Rockets Project Information and Directions:

Rockets Project Information and Directions:

Save your notes from the WebQuest. You will need them for the final project report.

Everyone needs their own project packet. Make sure you read it all.
  • Put your name on it!
  • Read the whole thing.
  • You will be filling in the notes, questions, calculations and more as you build the rocket. 
  • Bring the packet to class every day. 
  • Everyone will have to write up their own project report (in their own words) and turn in the packet. 
  • Reports will be due by the Final Exam.
  • Do not wait until the last minute to start the report. You can work on it as you go through the project and then just finalize it after the launch. 

Rocket kits go into box top with paper with all team members' names.
All equipment gets returned to the front of the room (glue, tape, rulers, etc).
  • Make sure tops are tightly closed on glue.
  • X-Acto knives get signed out and returned to me. 

Read all of the instructions carefully before starting any building of the rocket.

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

Thermodynamics Virtual Labs and Investigations

Thermodynamics Virtual Labs and Investigations 

All students must turn in their own paper.

Lab 1:

–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:

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


b) Second change

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:
–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.

Google Science Fair - enter and win big prizes

The second annual Google Science Fair is open. Google started the science fair last year and it was a huge success. Students enter their projects and can win some really great prizes. The projects from last year were pretty impressive too.

Students simply register online, get parental consent, do their project site online and then submit the project.

The site has great tips and resources for students and educators. There are three age categories 13-14, 15-16 and 17-18 and prizes in each category. The one grand prize includes a trip to the Galapagos, a $50,000 scholarship, and a hands on experience at either Lego, CERN or Google. Other prizes include $25,000 scholarships, Chromebooks and Chromebook kits for their classroom, intern experiences and much more.

This is a great way for students to work through a science project and have it viewed internationally and have the chance to win some great prizes.

For more information or to get started, go to the Google Science Fair site. 

Doodle 4 Google Contest - win a scholarship

Doodle 4 Google

Google is once again hosting a Doodle 4 Google contest for K-12 students in the US. Students create a doodle of the Google logo based on this years topic "If I could travel in time, I'd visit...". The winner gets their design on the Google homepage and gets a $30,000 college scholarship along with a $50,000 technology grant for their school.

The theme, "If I could travel in time, I'd visit..." could mean visiting past, present, or future setting. Last year's contest had over 100,000 entries, so competition is fierce. There will be one winner per state and then from those 50 State winners, the 5 National Finalists and the National winner will be chosen.

This year the winning Doodle will also appear on a special edition Crayola 64 crayon box!!

To enter, you just need to submit your artwork by March 20th with a signed and completed entry form. 

There will be some celebrity judges along with the Google employee judges. They will determine the State finalists. On May 2nd, the State finalists will be up for public vote.

Being a finalist is pretty cool and all 50 state finalists will get flown to New York city for the national awards ceremony on May 17th. The winning Doodle will appear on May 18th and all of the 50 state winning doodles will be displayed at the New York Public Library.

Complete rules, prizes, and registration information is available at the Doodle 4 Google site.
