This powerpoint goes along well with my notes page on the Chemistry of Life. 12 slides cover atoms->elements->molecules->compounds. Also, we discuss each of the 6 main elements that makes up living organisms.
The aim of this lesson is to help bridge the gap from 8th grade science into biology by reviewing what matter is and how a living thing is made up of matter. However, it could be great for an anatomy class before going into biomolecules.
