Monthly Archives: September 2017


  1.  Class discussion on what you learned last class from the activity of melting ice cubes.  How did changing _____  change what you measured?  Why do you think this happened?

2.  I will be able to calculate and compare the density of different objects.  See class notes here:  Real Life Examples of Density and Density notes

3.  Do:  Read section 7.2.  Complete the worksheet p.106-107 for next class.  See copy here:  Sec.7.2 Workbook


Test Analysis and Corrections

  1. We marked the Lab Safety Test
  2. We went over the Review of Chemistry 11 Test and students filled in a Test Analysis sheet to see which learning outcomes they are strong at and which learning outcomes they are weak at.
  3. Bring a folder to put your tests in and store in the classroom.
  4. Go over the Worksheet from last class.
  5. Read the beginning sections of Unit 1 and choose a few practice questions from each section to do.

Quiz and Intro to Factors that Affect Reaction Rate

  1.  Quiz on Rate Law
  2. I will be able to use the principles of collision theory to change the rate of reactions.
  3. Video:

4.  Students brainstormed what they could measure and what they could change in the reaction of Mg with HCl.  In groups of 2-3, choose ONE thing you could change and ONE method of measuring the effects of the change.  Plan out your activity (which we will do next class).

If the ____________ is ______________, then the __________ will _________.  We think this is because _____________.

Plan out what equipment you will need, how you will do the activity (procedure), what you will need to control (keep the same in each experiment), etc…

(example:  If the amount of water added to plants is increased, then the height of the plant will be taller.  We think this is because plants need water to survive.  We will add 10mL, 20mL, 30mL and 40mL of water to plants over 2 months.  We will measure their height each week with a ruler.  We will use the same type of plant, soil, container, location, and temperature.)

Lab: Find the Thickness of Aluminum Foil

  1.  Lab activity:  Find the thickness of a sheet of heavy duty and regular aluminum foil.  See copy of lab here:  What is the Thickness of a Sheet of Aluminum Foil
  2. Quiz on Friday on Metric Conversions and Applying Sig Fig Rules.
  3. On Friday, we will have the quiz and then you will have time to finish the lab write up with your partner.  You will also start the chapter 1 review worksheet
  4. Tuesday:  Ch1 review worksheet is due
  5. Thurs. Ch1 Test.  There will be a mc section and a written section.  The mc section will cover a variety of topics from chapter 1.  The written section will focus on metric conversions, applying sig fig rules and reading scales.

Design an Experiment

  1.  Design an experiment that will involve ice cubes melting.  Choose what you will change and how you will measure the change.
  2. After you collect your data,  answer the following:

If the __________ is ____________ then the ___________ will _________.  I think this happened because ____________________________.  If we had more time, we would __________________.

3.  If you did not complete the column notes for section 7.1, please complete it and submit it.

Rate Law and Integrated Rate Law

  1.  Go over the worksheet on Rate Laws.
  2. For practice:  2010 Free Response Q#3.  See answers here:
  3. For practice:  2008 Form B Free Response Q#2.  See answers here:
  4. Next class:  Quiz on Rate Laws.  It will be similar to the practice questions in that you will analyze data, determine reaction orders, the rate law, the value of k, and the units of k.
  5. I will be able to use the integrated rate law to determine whether a reaction is first order or second order (or zero order).  See notes here:  Integrated Rate Law

Sig Fig Rules and Practice Applying Them

  1.  Fizz Quiz #2 on Metric conversions and sig figs.
  2. I will be able to apply sig fig rules.
  3. See notes here:  Follow Along Notes Ch1 Sig Figs
  4. Activity:  Find the density of water.  Note:  there are two purposes of this activity:  1) to see if you could measure precisely using the equipment available in our classroom and 2) to see if you could apply the sig fig rules to your calculation of density.  How did your group do?
  5. Upcoming Events–
    1. Next class:  we will be doing a lab activity where you will apply these principles
    2. Friday:  Quiz on Metric Conversions and Sig Fig Rules
    3. Tuesday:  will go over ch1 review WS
    4. Thurs Oct 6 – ch1 test.  Your ch1 notes and review WS corrections will also be due this day.

Designing an Experiment – Melting of Ice Cubes

  1.  We marked the worksheet for section 7.1.
  2. Hand in the column notes for section 7.1 and the worksheet for section 7.1
  3. Demo:  What happens when hot water vapour is cooled down quickly when put in an ice bath?  Why did the balloon get sucked into the Erlenmeyer flask rather than inflate?
  4. Video:  Melting of Ice

On sticky notes, students:

  1.  wrote one observation of the ice melting
  2. wrote a question they had after watching the ice melting
  3. wrote one thing they could measure if they were doing this activity
  4. wrote one thing they could change in this activity

Based on the class discussion of these 4 things, students will design their own experiment where they will choose ONE thing they would change in this activity and ONE thing they will measure.  We will finish planning the activity and do it next class.

The planning of the experiment can also be followed with this handout:  Smarter Science

Review of Chemistry 11 Test

  1.  Today, students wrote the review of chemistry 11 test.
  2. Bring a folder or duotang to store your tests, labs, etc…which will be kept here at school.  This way, you can access your work and organize it more easily.
  3. Bring your Chemistry 12 workbook starting next week as we will officially start the Chemistry 12 curriculum!!
