“Fear of Numbers” By Cynthia Macdonald My prediction for this article was that kids are sometimes really scared of numbers and that’s why they don’t do well in math. The article never really said that but for me I think the author put “Fear of Numbers” as the title since some people don’t understand math and they don’t want to be looked down on in society‚ since it’s embarrassing if you don’t know if you have enough money for a coffee. But if I was the one who wrote this I’d call it “Suiting the

How was Avogadro’s number determined? Jessica Kim 12D Starting from 200 years ago‚ scientists tried to figure out the basic ideas of chemistry. One of them they put lots of effort in was to find out the mass of the smallest particle‚ mole. Measuring the mass was a primary difficulty at that time since one mole of a substance was unable to weigh without using developed technology. Even though‚ it was clear that everything was made out of a small unit‚ there was no evidence that could determine

Number One By: Jill Nelson I like this story by Jill Nelson. Jill Nelson and her family were living well for a black family back in the 1960s. Jill’s father would have the family sit at the table for Sunday breakfast and preach his own version of the sermon.
