This is a zipped file of 3 PowerPoints from the mind of my husband, a high school science teacher.
One is simply called "Chemistry". The subheadings for this one are:
The second is called "Properties of Matter". The subheadings are:
-Chemical and Physical Properties
-Chemical and Physical changes
The third is called "Atomic Structure". The subheadings are:
-What are Atoms?
-Atoms are the building block of molecules
-Protons, Neutrons and Electrons
Hope this saves you some time! :)
