N

Yesterday we started the day at the doctor’s to have a spot removed on Neva’s face. The liquid nitrogen the doctor used made a huge impression on Simon. The doctor in turn was impressed that Simon knew that nitrogen is written as N in the periodic table (it has a very different name in Dutch). When we came home and wanted to look nitrogen’s qualities up it turned out that Simon also knows which number the elements occupies in the periodic table – number 7. We looked up nitrogen’s boiling temp: -196′ C. Today Simon was reading the encyclopedia again and made a little scientific discovery (Well, he did suggest it yesterday and found the confirmation today): “Mom! Nitrogen does boil at exactly the same temperature at which air freezes!”
