Curved Lenses

  1.  Go over WB sec. 5.3
  2. Video:  Curved Lenses

  1. Finish Curved Lenses Activity.  Answer the following questions at the end of the lab:  Curved Lenses
    1. What happened to the light rays after they passed through the convex lens?
    2. Why would someone want to use a convex lens?  Give two examples.
    3. What happened to the light rays after they passed through the concave lens?
    4. Why would someone want to use a concave lens?  Give two examples.
  2. HW:  Work on Science Fair projects!  You should be collecting data.  Remember:  as a goal, you should aim to finish collecting data by around mid-January in order to give you time to write your report and make your display.
  3. Video:  Mythbusters

and

Lab 20C

  1.  Today, we did a titration lab!  Find the molarity of the HCl.

  1. Finish ch3 and ch4 review worksheets for January. (Mon and Wed)
  2. Ch3 and 4 test (the rest of it) will be in Jan when we return.  It will focus on stoichiometry, limiting reactants, and reactants in excess.

Convex and Concave Lenses

  1. Video:  Concave and Convex mirrors

  1.  Finish Lab activity:  Convex and Concave Mirrors by answering these questions:
    1. What happens to light when it reflects off a convex mirror?
    2. Why would someone want to use a convex mirror?  List 2 examples.
    3. What happens to light when it reflects off a concave mirror?
    4. Why would someone want to use a concave mirror?  List 2 examples.
  2. Mark sec. 5.2 workbook questions.
  3. I will be able to explain how light refract as is passes through a convex and concave lens.
  4. Activity:  Convex and Concave Lenses.  Draw 2 diagrams and label them.  Answer the questions:
    1. What happens to light when it refracts off a convex lens?
    2. Why would someone want to use a convex lens?  List 2 examples.
    3. What happens to light when it refracts off a concave lens?
    4. Why would someone want to use a concave lens?  List 2 examples

Lab 16E

  1.  For bonus marks, identify the cation and anion in the 2 unknown solutions.
  2. Unit III (sections 1-5) Test outline:  30 multiple choice (half related to precipitation and the solubility table;  half related to vocabulary, molarity, concentration of ions, dilution, electrolytes, etc.)  Written section:  one calculation-based;  one precipitation-based question.

Concave and Convex Mirrors

  1.  I will be able to explain how light reflects off a curved mirror and give examples of how they are used.
  2. Activity:  Concave and Convex Mirrors (draw light rays reflecting off a convex and concave mirror.  Label your diagram)
  3. Read section 5.3
  4. Do:  Workbook pages for 5.3
  5. We will mark WB pages for section 5.2 next class.

Limiting Reactants and Reactants in Excess

  1.  Hand in Lab 4C
  2. Warm Up:  you are making goodie bags for friends and want to put 2 Santas, 10 bells, 6 candy canes, and 16 choc kisses.  You buy 62 Santas, 200 bells, 143 candy canes, and 312 kisses.  How many goodie bags can you make?  What will you run out of first?  How much extra of each other yummy goodie will there be?
  3. POGIL:  Limiting and Excess Reactants
  4. Demo:  how to do a titration
  5. Read section 3.7 and 4.6 and Do:  #3.65, 3.71, and 3.77  and #4.67 and 4.69

Refraction -final day!

  1.  Hand in your Journals.

Video:  This is not a Rainbow:

  1. Go over Workbook section 5.1 answers.
  2. Finish Refraction activity and hand in.
  3. Read sec.5.2 and workbook pages for sec.5.2
  4. work on science fair projects.  If you need equipment before the Break, let me know asap.
  5. Interesting reflection/refraction video:
