Weekly Quiz.  We will have a weekly quiz this year, in an attempt to help you keep on top of the learning.  The quiz questions are posted outside of my room, as well as here, approximately 5 days prior to the quiz.

See our current unit for your current quizzes.

This week  (December 6th)

You will need to be familiar with the following words for your quiz.

1. Matter
2. Pure Substance
3. Mixture
4. Heterogeneous
5. Homogeneous
6. Solution
7. Solvent
8. Solute


Next week  (December 13th)

For your quiz, you are to list five rules/important reminders when using a microscope.

 

Next week  (December 20th)

Your quiz will be the following two questions:

1. State how temperature affects how quickly a solute dissolves in a solvent, and state an example from our experiments (explain how it shows your point). {3 marks}

2. Name a liquid and a solid from our experiments that did not mix to form a homogeneous mixture. How do you know it was not homogeneous? {2 marks}

 

Next week  (January 17th)

On your quiz you will be asked to state the 5 points of the particle theory.

Here is the answer:

1. All matter is made of particles.
2. Pure substances are made of identical particles; no two pure substances are made of the same particles.
3. There is space between all particles.
4. Particles are always moving, the higher the temperature, the faster they move.
5. All particles are attracted to one another.

 

Next week  (January 24th)

Your quiz this week will again be based on the particle theory.

1. You will be asked to identify substances as “pure substances”, “heterogeneous”, or “homogeneous” based in drawings of groupings of particles.
2. You will be required to explain the reason for your answers.

Example:

 

Next week  (January 31st)

Your quiz this week will ask the following questions:

1. Why is water called the “universal solvent”? (1 mark)
2. Name two methods for removing salt from water. (2 marks)
3. Name two reasons why is it important for humans to know how to purify water? (2 marks)

 

Next week  (February 7th)

Your quiz this week will ask you to define dilute and saturated. You will also have to answer a math problem based on the concentration of a solution.


Next week  (February 14th)

Your quiz this week will ask you to discuss the importance of the knowledge of pure substances and mixtures as it relates to air purification, using fill in the blanks.

 

Next week  (February 21st)

No quiz, we will be starting our unit test.


Next week  (February 28th)

See our next unit for future quiz information.

 

 

 
Assignments.  These are the assignments that have been assigned for this unit.  If there is no due date set, you will not submit it, simply complete it and have it in your binder.

Note:  Dates that assignments were assigned are approximate, as I teach three classes, and not on the same day.

   

Pure Substances and Mixtures Title Page

Assigned: Dec 5th

Due: With Binder

You are required to make a title page for the start of this unit. The page must have the words "Pure Substances and Mixtures" on it and at least four relevant pictures. It is up to you to decide what else you would like to do to it.

 

   

Heterogeneous/ Homogeneous Experiment

Assigned: Dec 12th

Due: With Binder

 

This task involved observing three common beverages with the naked eye, a magnifying glass and a microscope, recording observations, drawing observations and discussion at each stage whether the observations indicated a homogeneous or heterogeneous material.  The worksheet may be found here.
   

Properties Homework

Assigned: Dec 15th

Due: Next Period

This task involved choosing three random objects, then making an extensive list of properties for each of those objects.
   

Mixtures Lab Report

Assigned: Dec

Due: Jan 26th

This task involves documenting the 8 mini experiments performed in class.  The lab report is to be a full lab report, showing all of the standard sections.  This is your big assignment for this unit.  All information (including pictures) can be found here.
   

Particle Theory Note

Assigned: Jan 12th

Due: With Binder

 

This was simply a note shown in class to accompany our discussion on the particle theory of matter.  The contents of this note are very important, and it is expected that you have the five postulates memorized and be able to use them for the rest of the year (and beyond).
   

Filtration Experiment

Assigned: Jan 16th

Due: With Binder

 

This experiment involved filtering a variety of substances and making observations throughout the process.  You need to have the instruction sheet and the completed questions in your binder.  The instruction sheet may be found here.
   

Review Questions

Assigned: Jan 17th

Due: With Binder

In class you were shown 7 questions.  Those questions are to be answered and in your notebook.  The answers are posted here, it is your responsibility to check them to be sure you have them correct.  Please see me if there is anything you do not understand.
   

Saturation Lab

Assigned: Jan 30th

Due: With Binder

This task involved creating a saturated solution of sugar water, then using the measured values of solute and solvent you determined the concentration point of sugar in water.  There were also questions to accompany the experiment, which may be found here.
   

Concentration Calculations

Assigned: Feb 1st

Due: With Binder

This worksheet involved using a mathematical formula (concentration = mass of solute divided by volume of solvent) to determine the concentration of different solutions.
   

Air Purification Questions

Assigned: Feb 9th

Due: With Binder

This assignment was to read two newspaper articles and an advertisement for an air purification system, then you were to answer some questions based on that reading.
   

Distillation Questions

Assigned: Feb 15th

Due: With Binder

These questions were a follow-up to our two day experiment on distillation.  After distilling our salt solution you were to use your dried samples to answer the questions on the worksheet.
   

Dissolve Rate Graph

Assigned: Feb 23rd

Due: Mar 9th

In class you did a series of experiments to compare the dissolve rate of three different solutes in three different temperatures of solvent.  You job is to graph the results in a triple bar graph.  The results may be found here.
