This will help with Chemistry and if you get done, Earth Science

1)  http://www.classzone.com/books/earth_science/terc/navigation/visualization.cfm

2)  Scroll down to Chpt 5 and click on:

 How Many Protons, Neutrons, and Electrons Are in Common Elements?

3)  Step 1:  Record an answer for the six pictures, then click on Step 2.  Use your PT.

4)  Step 2: Tell me how big a Cu (copper) atom is. 

5)      Write down what you know about subatomic particles (p,n,e) with regards to charge, location, and mass.  Then, click Step 3 and move your cursor over the particles to check your answer.  How did you do?

6)      Try to build the first ten atoms of the PT and isotopes for each.  Follow the directions in the box.  Do you see a pattern?

a.       What happens when electrons and protons are moved near each other?

b.      What happens to the nucleus when it contains neutrons only?  Protons only?

c.       What happens when you try to put a third electron in the first energy level?

I am having difficulty uploading the file that fits with this.  You can see me in class or write me in this blog if you think you will need the corresponding worksheets and questions. 

Time to review and learn Plate Boundaries and Volcanoes inside out.

Volcanoes: http://dsc.discovery.com/convergence/pompeii/interactive/interactive.html

Plate Boundaries:

this one will help w/ plate boundaries as well

You received your rubric today.  This should be fun.  Please do not choose something you are not interested in.  Any topic can fit the criteria… GUARANTEED!

What will you do today to celebrate the Earth?

You can do anything you want and show me what you did for credit.  Examples include:

   – Awareness through Banners, Posters, Songs, Raps, T-Shirts, Poems

   -Reducing pollution by cleaning litter, cleaning a water source, recycling, educating others, reducing water use, or energy use, etc.

  – Come up with your own ideas.  Let’s see how creative you can be. 

Remember, we will be finishing Chemistry on Wed. April 15 and we will begin Earth Science the next day.

The final quiz will include everything we have done since December (minus the whining).

Here are some balancing problems:

1.  H2 +  O2 --->  H2O            26.  N2   +   H2  --->   NH3

2.  S8 +  O2 --->  SO3            27.  N2   +   O2  --->   N2O

3.  HgO --->  Hg +  O2            28.  CO2   +   H2O  --->   C6H12O6   +   O2

4.  Zn +  HCl --->  ZnCl2 +  H2   29.  SiCl4   +   H2O  --->   H4SiO4   +   HCl

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.

http://www.chemcollective.org/assignments.php#solubility

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

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:
