Student Contest on Energy - cool prizes - see me to enter

eesmarts 2012 Student Contest

The Connecticut Energy Efficiency Fund has announced its eighth annual eesmarts energy efficiency student contest inviting students to enhance their skills in science, writing and technology. Students are asked to answer grade level-specific prompts regarding efficient and renewable energy technologies in a variety of formats including a poem, a news article, an essay and a television commercial.

The contest is open to all Grade K-12 students in Connecticut and all essay prompts align with the Connecticut State Frameworks in science, mathematics and writing.

All participants receive recognition for their submissions and winners will be honored at a special awards ceremony on May 22, 2012 at the State Capitol.

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.

Homework:  Chp 18 Problems: # 5, 7, 11, 13, 27, 33, 43
Due Thursday, 3/1

We will go over the homework and then do Chp 19, DC Currents on Thursday.

We will be doing labs after Chapter 19.

There will be a quiz on Chapters 16-19 also (sometime next week)

Electric Potential

Today, Monday, February 27th, we did "Electric Potential" which is Chapter 17 in your book.

Lecture notes are here:
https://sites.google.com/site/dandradeedusite/Home/ap-physics-class-files
"AP Physics - Chp 17 - Electric Potential.pdf"
Homework is Chapter 17, Problems 3, 5, 15, 21, 35, 37, 43, 47

Tomorrow, Tuesday, February 28th, we will go over the homework and then do the Chapter 18 lecture "Electric Current"

(so start reading Chapter 18)

We will be doing labs after chapter 19.

Electric Charge and Electric Field

Today we finished Chapter 16, Electric Charge and Electric Field.. Homework is Chp 16 Problems: # 5, 7, 9, 23, 25, 27, 31.
We started the first lab today too.

On Friday we will go over the homework and then continue the lab.

Over break, don't forget to do the practice test problems. After break, we will go over them and then finish the labs for this chapter and then continue onto chapter 17. It wouldn't be a bad idea to read chapter 17 over the break either.

See you Friday!


Great job today too!

Thermodynamics Virtual Labs and Investigations

Thermodynamics Virtual Labs and Investigations 

All students must turn in their own paper.


Lab 1:

•http://www.7stones.com/Homepage/Publisher/Thermo1.html
–Change volume, E, and molecules and observe what happens
Write observations, calculations, answers to questions down. What did you see? Was this what you expected? How do the laws of thermodynamics apply? Etc. 



Lab 2:
•http://phet.colorado.edu/simulations/sims.php?sim=Reversible_Reactions
–
Run simulation, change variables and observe what happens.  Write observations, calculations, answers to questions down. What did you see? Was this what you expected? How do the laws of thermodynamics apply? Etc. 

Notice that you can adjust the height of each side of the reaction.

What do you think the ruler in the middle represents?

Move the middle bar to 50.

Move the reactant energy platform to 25. Keep the products on the lowest
possible setting.

Would you expect this reaction to be endo or exothermic? Why?

Add 50 particles to A.

Press start. Record what happens.

Attempt changes to the reaction conditions that will increase the amount of
product.(Record what you did and the results)
a) First change

Result.

b) Second change

Result.

Which change you made above would best simulate the addition of a catalyst to a
chemical reaction.

Now move the products to 25 and place the reactants at the lowest possible
setting. Start over with a new 50 particles. Record what happens. Would you
expect this to be more or less spontaneous? Why?



Lab 3:
http://jersey.uoregon.edu/vlab/Thermodynamics/
–Read directions and do all 7 experiments

Write observations, calculations, answers to questions down. What did you see? Was this what you expected? How do the laws of thermodynamics apply? Etc.
