Unit 8.2 Gathering Evidence
Students learn the relationship between atomic structure and light energy in atoms of metals and they learn how to apply their knowledge to solve a real-world problem.
Video program cues: 5:05-16:00

Chemistry is central to life

"If I were in charge around here, I would basically say that chemistry should be a compulsory subject for every student in the U.S., whenever they can take it, whether it be ninth grade, tenth, eleventh, or twelfth grade. It's not because I’m saying we need lots more chemists, or everybody should be a chemist, it’s because chemistry is a basic subject, and so many of the things that happen around us in life happen because of chemistry. Good things and bad things. And there are many societal issues facing us today that do involve an understanding of chemistry, in order to be solved. And they will be solved, not just by chemists working with solutions, but also by a whole array of people working on solutions."

Chemistry is everywhere

"I think it is very underestimated today how dependent we are and how friendly chemistry is: from the clothes we wear to the food we eat, to the furniture we sit on, to the cars we drive, chemistry is a central science, it is critical to all of these things. We just take it for granted. And at the same time, it is very unfortunate that the word chemical, in these modern times, has a negative connotation. I can guarantee you that we would all be dying from Bubonic Plague and all sorts of other things, which are terminal, if we threw all the chemistry that we know out, and go back to the old style. It's a wonderful science, it's got great applications, and it isn’t as hard as people say it is."
