This was Quin's project about second hand smoke. The plant on the right has no new growth and the leaves are much darker. It was the one exposed to just one cigarette a day! Ick! (It still stinks terribly!)
This was Levi's project about water and sewage filters. A little harder to see his results but he put alot of thought into it and when the judge asked him to explain Mom had to leave... My son is definitely the verbose one! LOL!
And these were some that were particularly creative and visual!
After spending all day in town with mundane tasks like grocery shopping, it was refreshing to see my kids stretching their brains and thinking outside the box! Kinda re-energizes me! :)
