LARN 107 C27D3

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.a.  In the upper right corner white space of each upward facing page of your Journal notebook, write your hand in number within a circle followed by your name. 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 days paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.  For today’s journal entry, J107A:

  1. Sketch and label a diagram similar to Figure 13.3 on page 388 of the text.
  2. Use the diagram to explain how the distribution of the translational kinetic energies of molecules in an enclosed sample of gas varies with increasing temperature. Use examples to clarify the ideas that you express.

1.b. To prepare for your journal entry J107B, read pages R6 through R9 on the properties and uses of the alkali metals a.k.a. Group 1 (IA) elements. In your learning journal record the answers to the questions asked below. Please make your answers to all questions longer than one sentence.

a. What is the most interesting fact you read about?  Please make your answer to this question longer than one sentence.

b. What makes this so interesting to you?  Please make your answer to this question longer than one sentence.

c. What is one fact about an alkali metal that you either were not familiar with or were least familiar with?  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 13.2 on The Nature of Liquids or go to https://socratic.org/chemistry  to research the topics brought up in section 13.2 of your text. Read section 13.2 in your chemistry text, pages 390 through 395, 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.

  • In the Section Assessment 13.2 on page 395, read, analyze, and explain your work for practice problems I13-8, I13-9, I13-10, I13-11,I13-12abc, I13-13, and I13-14.
  • 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 chemical quantities after clicking on the following link: The Nature of Matter.  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. Do the Home Inquiry Activity entitled Observing Gas Pressure that is described on page 384 of your text.

  1. Before you start,gather up all the materials needed for the activity that are listed on page 384 under the heading of Materials.
  2. After you have finished the activity, set up a Home Inquiry response sheet like the ones we have set up in the past to record your responses to Think About It questions.
  3. Then answer the first two Think About It questions asked on page 384 concerning the activity that you performed.  [One fluid ounce in a kitchen measuring cup is the same as 29.57 mL.]
  4. Draw a labeled diagram of the inverted glass, water, index card, and use small labeled arrows to indicate the forces exerted by air pressure.
  5. Answer the third question and refer to your labeled diagram as part of your response. [Hint: If you need help, reading and thinking about the information in section 13.1 on The Nature of Gases might help you to better understand what happened.]
