Start the following in class:

1.  Type the prelaboratory materials for the U10-1M Pressure-Volume Behavior of a Sample of Air laboratory investigation. Read the first part of the document through page 5 and focus on understanding the purpose of the investigation and how that purpose is to be achieved.  Type in appropriate safety considerations, save your version of the electronic document, print off the first five (5) pages of the investigation, and bring them to class.

2. Read pages R32 and R33 on the properties and uses of halogens a.k.a. Group 17 (7A) elements.  In your learning journal record the answers to these two numbered questions, J115A:

  1. What is the most interesting fact you read about?  Please make your answer to this question longer than one sentence.
  2. What makes this so interesting to you?  Please make your answer to this question longer than one sentence.
  3. What is one use for a halogen that you either were not familiar with or were least familiar with? Please make your answer to this question longer than one sentence.

3. For your second learning journal, J115B, read pages R40 and R41 on the properties,and sources of scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, found in Groups 3 through 12 (IIIB through VIIB, VIII, IB and IIB) elements. In your learning journal record the answers to these three numbered questions:

    1. What is the most interesting fact you read about?  Please make your answer to this question longer than one sentence.
    2. What makes this so interesting to you?  Please make your answer to this question longer than one sentence.
    3. What is one use for one of the aforementioned metals that you either were not familiar with or were least familiar with?  Please make your answer to this question longer than one sentence.

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

1.  Study the Key Concepts given on pages 33, 57,95, 121, 148, 180, 206, 246, 280, 314, 346, 378, and 406 of the text.

2. 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.
