Honors: Velocity Practice and Acceleration Intro

Bellwork followed by some notes:

Homework tonight are Ranking Tasks Velocity II and Acceleration II.

Conceptual: Kinds of Radioactive Decay

Bellwork:

Notes:

Homework tonight is to finish Concept Development 39-1.  Due tomorrow.

Honors: Velocity and Relativity

Homework: Ranking Tasks People on Trains and Velocity I

Conceptual: Isotopes

Bellwork and notes below. I also passed out Concept-Development 39-1 for homework, but it is not due tomorrow because we have not done the front. It will be due Thursday.

Honors: Position and Speed

And so begins our kinematics unit. Most students from previous years have told me that this is the most difficult unit because we use quite a lot of math. First, some bellwork:

And notes:



Homework is Kinematics I, due tomorrow.

Conceptual: Radiation Intro

Most years we do a lab with cloud chambers to see some nuclear radiation, but I don't have the funds this year. Instead, here's an awesome video of a giant cloud chamber in Berlin.

Finally, we went through and talked about some of the items on the Nuclear Technology Affects Us All checklist. Turn this in for some completion points.

Test: Quantum

Many of you have missed several days this week due to AIMS makeup testing. I will allow those students to take their test Monday after school. Everyone else, don't forget your note card and calculator today!

Study Guide: Quantum

Spectra Lab

Today we did the Spectra Lab.  If you were not here, I will simply excuse you for it.  If you want to make it up, you may do so after school.  Alone, it will probably take you 20-30 minutes.

Spectra

Conceptual bellwork:









Honors bellwork:






Notes Below. There is a nice page with the spectra of each element here. Homework is Quantum IV (Conceptual, Honors)

Photon Emission and Absorption

Bellwork:






Notes...which don't make a whole lot of sense if you weren't there...










Here are some websites that explain:
Regents Prep - Bohr Model
McGraw-Hill - Play with Absorption/Emission
University of Toronto - Another Animation of Bohr Model

Homework: Quantum III (conceptual) or Quantum III (honors). 

Discrete Energy Levels

Remember, the Bohr Model is not technically correct, but it helps us explain why only certain energy levels are allowed.

Here is a nice animation of the electron standing waves around the nucleus from the University of Toronto.

Homework: Quantum II.  Note that the wavelength of electrons for does change with the energy level - the speed changes, which affects the deBroglie wavelength.  But in #3 and #4 on the homework, we're going to simplify things a bit and assume the electron wavelength is the same for all energy levels.

Particles As Waves

No homework tonight.

Practice: Quantum I

I figured you all probably forgot a lot over the long weekend, so we spent today practicing what we already know. Tomorrow we will move on to new stuff.

Conceptual: Quantum I
Honors: Quantum I

These are due tomorrow.

Photoelectric Effect

Today, a very quick discussion of the photoelectric effect. Honors did this yesterday and receives a more in-depth reading on the photoelectric effect today. Homework for Conceptual is Energy of Photons and for Honors is Photoelectric Effect.

Quantum and Photon

No homework for Conceptual. Homework for Honors is Energy of Photons.

Marble Lab

Today we are finding the diameter of a marble without actually measuring the diameter directly! How is this similar to Rutherford's Gold Foil Experiment?

Marble Lab

Rutherford's Gold Foil Experiment

Today we talked more about Rutherford's gold foil experiment and derived the math for our own experiment for Monday.

The Atom

Today we went over some of the models from yesterday's reading. Homework tonight is Atoms.

History of Atom Model Development

Today we read a short (abridged) history of how our current model of the atom was developed. Your homework is to turn this into a timeline, due tomorrow.

Reading
Homework

Test!

This test covers reflection, refraction, mirrors, and lenses. Next unit: quantum physics!

Study Guide Day!

Today is your day to work on your study guide. It is unit 3 for conceptual and unit 2 for honors. Below you find pictures of the back of the study guide and the abridged answers. Test tomorrow!
