Test Your Knowledge of Science With This Quiz

I missed two: water boiling at 212 is so ingrained that I didn't know there was any other answer. And I don't recall ever learning about how lenses work. But years of sound editing by computer helped with the volume question! Those are the three most people missed.

Got the magnifying glass one wrong. I think if the correct answer extended the lines a little further, I would have remembered it correctly.

Some of the questions aren't really even science. History of science can sometimes serve a pedagogical purpose, the end goal of science education is rarely to make you memorize people's names. Other questions, like defining a light-year, is by far not the most useful or relevant science topic as far as helping people.

How to read a graph on the other hand, is quite useful and important. I've seen some very well taught low level science courses that aren't really trying to get students to memorize facts, even if they are discussed, but instead trying to teach how to read science material and visuals.
