The next-to-last class this session consisted of 2 experiments:

Modelling a volcano:

Paper cups painted dark green, topped with small plastic cups in which baking soda & vinegar were mixed to bubble up & spill over again & again, until we ran out of vinegar. I drew a volcano belching smoke on the whiteboard to show context. A little (Chinese) boy named it “Storm”.

Making small magnets slowly repel each other
along a pencilled S-route.

Grinning Maggie (Chinese/German) instantly figgured out that a ‘better’ route would be a straight-line, or even no line at all! Finally, the little (Chinese) boy drew a cartoon face & used the small magnets as its googly-eyes, proudly showing it to his mother when she came to pick him up. She told me he had already made a volcano at home. Now he has 2.
