Appearances don’t always show what is on the inside. If you get a strict teacher, is she just being mean or is there something more? Graphene is a material that is super thin but is it weak? Don’t assume facts about something just from their look.
“Miss Awful” by Arthur Cavanaugh shows a substitute teacher for a 3rd-grade class. Their original teacher is very flexible and lets the students do whatever they want, but the sub, known as Ms. Orville or Ms. Awful, was very strict to them. The students hated her as they were forced to behave a certain way but we later learn that she just wanted to teach them to be less violent because of something she has been through. Having Ms. Orville not only taught them to behave but also helped them learn more academically.
Graphene is a material that was discovered a few decades ago, and it is a 2D, one-atom thick version of graphite. If it’s so thin, people may assume that it is very fragile but it’s actually many times stronger than steel. People also may assume that this material would be used in everyday materials, but because of difficulties doing things, such as mass-producing, graphene hasn’t been used as much.
Whether it’s an extremely thin material or a teacher who’s very stern, you shouldn’t judge them on what they look like or how they act with limited knowledge. Don’t judge a book by its cover.
