge's Shapes that do jobs for ages 9–14.
The pictures are simple drawings, and the app says so. Each thing has one honest line, and nothing "wants" or "tries" anything: shapes work because of what they are, not because they choose.
