Hello all, my daughter is in 7th grade & has her science project coming up. She's a very bright & intelligent girl so we're looking for something a bit more interesting than "Do plants grow better with Brawndo or Water?". Last year, she did her project on audio sample rates and if people could hear the difference between samples of 44.1Khz vs 98.6Khz (yes, it's true - CD quality is as good as your ears can ever hear!) so she's capable of handling actual science.
Both my daughters & I are musicians, so her project actually meant something to her.
In keeping with that theme, we just moved into our house a month ago and we finally have a pool! So, she said she'd be interested in something to do with chemistry & since testing the pool & keeping it running well is all about chemistry, it would be relevant to her.
With that in mind, can anyone think of any pool related science that would be fun to not only do, but useful for anyone with a pool? We have to avoid things like "Which pool shock tastes better?" or anything simplistic like product comparison, but at the same time we don't have a chem-lab to perform quantum-state predictions on the free chlorine.
I mean, we have a 22k gallon bucket of 'ready to chemically abuse' fluid right outside so any thoughts or ideas would be fantastic.
Thanks a Ton,
