LARN 106 C27D2

Bring in one empty aluminum soda, tea, or juice can to use in your next laboratory investigation.  If you have extra empty aluminum cans and wish to donate them for use by other students, please feel free bring them in.

Start the following in class:

1.  In your Journal notebook write your journal entry, J106, on sheets of three holed 8.5 inch by 11 inch ruled paper.

  • In the upper right corner white space of each upward facing page, use a blue or black pen to write your hand in number within a circle followed by your name. 
  • To the left of the red marginal line, print J106.
  • Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.
  • The required journal focus topic, J106, for today is: In terms of randomly moving particles of a gas, the pressure exerted by the gas is directly proportional to the number of molecules of the gas striking a given area with a certain average force per unit time.
    1. To what is the absolute temperature of a gas in kelvins directly proportional? 
    2. Clarify the reasoning that justifies your statement of proportionality by using one or more examples.  Please make your answer to this question longer than one sentence.

2.a. Use the PQ5R or SQ5R method to prepare study guide for text section 13.1 on The Nature of Gases or go to https://socratic.org/chemistry  to research the topics brought up in section 13.1 of your text.  Read section 13.1 in your chemistry text, pages 384 through 389, and as you do, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet.    You may record vocabulary entries in the body of your study guide, or you may check them off on the chapter 13 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.

2.b.  Writing in blue or black ink, place your hand in number in a circle followed by your name in the upper right white space of a piece of three holed composition paper in your learning log that hasn’t been written on.  Place the page reference for the problems to be considered to the left of the red marginal line on the first blue line.  Centered on the first blue line, write a descriptive title for the learning activity such as Section [chapter #.section#] Responses.  Before you write your response to each question or problem listed below, write its designation to the left of the red marginal line as listed below, followed by your response in ink to the right of the marginal line.

  1. Study Sample Problem 13.1 on page 387 and then show your work including all conversion ratios for practice problems I13-1 (In chapter 13, problem 1) and I13-2ab.  [If you need a refresher or assistance in writing conversion ratios and showing your work, please read through pages R66 and R67 and study how the conversion factors were selected, and set up so that the units in the problem divided out to yield the units of the sought for quantity. Note how the work shown completely explains how the six problems given on page R66 are solved.]
  2. In the Section Assessment 13.1 on page 389, read, analyze, and show your work including all conversion ratios for practice problems I13-3, I13-4, I13-5, I13-6ab, and I13-7. 
  3. After you are finished, check page R93 of the text and check each of those problems that you can by writing in either a check mark (√) or a correction in green ink as we do in class.  Some questions do not have a suggested response given.  For each such question, circle the number of the question in the margin of your notebook paper and check your response with that of your classmates when you come to class.

Recommended for those who have time left in their 45 minute study period, but not required of all: 

1. Download and open the Unit Learning Objectives for Cornell Notes document, press and hold the CTRL key while typing F to bring up a search (find) box.  Type in Chapter 13 in the search box and then move your cursor into the text area to the right and click there to see the first page of objectives.   Consider each learning objective as you proceed through the chapter with the aim of being able to demonstrate your understanding and ability to apply the learnings.  For now, study and take Cornell notes on objectives 4 through 15.  

2.   Download current ActivInspire unit flipchart by logging on to the MNSD Google Drive and selecting it from the Student Resources > ActivInspire  folder.  Generally the flipchart name will begin with a capital U to designate the chemistry unit of study and end in a relatively high version number following the v at the end of the flipchart’s title.

Download the flipchart on the States of Matter & Intermolecular Forces after clicking on the following link: States of Matter & Intermolecular Forces_Including Gases.  Click through the chart quickly and take Cornell notes on concepts pertaining to the learning objectives that you are studying.  At the end of your study, write a summary statement of what you learned.  

[If you have not yet successfully installed ActivInspire software, use  https://drive.google.com/open?id=0B9ft9hAr_RjiR0pqTUpHb3QyMm8  to download and install the latest version of ActivInspire free personal edition software on your home PC, Mac, or Linux computer.]

3. Review those concepts that we have discussed in class that are in your study guides, that are in your text study guide at the end of the chapter, and that on the chapter vocabulary sheet provided to you that describes what is a substance, an element, a compound, a coarse mixture, a colloidal suspension, a solution; an atom; a formula unit, a molecule; a phase, an aqueous phase; a chemical change, a physical change;a chemical reaction, a reactant, a product, a word equation, and a formula unit equation; and how are these concepts different? You need to be able to explain the meaning of each of these terms, and be able to differentiate the terms, be able to compare and contrast these related terms, and give examples that make clear the points that you are trying to explain. Go over each of these concepts with your study partner.

4. Review the SI prefixes and their meanings until you can readily explain the meaning of each listed SI prefix as a numerical multiplier.
