Past Documents and Power Point Presentations for Chemistry - Unit 0


*Remember - Students are responsible for ALL classwork, homework, labs, notes, quizes, and tests. Regardless if a student is absent, late, at the nurse, on a fieldtrip, or for any other reason... students are still responsible for all work during the time/days that they missed class. Homework is due at the BEGINNING of class. I am usually available before school, during lunch, and after school (except Mondays and Tuesdays) if a student needs to take a quiz, take a text, do a lab, or ask questions.


NOTE - Late work may be turned in for half credit up until Thursday 10/8 - no credit after 10/8/09.


(In class assignments for 10/5 & 10/6)





--This assignment will be completed in class on 10/5 or 10/6


(Due Mon 10/5 & Tue 10/6 --- Chapter 5)
pg 108 # 1-3
pg 112 # 4-6


(DUE Thur 10/1 & Fri 10/2)
Students will need to use chapter 2 in the chemistry textbook to solve the following two worksheets.




The FIRST TEST will be on Tuesday 9/29 & Wednesday 9/30.

Students may bring one index card of notes to use on the test. Students will need a calculator to take this test.


NOTE: for # 15 change the mass from 86.42 g to be 88.77 g
NOTE: for # 16 change the volume from 54 cm3 to be 5.1 cm3


CORRECTION: - #35 - the standard form for the 5th question should be 268.023 kg = 2.68023 x 10^2 kg

(DUE 9/25 & 9/28)
1) Answer Questions from the textbook - pg 75= #32 - 35
2) Worksheet - Sec 3.1 Measurements and Their Uncertainty (both sides)
3) Complete in class "Practice Worksheet for Calculations and Conversions" (both sides)



(DUE 9/23 & 9/24)
There are TWO homework assignments related to Density
1) Anwser Questions from the textbook . pg 72= # 25,26,28,29, and pg 79 = #60-64
2) Complete the density ranking worksheet that we started in class. (See below)
--Students are to compare the density of several items and rank them accorinding to their denisty and melting point


Students need to understand density (textbook pages 68-71). The following was NOT show during class. But, if you are not familiar with density, this powerpoint may be helpful http://www.worldofteaching.com/powerpoints/physics/DENSITY.ppt

(Sept 14 - 18)

Science uses the metric sytem (SI units) to make measurements



(Sept 1 - 11)

We will be making many types of calculations during the course this year. Please make sure that you understand how to make accurate and precise measurments & calculations to the correct number of significant figures.






We never looked at this PPT during class, but it may be helpful to you.
