  Key for BCRs we did in class Wednesday.  
     
     
  Week 20: June 6-10th, 2011 (added 6-4-11 at 5:52 pm)  
  This is our last week of classes.  On Friday period 1 & 2 will take their final exam.  Period 3 & 4 have theirs Monday.  

Check Edline now to see if there are any problems.

The exam is not an easy one.  It requires preparation.

The key for the practice work we've been doing is available in the Class Notes section.

Remember to bring your books before or on the day of the exam.

All the best,

Dr. B.

 
     
     
  Week 19: May 30th - June 2, 2011 (added 5-27-11 at 2:38 pm)  
  With seniors gone we'll begin preparing for the final exam.

This week well prepare for the final exam.  For many students this will determine the grade that will go on your transcripts.  For example, if you have a B for both quarters youll need a D on the final.  Otherwise youll have a C on your transcript for this semester. Take a look at this page to see other grade combinations.   Even if youre not concerned about the final exam it can influence your grade as several assignments will be collected.  

The BCRs for the exam are online.  Ill choose two at random for each class.  You can see the BCRs right now and prepare.  It is highly recommended you spend some time studying and planning out how you will answer each BCRs question.  The BCRs are at the end of the document.

The review packet we'll be working on in class is available in the Class Notes section.

We'll discuss study strategies in class.

Youll want to also be looking at Edline to see if you are missing any work.  No work will be accepted after Friday.

Dr. B

This week well prepare for the final exam.  For many students this will determine the grade that will go on your transcripts.  For example, if you have a B for both quarters youll need a D on the final.  Otherwise youll have a C on your transcript for this semester. Take a look at this page to see other grade combinations.   Even if youre not concerned about the final exam it can influence your grade as several assignments will be collected.  

The BCRs for the exam are online.  Ill choose two at random for each class.  You can see the BCRs right now and prepare.  It is highly recommended you spend some time studying and planning out how you will answer each BCRs question.  The BCRs are at the end of the document.

The review packet we'll be working on in class is available in the Class Notes section.

We'll discuss study strategies in class.

Important Note:  Thinking about what is happening at the molecular level (which we cant see with our eyes) helps us explain what is happing at the macroscopic (what we can see with our eyes) level.  Strong theories allow us to explain and predict.

Always use Kinetic Molecular Theory to think about what is happening at the molecular level.  KMT is the basis for much of how we understand the behavior of gases.

  The plan for this week is in the post below this one.  

If you're missing a lab assignment you can complete this as a substitute (Due Wednesday, December 2nd for inclusion in the upcoming interims.  Otherwise due Monday, December 7th.)  

In your own words (please cite any sources, being careful not to plagiarize others work) describe how scientists know there is water on the moon.  

Use the following words in your writing: spectra, light, spectrophotometer, near infrared, and wavelength.

Youll want to look at the mission update on the NASA web site for specific information.

In your paper you should discuss (okay to copy into your paper if you cite the source) the graph at http://www.nasa.gov/images/content/402252main_LCROSS_results10_full.jpg.

You may also speculate on the importance of this discovery for society.

The paper should be 300 words in length and will be checked via the web for inappropriate use of others' work.  
 
     
     
  Week Fourteen: November  30 to December 4th,  2009 (added 11-26-09 at 11:21 am)  
  This week interims will be completed on Wednesday, December 3rd.  If you are missing anything you'll need to figure it out before then.  See EDLINE for any missing work.

We'll continue with stoichiometry this week and have our UNIT TEST on Friday.  After that things get a bit easier.  But we'll need to push to get through this week and do well on the unit test.

People keep asking me where to get an AirZooka.

A few thoughts:

Make sure you get the basics (GFM, moles to grams, what the coefficients mean in a chem. Equation).

Use a problem solving strategy (identify what is given, what you need to find, what conversion you need to make, does your answer make sense?).

Use worked problems in class as a learning tool.

Lab Safety Tips

Always wear your goggles when cleaning up.  This is when many accidents occur.  

Keep your goggles on until instructed to remove them.  Others still working could splash or spill dangerous chemicals.

Be sure to wash your hands after a lab.

Never eat or drink in the lab.

Important Note:  Thinking about what is happening at the molecular level (which we cant see with our eyes) helps us explain what is happing at the macroscopic (what we can see with our eyes) level.  Strong theories allow us to explain and predict.

Always use Kinetic Molecular Theory to think about what is happening at the molecular level.  KMT is the basis for much of how we understand the behavior of gases.

  Week Nineteen, January 8-12th, 2007 (added 1-7-07 at 11:23 am)  
  This is our last week of the semester.  Time to get ready for the final exam.

But first, a Periodicity Quiz this Monday.

For the final, take a look at the class notes and presentation to see what you need to know.    Remember, you can go back and view all class notes, links, presentations, and practice tests in the Class Notes section of this site.

You may also want to look at the review sheet from the county to see what’s on the exam.  

Last week I wrote about a video from a show called Brainiac.  It turns out that some of the explosions were faked.  Making up data in science gets a lot of people mad and hurts your credibility.  Take a look at actual explosions – still pretty impressive.
