Supplemental material for classroom use. Feel free to download and use in your classes.

Some teachers and many administrators prefer to see the lesson plan set in the "classic" style of Set, Objective, Closure, etc. On this page we provide you with links to our interpretation of the labs and lessons in this format. It is recommended that you "cut & paste" the lesson into your favorite word processor to adjust to your needs. They have all been designed to print as a single page.

  • The overhead for the lab report is a generalized form that can be filled out in class with the help of the students, for any lesson.
  • Spanish pages are indicated with (S) (thanks to, Dolores Perez McDaniel, Loretta Roberson and Roberto Mercado, Ph.D)
  • French pages are indicated with (F) (thanks to and Sophie Clerte)

 Tip: Instead of 4-5 lab reports from a group of students, have them turn in one lab report and have them attach their individual notes. In this way you can calculate a grade based on group and individual work.
