All Room 506 students

Congratulations, your generosity allowed us to donate more than $200 of the schoolwide total of $1300 to families suffering from Lymphoma and Leukemia.

I knew there was a reason I liked [some of] you folks.

Honors Schedule

I guess its just one darn thing after another. Here is our latest darn thing. [Actually this subject is kind of cool if you try to understand it rather than just answer examples].

Labs

1) Labs continue to come in with vague purposes such as "to explore the ...." or " to confirm the relationships among...... [without telling what those relationships are expected to be]". The explore one is actually okay for the wave properties lab although "c/f =lambda , c is a function of medium only, amplitude and frequency are independent, etc. " would have been better.

2) There is still far too much copying of nonsense from one report to another. One member does something silly and 3 other members dutifully incorporate the error into their report.

3) When I provide you with a packet from a manual do not give me the whole lab packet. I have already read it. Just give me the lab reports with your own original purpose and results.
DO FILL OUT the lab results heading with date, lab partners, as well as your own precious names.

Grades

I've just posted your grades to the High Anxiety Causer. They were not what makes a teacher's heart glow ( assuming he/she had one). Low lab grades mean you have received the dreaded "see me" on one or more labs or have more efficiently just decided not to turn a lab or two or three in.

Again, The only numbers that have any meaning are the individual categories. I don not use eschool's method of calculating overall grades, and be thankful.

Honors

I hope you are reading this before Sunday night.

1) You should be choosing among the six systems for the fusion power plant. Choose three in order of preference from
Plasma
Plasma heating (Neutral beams, ohmic and RF)
Magnets ( Toroidal, Poloidal, OH)
First Wall and Blanket
Thermodynamics ( Steam cycle)
Electric Generator

2) You should be able to have done all the homework for our current Unit (9) sop turn it in Monday

3) Be prepared for a short quiz Monday based on the homework

Juniors who think they will go to college

If you have good grades and standardized test scores and have family incomes of about $60,000 or below, take a look at this site:

Pennies for patients

We collected about $10 today. Not bad, but let's be even more generous to people who have serious troubles.

We are currently in third place. Let's show the school that we are made of the right stuff.

I have no idea how the link ended up with the wrong Revision

here is the correct one. I'll accept the homework on Tuesday

Speed of Sound ( Resonance) Lab

Lab is informal

1)Write a purpose that discusses the relationship between air column length and wave length for resonances ( standing sound waves) and about how we find c using wavelength and frequency. and brief conclusion stating what we did prove or disprove.

2) Answer all questions except the ones about end effect E.

3) Make sure you answer the question about change of temperature's effect quantitatively e.g. my measured lengths would decrease by 2 % -don't quote me this is not the right answer.

4) Also say what frequencies can give resonances for a tube. i.e. Are they a particular number times the original frequency?

5) Open tube means open at both ends.

Honors Schedule for Fusion

Here is your schedule. Please note that you must choose a part of the fusion power plant for your project by 2/28. IN FACT choose the first three favorites and list in order of preference.
