ANNOUNCEMENTS:
• Science fair notebooks due Friday.
• There is another mentor letter on line on www.mrjamsa.com
• You must read it TOGETHER and then communicate to me you have (with questions) by FRIDAY.

NEW WORD FOR YOUR DICTIONARIES:
• Atoms: The smallest particle of an element that still has the properties of that element. They are the tiny “Legos” that make up all MATTER in the universe.

ALL MATTER IS MADE OF ATOMS

OLD MODEL OF ATOM
• Everything spread out – mostly space.
• Electrons evenly spread throughout.
• Mostly space

TYPICAL TEXTBOOK VERSION OF ATOM
• Nucleus:
• A) Protons – positive charge (big)
• B) Neutrons – neutral charge (big)
• Flying around the outside –
• A) Electrons – negative charge (tiny)
• 2 in the first shell
• 8 in each shell thereafter – sort of
• MOSTLY EMPTY SPACE

ALL MATTER IN THE UNIVERSE IS MADE FROM THREE PARTICLES!
• Sentence with three letters of the alphabet?
• MY NAME IS BILL.
• I, O, B

ELECTRON CLOUD MODEL
• Electrons flying around fast – all we can do is visualize where they probably are.
• Atoms act AS IF the electrons are everywhere.
• But if you look, they jump to one place.

COOL FACTS ABOUT ATOMS
• 1) All of the matter in the human race can fit in a sugar cube.
• 2) Electrons move from one level to another; they don’t jump – they disappear and reappear.
• 3) E=MC2 – Ultimately energy and matter are the same!
• 4) There are 100 trillion atoms in a typical human cell (100,000 billion)

EXTRA CREDIT OPTION
• An A for every student in the class if you write for me on paper 1 billion Xs.
• Let’s do the math…
• How many Xs in one hour?
• One day?
• One week?
• One year?

WATCH THE FILM
•Write down interesting facts and comparisons about the atom.
• The rabbit hole just keeps getting deeper…
• You will need them for your Acrostic at the end.
