Unit 2 Review

Friday, January 17, 2020: For the entry task, students are assigned the job of accessing the Swart Chemistry Unit 2 Review Google Doc designed to facilitate the unit 2 review process.  Each student is responsible for:

  1. Selecting one question from the Unit 2 Review section of the textbook (pages 252-256) and writing both the question (including all multiple choice answers), highlighting the correct answer using bold text, and then explaining why the correct answer is correct along with including a page citation from the textbook.
  2. Selecting at least three exercise questions from Lessons 28-48 in the textbook.  The questions are found at the end of each lesson.  Follow the same steps as above.
  3. Note: If all Unit 2 Review questions have been addressed, verify one answer (include your name as the verifier) and then answer at least four questions from Lessons 28-48 in the text.

Tuesday, January 21, 2020: For our first day of review for the Unit 2 Exam taking place on Thursday, we briefly reviewed the vocabulary of chiral, achiral, and dehydration synthesis reactions (encountered in Lesson 34) by visualizing the reaction in the context of amino acids.  Class notes are shown below:

Next, students played a Kahoot! designed to test their understanding and retention of material they had the opportunity to study over the three-day weekend.  After the Kahoot!, students had the remainder of the class period to answer or verify answers on the class Google Doc started last Friday.  All students received a copy of a practice test to complete in class or as homework.  In addition, students were reminded to prepare one 8.5″ x 11″ page of notes (front and back) to use on the exam.

Wednesday, January 22, 2020: For our final day of review before the Unit 2 Exam, we began with reviewing question 18 from the multiple choice portion of the unit 2 review.  Next, students received the answer key to the practice quiz they received yesterday and had the opportunity to ask questions about any points of confusion.  Students had the remainder of the class period to ask questions, share ideas, add to or review the Google Doc, and add to notes that can be used on the exam tomorrow.  Areas of focused study should include:

  • Connection between molecule name, molecular formula, functional group, and smell
  • Larger molecule shapes and smells
  • HONC 1234 Rule
  • Connection between molecule size, polarity, and smell
  • Lewis dot diagrams (lone pairs, bonded pairs)
  • Molecule shape
  • Advantages and disadvantages of types of molecular models
  • Receptor-site theory
  • Electronegativity: calculations, partial charges, dipole, symmetry
  • Mirror-image isomers (chiral molecules)
  • Amino acids: how are they similar? different? R group polarity
