These are the first notes we've taken as a class, I have them here for an example of how we are taking notes. Please note that the green is Main Ideas, the blue is for Subtitles and the the red is for Evidence, Elaboration, Examples and Explanations... (notes). Also please note that each written entry is below the last written entry, this is to visually organize the information.

Elements Compounds and Reactions
* Element An element is the simplest form of matter
Atoms Compounds and Molecules
Atoms
* A single atom is the smallest part of an element that is still that element
* Each element has a different kind of atom
Compounds
* Sometimes elements are found as elements
* A compound is a substance that contains 2 or more elements that are chemically joined (ex. water)
Molecules
* A molecule is a group of 2 or more atoms joined together chemically
* A mixture contains different elements and compounds
* air is an example of a mixture containing nitrogen, oxygen, water vapor… which are NOT chemically joined
Chemical
Reactions
* Everything in the universe is made of different compounds composed of only 92 different elements
* These different compounds are made through Chemical reactions
* A chemical reaction is a process that rearranges atoms of one or more substances into one or more new substances
A Simple
Chemical
Reaction
* Chemical reactions start with reactants that are combined to make products
* Chemical reactions also produce energy, often in the form of heat.
