For Tuesday, October 9

Sections 8, 9 and 10: Finish Exercise 2 on the back of your Mole Activity Sheet, if you have not already. Then read the case study titled "Avagadro Goes to Court", which can be found in the 'Homework Documents' section. On Tuesday, you will be given the same assignment as the students in the case study. The way to solve this problem, is very similar to the types of problems you did on your Mole Activity Sheet. You will work as a table, and will have one day to figure out the answer. Come in with a game plan! I recommend you look up the molar mass of Aluminum (measured in grams/mole).  You will be given the opportunity to find the mass of an small, square sheet of foil. Realize that these two measurements (and their units) are major clues into how to solve this problem. Your preparedness, efforts in class and the accuracy of your answer will all be a part of your grade for this assignment.
Think critically! Exercise your brain!

Section 11: Read page 83 in your textbook. Then in your notebook, define 'mole', 'Avagadro's number' and 'molar mass'. Next, read the front of the 'What is a Mole?' worksheet, which can be found in the 'Homework Documents' section and complete Exercises 1 and 2 on the back.
**Note: a light year is a unit of distance, not time. It is the distance that light travels in a year. Since you are given the distance light travels in one second, you can calculate how far light travels in one year.

Thursday, October 4

Sections 8 and 10: Read page 83 in your textbook. Then in your notebook, define 'mole', 'Avagadro's number' and 'molar mass'. Next, read the front of the 'What is a Mole?' worksheet you got in class, and complete Exercise 1 on the back (2 questions).

Wednesday, October 3

Sections 9-11: Using chapter 3 in your textbook, then answer questions 1-8 on page 89.

Tuesday, October 2

Sections 8 & 9: In the green packet you got today, answer the first 3 quesitons on the first page, the 'protons, neutrons and electrons' section on the second page, complete the definitions of isotope and atomic mass (bottom of page 2), draw the models of the nuclei on the top of page 3, and the 'matching' section on page 5.

Section 10: Your 5 re-worked testable questions are due tomorrow. Don't forget you also have your periodic table quiz!

Monday, October 1

Sections 8 & 9:
1) Using the editing and discussions we had today in class, rewrite your 10 testable questions into 5 high quality questions. Remember, the key to a good question, is that an experiment can be designed from it without the reader needing to ask for more information.
2) Under the 'Homework Documents' section you will find a History of the Atom worksheet. Using your textbook and the internet, answer the questions pertaining to Dalton, Thompson and Rutherford. You DO NOT need to do the section on Bohr (we'll get to him later).
