Assignment for Friday, March 30, 2012

I'm still out sick with bronchitis. Here is  your assignment for today, Friday. Have a good weekend.

No more than 3 people in a group.
One paper per group.

Geometric Optics Lab

1. Go to  and run the simulation.
 Take the pencil and raise it so that the eraser is sitting on the principal axis. Click on the “principal rays” button.

1.1 Draw the ray diagram. Describe the three special principal rays: how do they enter the lens, and how do they exit the lens?
1.2 There are several properties of the lens you can change in this simulation. For each one below, PREDICT what you think the effect will be on the image (its size, location, and brightness), then give the actual answer:
a) Radius of curvature of the lens
b) Refractive index
c) Diameter
1.3 You can change the location of your object (the pencil). Drag the pencil so that it is farther away from the lens. Explain the result.
1.4 Drag the pencil so the eraser is right on top of the focus. Draw the ray diagram. A) What happens to the two principal rays that enter the lens? B) Will they ever form an image?

Turn in your answers and observations at the end of the period, even if you are not done.

Attention - Important notice about AP Exams and FEES !!

Dear AP Students,

Monday, 3/12/2012, the school received word that the Federal government has slashed its funding to states for AP exam fees and the State of Connecticut is not providing any increase in their funding either. 

Because of these cuts, you will have to share the costs of the exams. Again, you will have to pay for part of the exams this year. 

The costs are as follows:
  • $15 per exam for the first three exams
  • $53 per exam for the 4th, 5th, 6th or additional exams.
So, if you are taking 2 AP exams, it will cost you $30. If you are taking 4 AP exams, it will cost you $98
( 3 x $15, and then $53 for the 4th exam).

A letter will be sent to your parents about this change in AP testing and fees. 

If any additional funding becomes available from the Federal or State governments, refunds could be given, but there is no definite notice of that happening. 

We know this may be a hardship for some students. This is not a Bridgeport thing, it is due to Federal and State cuts. 

More information will be coming soon. 

Mr. A

High School Grades 9-12 Contest Challeng

Reducing Your High School’s Carbon Footprint

Write a letter to your principal about what you and your fellow high school students can do to address the problem of climate change in your high school. What actions can you take to reduce the school’s carbon
footprint? Be sure to include a comprehensive carbon footprint reduction plan, including the installation of energy efficient technologies (example: lighting, boilers, air conditioning), renewable energy sources, recycling, transportation and energy conservation behaviors (example: turning off unnecessary lights). Please submit a four to six page letter addressing the actions you would suggest, any issues or concerns regarding those actions, and any anticipated outcomes. You can include graphs, diagrams and
references only if they support your plan.
