Unit 2 - Atomic Structure
This unit now really starts to take us into chemistry and the periodic table.
What do the numbers on the periodic table mean?
How do we use them?
What really is an element and what is it made of?
For Lesson 2.C you must have a calculator (this is a great model).
A useful, online periodic table can be found at www.ptable.com.
You CANNOT use it on your exams. To do so will be considered cheating.

Lab
Label page 28 in your notebook and in the Table of Contents 5 Signs of a Chemical Reaction Lab.
You and your partner will do a lab showing the different signs of a chemical reaction. Making good observations are important. Generally they should describe how things looked before and then again after. "Blue powder that is the size of sand" is much better than "blue solid". Drawings with descriptions and color are also very useful.
At minimum, you need to record the station, the reaction in both words and chemical symbols and your observations. You also need to explain how you know a chemical reaction has taken place. Stations do not need to be done in order. Directions can be found at each station. If something runs out or is not working, let Ms. Cool know immediately.
Safety glasses must be worn at all times in the lab!

You will receive a copy of fill-in notes. Put these in your notebook on page 27 along with today's date. Label the table of contents.
Take notes while watching the video. Yesterday you should have received 2.07 & 2.08. Continue work on those. I will be back tomorrow and help with anything you are having difficulty with. |

Label page 26 in your notebooks Nuclear Fusion & Fission along with today's date. Also put it in the table of contents.
A worksheet with 2.07 and 2.08 was passed out in class. |

2.04
You'll be given 4 pages for your notebook. Take notes on page 24 using the slides 2 & 3 on the right. The other slides will help you find things on the periodic table. For the uses for the common uses page you will need to look up uses for some of the elements. Once all pages are complete and colored, bring it to me to check off. APP deadline is Tuesday, Sept 29 Late points start after 11:59pm, Wed. Sept 30 |

2.05 - Is the online practice. It will be available starting later on Thursday, Sept 24.
Wednesday - Sept 23, 2015
Label page 23 in your notebooks Atoms, Ions & Isotopes along with today's date. Also put it in the table of contents.
Information for notes:
Atoms are composed of protons, neutrons, and electrons
Elements are different because they contain different numbers of PROTONS
The “atomic number” of an element is the number of protons in the nucleus
# protons in an atom = # electrons in a neutral atom
Charge is determined by adding together the protons and electrons.
Below are Thinglinks - if you hover over them you will get info. You should draw this information in your notebook on page 23.
2.03 - Create an element with your table partner. It will be found in your Google Drive. Your slide number is your table number. Instructions are on the last slide. Slides will be checked the following week after we add our last info to them.

Passed out new table of contents and started it.
2.01 - Complete Unit Cover Page on Page 22. Remember you need the title nice and large, 3 pictures and colored corner to corner. Do not use markers! They bleed through!
2.02 - Build an Atom activity found in your Google Drive. We will continue this into Tuesday.
