• 7. Does increasing the weight of the film can
  affect the buoyant force?
• Hypothesis When you add pennies to the can, the
  buoyant force will ________ because _________.
• Test it out
• Weight of heavier film can in air _____ N
• Weight of heavier film can under water _____N
• Buoyant force (subtract!!!) _____N
• Compare the buoyant forces (todays vs
  yesterdays)
• 8. How does the buoyant force compare to the
  weight of the displaced water?
• Collect displaced water from displacement tank
• Weigh it on the scale using NEWTONS!!!

Whats Inside an Atom?

• BLUE NEUTRONS
• RED PROTONS
• YELLOW ELECTRONS

A) below symbol atomic number Atomic
of protons(reds) B. above the symbol mass
number Mass number particles inside the nucleus
(reds and blues) C. Sometimes there is more than
one mass number- Atoms can have different numbers
of neutrons (blues) These are called isotopes. D)
What about yellows? Yellow electrons
Electrons equal protons Yellow Red

Rutherford Model Hit the Penny Model
Alpha particle (2 protons, 2 N)
Nucleus of gold atoms
Empty space of gold atom
Electrons
PROBLEM What is the Structure of the Inside of
an atom? Watch video segment- write 3
notes HYPOTHESIS Rutherford expected the
positively charged alpha particles to pass
through the gold atom
What does the Hit the Penny model mean? Why did
so few alpha particles hit the nucleus? Why did
they bounce off? (2 reasons) Why did so many
alpha particles miss the nucleus? Because the
atom is mostly.

Periods and Energy Levels

• Water / H2O.
• Is a COMPOUND Pure substance made of more than 1
  type of atom
• Is a MOLECULE Group of atoms bonded together
• Has 2 CHEMICAL BONDs holds atoms together
• Has a COVALENT BOND Electrons are shared.

• Each horizontal row is called a period.
• Periods tell us where electrons go.
• Elements in the 1st row have 1 energy level.
• Elements in the 2nd row have 2 energy levels.
• Etc
• Each vertical column is a group or family.
• What do they have in common?
