To Future Employers:

I created this blog to increase my students' access to class notes, lectures, homework, and extra credit.  Because many of my former students were world travelers  and/or ESL students with access to smart phones and other forms of technology, I posted relevant information and video clips allowing them to access material and study without needing to carry a bulking textbook.  

My blog became such a popular course supplement, that I was often reprimanded by my students for not posting material immediately after a class.

Thanks for viewing!

BONUS ASSINGMENTS

Chemistry End-of-Year Bonus Assignment(s)

Create and email 3-5 minute video tutorial relating one of the topics below to the material we covered in chemistry class this year.

A tutorial is a method of transferring knowledge and may be used to give intensive instruction in some subject to an individual student or small group.  Tutorials are more interactive than books and lectures, usually including pictures, diagrams, and other visual aides. 

TOPICS


  1. Scuba Diving Tanks
  2. Safety Air Bags
  3. Breathalyzer
  4. Aerosol Cans
  5. Turbo Diesel Engines
  6. Ipod / Rechargeable battery
  7. Acid Rain
  8. Tarnished Jewelry
  9. Smoke Detector
  10. Carbon footprint
Other – Choose your own topic (you must ask me ahead of time)

Your tutorial must include the following information:
  • An introduction stating what / how the topic is used / relates to your daily life.
  • A summary of relevant background information necessary to understand the topic.
  • A relationship between the topic and AT LEAST three (3) things we have discussed / studied in chemistry class. 

In order for your extra-credit assignment to take affect, you must score a 10 or higher using the rubric below.

OTHER:
Mr. Zehner is supportive of any student willing to do extra work to enhance one’s personal or one’s class’s knowledge of chemistry.  If you have another idea for an extra credit assignment that will promote chemistry, help you study for the final exam, or help the class review for the final exam ask him for approval.




Monday, May 23 - Thursday, May 26

All the material being discussed is covered in chapter 26 of your book.  All students should be able to recognize, draw, and name various organic compounds including, alkanes, alkenes, alkynes, halocarbons, alcohols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, amides, and nitros.
