I have three young kids ages 7, 5, and 3 at the time of this writing. They are home schooled, so we are in the habit of educating them in everything we do - especially the older two.
Taboos aside, there is a ton a kid can learn from home brewing, particularly STEM-related. Are there any particular activities you guys have done with your kids to help them learn about microbial growth, the scientific process, and all the other wonderful geeky things we enjoy while brewing at home?
update One thing we ended up doing was watching whatever we could find on YouTube about fermentation, culturing, etc. that I felt they could understand. What really hit the spot was watching a time lapse of a culture growing in a petri dish while I explained the process in 6 year old terms. We then built this using bottles, baker's yeast, balloons and electric tape:
The kids had a lot of fun with this and since it's baker's yeast it took less than an hour to blow up the balloons!
