TEACHERS: A film or movie can be an alternative educational experience that highlights points covered by the curriculum. Each Movie Lesson Plan and Learning Guide will help you maximize the benefits that your class derives from watching and discussing the movie.


PARENTS: Watch the movie with your children and briefly talk about its message. Often, just one or two comments will make the film a meaningful experience. Your family will grow closer as all of you learn about history, culture and people. You will gain some positive control over screen time.
 
Lesson Plan Excerpt

To give teachers and parents an idea of what the lesson plan contains we have set out a brief excerpt from the proposed lecture.

To understand how soap cleans our hands (or anything else for that matter), we must review what we have learned about:
(1) how atoms become attached to each other to form molecules; and

(2) how molecules attach to other molecules.
ATOMIC BONDING: Ionic Bonds: When the outermost electron of one atom transfers permanently to another atom, the atom that gains the electron becomes negatively charged and the atom that loses the electron becomes positively charged. The electrostatic force (opposites attract) draws the two atoms together forming what is called an ionic bond. See Figure 2....


The complete lesson plan also contains eight diagrams and a comprehension test/homework assignment. A list of the curriculum standards for the ten most populous states that are satisfied by the lesson plan is also provided.
