Chemicals are not like fine wines. They do not grow better as they age. Why?

- They can decompose when shelf life has been reached, they cannot react the same way because they expire. - Ethers can break down to explosive components as they get older. Just turning the cap can cause an explosive. - Picric acid, which once was used to preserve specimens but should never be in a school, because an unstable explosive when dried out. - Many powdered reagents become so hard that they cannot be removed from their stock bottles.

General discussions, keep hands washed

For K-12 and science education communities, nature of science is not so much defined by a concise statement, but rather defined more by its components:

That science is a way of knowing, and there are values and beliefs inherent to the development of scientific knowledge (Lederman 1998); • That the philosophy, history, sociology, and psychology of science affect science teaching and learning (McComas, Clough, and Almazroa 1998); • That science is a human endeavor and that people of all ages, races, sexes, and nationalities engage in this enterprise (Weinburgh 2003); and • That science is based upon evidence—not logic or faith (Weinburgh 2003).
