Nothing Artificial

According to Mary, nothing artificial is really artificial, because whatever it's made of is natural, even if you have to go a long, long way back to find the natural thing it's made of. After we told Scott about her observation, he told her about some PBS science shows he watched recently, and they got into an interesting discussion about how you get extra neutrons into atoms, how helium gets out of balloons, and how scientists discover smaller and smaller bits of matter. So, I'm off to visit the Real Science 4 Kids site to check out their Chemistry curriculum.
