Review of Periodic Groups and Drawing Atoms Scavenger Hunt

1. You must list 1 adjective for each of the groups of representative elements.  Then, check http://www.shodor.org/unchem/basic/atom/ to check some of your answers and see if there is anything you can add. 

1. If Lithium reacts vigorously with water, name one other element that may also react strong with water and explain why you picked that element.

1. You will now attempt to learn electron dot diagrams (also known as Lewis Dot Structures).  Visit http://nobel.scas.bcit.ca/chem0010/unit3/3.3.2_Lewis.htm and
   1. Define valence electrons.
   2. Draw Bohr’s diagram for each of the elements in the first group displayed.  Is this how we drew them?  Explain what happens as you go down the periodic table in Group 1. 
   3. Compare and Contrast the elements in Groups 17 and 18 (7A and 8A) using the Bohr’s models.

1. If chlorine reacts strongly with sodium, would you expect the same from its next-door neighbor Argon?  Why or why not?

1. Define Lewis Electron Dot Symbols, then use that definition to write a dot diagram for K. 

1. Now click on the rules in gray for drawing Lewis Dot Structures.  After reviewing the rules, check your answer for K in question 5.  Then attempt to apply the rules to the following elements: Ca, Al, C, P, O, F, He, Ne, and Ar.  Do you see any patterns?  Check your answers below to see if you can draw these.  They weren’t that hard were they?

1. When you feel good about Dot Structures and Bohr’s Diagram, take a second to review isotopes (look left).  Pick an element and show me two isotopes similar to the example shown. 

1. Click at the bottom left on Problem sets 1, 2, and 3.  Complete the questions on your computer. 

1. If finished, use this website to review physical and chemical changes.  Try the problem set.

1. Tell the person next to you how happy you are that they are your partner.

XC:  What do you know about how an atomic bomb works?  Can you relate it back to our discussion of an atom?

When and why did WWII end (special focus on our involvement with Japan)?

Atomic Timelines will be due on Friday. 

Flame Test lab on Friday…Dress Appropriately

Use the following links to help you with your Atomic Timeline.

History of the Atom and Atomic Structure Models

You will review the History of the Atom by making an atomic model time line.  The following links may be helpful.  Be sure to include the following people, what they did, and when they did it.

1) Democritus             2) Heisenberg              3) Rutherford            4) Bohr       5) Thomson      &          6) Dalton.

We are finishing week 2 of the second marking period with a quiz on the macro properties of matter.

   It will involve review of physical/chemical properties and changes, the law of conservation of mass, and the newer concepts like solubility and separating a mixture.  Remember, we completed the sand/iron/ salt lab to separate a heterogeneous mixture and the distillation lab to separate a homogeneous mixture. 

Quiz Helper:  The final question on the quiz will be: 

Compare and Contrast the methods used to separate a homogeneous mixture and those used to separate a heterogeneous mixture?

Also, you will need to understand this diagram fully:   http://en.wikipedia.org/wiki/File:Simple_distillation_apparatus.svg

compliments of wikipedia.

Lastly, I have a virtual lab with extra credit problem from Chem Collective that you could try.

I am interested in you solving any of the problems at on Salts and Solubility for points towards the quiz.

3.  We will complete a Physical/Chemical Change Lab in Seminar (all week) and during regular class either Friday or Monday. 

4.  XC if you can tell me why Ammonium Chloride was a trick question in the lab we did today.  Was it a Physical or Chemical Change?  What is special about the heating of this substance?

Now that Chem is here, the notes are all posted on the Chem page to the right. 

You should complete your worksheet on Density and States of Matter by Th. 12/11.

We will probably need to dress for lab on Monday.  Remember, don’t wear your best clothes.

XC:  For the Final…Bring the packet of notes, tests/quizzes, vocab, classwork/hmwk, and calisthenics to the final with you on the week of 1/19.

In addition, bring the review sheet for the final and your Course Overview.  If you have highlighted and written specific questions, there will be more points for you.

XC Qof Day:  What was the name of the unidentified glassware in the picture during class?

As we wrap up the marking period, here are some items to keep in mind:

1) Test corrections in proper format for the unit test on Force are due on Wed. November 12.

2) I have attached a practice worksheet on Force and Distance graphs in order to calculate Work.  It will be counted as XC if it is completed.   wksht_work_shoe

3) Below is a copy of the homework assignment that was distributed in class today:

Science homework – Due:  Friday, November 7, 2008

Define the following words – on a piece of notebook paper and in YOUR OWN WORDS:  work, joule, energy, kinetic energy, potential energy, heat energy, gravitational potential energy, Law of Conservation of Energy, KE=1/2  x  m  x  v²,

PE=m x g x h, W=F x d

Write an original sentence for each word above (total of 11 sentences) OR use each word in a creative story.

Create your own world.  It can have any activity you would like.  It can be any medium your prefer: picture, video, powerpoint, story, blog, etc.

The only rule is that the world has NO FRICTION.  The more creative, the more points.

Major unit test for Science is Thursday 10/30.  It will involve all information on Force and Motion covered recently. 

We will begin our final section of Physics (Energy) next week. 

First unit quiz of MP2 on Friday 10/17.  Be there or be square.

Major project for MP2 will be due 10/24, with extra credit for those ready by the 22nd.  You should be able to work on the first and third law aspect of your project for homework. 

Notes are attached if you want to practice and study for the quiz. 

I have also attached a rubric for those of you who lost yours.  You must have one on the day your present.  raft_newtons-laws

Last but not least, XC question of the day:

After doing the experiment with the spring scales (pulling) and the bathroom scales (pushing), how would you word a law that explains what you saw?  (That rhymed)
