Do Now: 
1. Record the following in your Do Now notebook: 
"12/5: Why were the salt, food coloring and water the hardest parts of the SLUDGE to separate?"
2. Pick up a Physical and Chemical Properties notes page from the front counter. 

Today's Goals:       [Review the "Cookie Crumbles" packet to see what you already know]
What characteristics can we use to describe different types of matter?
(Let's begin our studies of Physical and Chemical Properties and Changes.)

Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.(MS-PS1-1) Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. (MS-PS1-3) Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. (MS-PS1-3)
