Atomic Theory Polka

• Dalton, Thomson, Rutherford and Bohr.
  Schrödinger and Heisenberg, and many, many more.
  Used their brains to venture in the realm of
  inner space and found the world of the atom was a
  weird and wondrous place.

25

• Dalton did experiments and said, I think its
  clear, atoms are tiny indestructible spheres.

26

• Thomson worked with cathode rays and said, I
  disagree. A plum-pudding model makes much more
  sense to me.

27

• A new chapter in atomic theory started to unfold
  when Rutherford played around with atoms made of
  gold. When a few of his alpha particles came
  bounding back, he hypothesized a nucleus had
  knocked them off the track.

28

• Dalton, Thomson, Rutherford and Bohr.
  Schrödinger and Heisenberg, and many, many more.
  Used their brains to venture in the realm of
  inner space and found the world of the atom was a
  weird and wondrous place.

29

• Bohr saw spectral lines for hydrogen and said,
  It seems to me.. Electrons move in orbits with
  specific energies.

30

• Heisenberg said, Forget it, theres no way to
  know the orbit or a path, where the electrons
  gonna go.

31

• Schrödinger used lots and lots of fancy
  mathematics, and made a model of the atom based
  on quantum mechanics. It has orbitals and those
  are based on probability. The atom is a fuzzy
  blob of pure uncertainty.

32

• Dalton, Thomson, Rutherford and Bohr.
  Schroedinger and Heisenburg, and many, many more.
  Used their brains to venture in the realm of
  inner space and found the world of the atom was a
  weird and wondrous place.

Atomic Theory Pictures

• Cut out atomic pictures and put into notebook
  next to appropriate scientist.

Cation Lab

• In two days we will begin our next lab.
• Read through the lab to familiarize self with
  procedures and research techniques you are not
  familiar with.
• Begin writing introduction.
• Set up your data table.

36
Intro

• What is the goal of the lab?
• What data will you take to achieve that goal?
• How will you use that data?
• Who in the real world does this?
• What do they look at? 
• How is this similar to our lab?
