Taking care of business
Thursday you will need color pencils for class

Mindset Monday/Tuesday
Soichior Honda The billion-dollar business known as Honda began with a series of failures and fortunate turns of luck. Honda was turned down by Toyota Motor Corporation for a job after interviewing for a job as an engineer, leaving him jobless for quite some time. He started making scooters of his own at home, and spurred on by his neighbors, finally started his own business. Powerful Inspirational true story...Never give up!

Mass – Atomic # = Neutrons
MAN Mass – Atomic # = Neutrons

To find the number of neutrons: Subtract the atomic number from the atomic mass.

Remember, electrons are so small they don’t add much to atomic mass

ENGAGE: Is it an Atom, Molecule, or Compound
ENGAGE: Is it an Atom, Molecule, or Compound? From the list below, write “A” if you think the model is an atom, “M” if you think the substance is a molecule, or “C,” if you think it is a compound. If you think a substance is more than one of these, put more than one letter in the blank. Write your initial ideas on the left-hand side of the line. Record your responses after the lesson on the right-hand side of the blank.

Before the lesson: Explain why you categorized each one the way you did:
________________________________________________

After the lesson: Write a definition of an atom, compound, and a molecule using your own words.

EXPLORE: Molecule Card Sort
Sort the molecular cards into pairs which match the picture of the molecule with the correct chemical formula. Look for patterns in the cards to determine how chemical formulas are written and how atoms are color coded. Hint: Carbon = Black, Oxygen = Red

EXPLAIN: Construct an Explanation
How are chemical formulas written? What is the color-coded key for each element? Explain your reasoning:

Watch the Bill Nye: Atom video and answer the following.
atoms

Atoms come from a Greek work meaning _________________________.
Bill Nye uses a model known as an analogy to explain the concept of an atom. What does he cut in half, then in half again, over and over, until he eventually gets to the “unbreak-apart-able piece?” _____________ Atoms come from a Greek work meaning _________________________. Can atoms be seen by a regular microscope? ________ Atoms would not look like the model because they are mostly ___________. In the nucleus, there are two kinds of particles: ___________ and ____________. __________ are like letters and _____________ are like words in the universal alphabet of matter. The number of ____________ in the nucleus makes one atom different from another. The master list of all of the atoms in the universe is called the ________________________. When you put atoms together you get ____________________. H2O = _____________ NaCl= _________ C6H12O6 = __________ Everything in the universe is either _____________ or ________________.
