LARN 023 C6D3

Start the following in class:

1. The required journal topic for today, J23A, is:

a.What is the difference between an elemental symbol and an empirical formula? [Hint: empirical formula is defined in the glossary of your text.]

b. Which journal questions have most helped to clarify chemistry concepts encountered thus far?

c. Explain the reason for each of your choices.

2. Study for the summative assessment on chapters 1 and 2 that is to be given on your next school day.  Today is day 23. Study for your test which is scheduled for school day 24! If your class does not meet on day 24, today’s home learning activities are listed under day 24 and on day 24 your home learning activities are those listed below.

  • Go to http://www.phschool.com/webcodes10/index.cfm?wcprefix=cda&wcsuffix=1010&area=view and take an online formative test for chapter 1, Introductory Chemistry. Then click on the Score My Test button and study any topic that you do not yet understand.
  • Go to http://www.phschool.com/webcodes10/index.cfm?wcprefix=cda&wcsuffix=1020&area=view and take an online formative test for chapter 2, Matter and Change. Then click on the Score My Test button and study any topic that you do not yet understand
  • Review and study the Cornell notes and/or Study Guides that you took in and out of class, together with your journal reflections and informational handouts.
    • Also review anything that you previously corrected on
      • the Chapter 1 and 2 Study Guides,
      • the Chapter 1 and 2 Section Reviews,
      • the Chapter 1 [Formative] Test A,
      • the Chapter 2 [Formative] Test A,
      • and any other assignments or problem sets that you have have checked using green ink.

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

1. There is a flow chart summary of one way matter could be classified at the link entitled Interpreting Graphics .  Use the classification of matter flow chart given and answer all parts of the four questions asked in your Learning Log.  Ask for clarification when you get to class, if necessary.

2. Prepare well for your very important summative assessment of chapters 1 and 2!

  • Make sure that you study and review the flipchart entitled Introductory Chemistry U1&U2 until you are sure that you understand all the concepts listed.
  • Study the class notes you have taken and the prepared notes that we have gone over in class. Study what you originally was unclear about on the Chapter 1 Introduction to Chemistry Section Reviews and Formative Test A and the Chapter 2 Matter and Change Section Reviews and Formative Test A.  Look up anything that you still don’t understand in your text, glossary, vocabulary study sheets, class notes, .. or come to help class.
  • Continue to study the meanings of the words on both the chapter 1 and chapter 2 vocabulary lists. Place a – symbol in front of each word that you have to study more, and a change the- to a + symbol in front when you have demonstrated mastery over the word to a study buddy, parent, or friend. Bring your studied and marked up lists to class .
  • Check out the student made Quizlet for chapters 1 and 2 at https://quizlet.com/157152043/honors-chem-chapter-1-2-flash-cards/
    Do all the definitions reflect a thorough and correct understanding?
  •  Study the Key Concepts given on pages 33, and 57 of the text.
  • Study the SI prefixes and their mathematical meanings until you can readily explain the meaning of each listed SI prefix as a numerical multiplier.

3.  If you have time, construct a concept map in the Google Classroom using the Google Doc tools. Please turn to page 57 in your text and construct a concept map relating the ten terms listed at the bottom of the page as today’s journal reflection J23B.

Do not give term definitions; the assignment is to make a concept map showing some of the relationships between the chemistry terms, not a vocabulary sheet.

  • Be sure to draw a circle, oval, or box figure around each of the given terms.
  • Connect related terms with arrows that have an arrow head.
  • Express the relationship between the two terms in a sentence.
  • Think of a verb or verb phrase that relates each subject word at the tail of the arrow to the object or predicate nominative word at the head of the arrow..
  • Draw the arrow from the subject word to the object word to which it is related such that a sentence relating the two terms reads in the direction of the arrow.
    • Check that the subject of each sentence explaining the relationship is shown at the tail of the arrow.
    • Check that the arrow head is touching the geometrical figure drawn around the term which is the object or predicate nominative of the verb that you have chosen.
  • Write the verb or verb phrase that describes the relationship of the subject to the predicate next to the middle of each arrow that connects the two terms.
  • Repeat this process until all the given terms have been connected to at least one other term in a single web of connected sentences.  You may add one or more extra terms such as formula unit if that would make relating terms easier for you to do.  That is, you may add an extra word to your concept map if adding that word allows you to write a sentence showing a relationship between a given word and the word that you added.

When you have completed your concept map, place the electronic copy in your S0x_HonorsChemistry_LastnameFirstinitial labeled folder in your MNSD Google Drive, and then print out a copy of your concept map and bring it to class.
