Forces and Pressure

  1.  I will be able to describe different types of forces.  I will be able to measure force in Newtons.  I will be able to calculate the pressure exerted on an object.
  2. Finish the density lab and questions.  If you need more time, you will need to come in after school or on Goal Day
  3. Finish the questions on the handout of section 8.1 and 8.2.  See handout here:  ch8 learning outcomes and notes
  4. Workbook pages for section 8.1 and 8.2 due Wed. Nov.4
  5. Workbook pages for section 8.3 due Fri. Nov 6
  6. Ch 7 and Ch8 combined test Tues Nov.10.

Le Chatelier’s Principle Day 2

  1.  I will be able to use Le Chatelier’s Principle to explain how a system at equilibrium responds to a stress.
  2. Read section II.4
  3. Do:  In-Class assignment    #1 and 2 on a separate sheet of paper.  Explain using collision theory how the number of collisions or energy of the reaction changes,   how the rate is affected, how the equilibrium shifts in response to the change, and draw a graph to show how the concentrations change over time.  See handout (we are doing Equilibrium #2 worksheet) here:  Equilibrium Worksheets

Density again!

  1.  Go over Density Calculations Worksheet and Scientific Method Quiz.  If you would like to do a retest for the quiz, come at 9am on Goal Day.
  2. Go over Section 7.2 Workbook questions.
  3. Continue with the Density Lab.  You may get a bit of time next class to finish up.  Any more time you need will have to be on Goal Day.
  4. Read section 8.1 and begin the workbook pages for section 8.1.

Review of Ch2

  1.  Video:  CCC # 11 “How to Speak Chemestrian”

other interesting website to help you memorize ions and patterns in writing and naming compounds:

2.  Go over ch2 Review Worksheet and do corrections.  I want to see what you have learned!  Please show check marks if you have correct answers and for errors, show what concept you have missed. (due Friday).  See answers here:  Ch2 Review Worksheet Answers

3.  Finish ch2 (organized) notes (due Friday)

4.  Wed:  Quiz on Writing and Naming compounds

5.  Friday:  Ch2 Test

Le Chatelier’s Principle – Day 1

  1.  Review:  Enthalpy and Entropy and how you predict whether a reaction will go to completion (spontaneous), not react, or reach equilibrium.  Finish the rest of the questions on the worksheet that we did not go over in class.  See Equilibrium #1 worksheet here:Equilibrium Worksheets
  2. Video:

  1. I will be able to use Le Chatelier’s principle to predict how a reaction will respond to change.  See block 1 notes here: Le Chateliers Principle Block 1 and Le Chateliers Principle Block 6
  2. Read section II.4 and do a few questions from this section.
  3. Do test corrections for Unit 1.  If you want to do a retest, you need to do your corrections first, do some extra practice, talk to me, and come on Goal Day (Tues. Nov 3, time TBA) to write the retest.

Library Day 4 – Science Fair Prep

Today, we had time in the library to talk to the teacher about our project ideas, to try to narrow our choices or to expand on our ideas.  We started doing background research and making a list of equipment we need.

Students need to arrange time outside of class to meet with their partners to work on their projects.  Some options are:  lunch, after school, Goal Day, Pro-D Days, etc….

By Nov 3, all groups should have a project idea to work with.  Students should begin their data collection over Nov and Dec and finish data collection by mid-Jan.

Between mid-end of Jan, students should write their reports and make their poster display boards.

Presentation of their projects:  beginning of Feb.

 

Writing and Naming Compounds Day 2

  1. Are you up to date?  Any assignments, quizzes, tests, etc…up to Goal Day must be completed by Goal Day.  I will only accept previous work from before Goal Day if you have an I Report.
  2. Quiz – How Good is my Memory?
  3. Mark the writing and naming compounds worksheet from last class using the answer key here:  Writing and Naming Compounds Worksheets Answer Key
  4. Review: Finish notes for chapter 2 and do the chapter 2 review worksheet.  ch2 worksheet
  5. For extra practice writing and naming compounds, see worksheet with answer key here:  Hebden Writing and Naming Compounds review with answers

Intro to Equilibrium

  1.  Are you up to date with all your assignments, quizzes, and tests?  Goal Day is coming on Tuesday, Nov 3.  All assignments so far for Term 1 should be completed by Goal Day.  After Goal Day, I will only accept the assignments if you have an I Report.
  2. Intro to Equilibrium
    1. Here is a list of the learning outcomes for Unit 2: Chemical Equilibrium Learning Outcomes stoplight
    2. I will be able to describe the characteristics of an equilibrium system.  See class notes here:  Equilibrium
  3. Demo:  2 buckets of water, a ladle and a spoon.  By transferring water from one bucket to the other, at what point to they reach equilibrium?
  4. Read section II.1-3 and do some of the questions from each section.
