LARN 027 C7D3

Start the following in class:

1. The required journal focus question, J27ab, for today is :

a. What are the reasons that 70.8 m, 0.0617 m, 95.0 m, 7.70 m, 730. m, and 7.30 x 10² m each have three significant digits, but 730 m has only two significant digits?

b. After studying the handout entitled Using Labeled Unit Conversion Ratios to Solve Problems and the Sample Problem 3.10 on page 91 of the text, I have noticed or learned that ..

 

2.a. Use the PQ5R or SQ5R method to prepare a study guide for section 3.4 of your chemistry text on Density. Read section 3.4 in your chemistry text, pages 88 through 94, 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 3 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.

2. b. Do some formative assessment problems to inform you about the degree of your comprehension and understanding.  Assessment questions are printed at the end of the section that you have just read.  Reflect on your answers.  Make sure that you have understood the major points in the section that you have just read.

  • In your Learning Log use blue or black ink and 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 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.
  • You need to make sure you understand those questions that you find challenging, so you only need to record your responses to questions that are challenging you, so that you can later review what you are learning.  If all problems seem easy to you, record the response to the one that was least easy for you in your opinion.

 

  • Study Sample Problem 3.10 on page 91 and then show your work for practice problems I3-46 (In chapter 3, problem 46) and I3-47.
  • Study Sample Problem 3.11 on page 92, and then show your work for practice problem I3-48a and and then show your work for practice problem I3-48b.
  • In the Section Assessment 3.4 on page 93, read, analyze, and show your work for practice problems I3-52 through I3-56.

Selected suggested responses to some of the formative assessment questions are found in Appendix E [pages R82 through R106 at the back of the text].  After you are finished,check pages R83 and R84 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 those questions, circle the numbers of the questions in the margins 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 the software flipchart entitled Measurement in Science.  Flip through and take Cornell notes as you understand the concepts explained.  Study and review the flipchart and/or your Cornell notes until you are sure that you understand all the concepts discussed..
