Interactive Science | Dot Diagramming-Understanding The Placement Of Protons, Neutrons, And Electrons
| Dot diagramming is an important bridge between 2 major chemistry concepts- atomic structure and then how these atoms combine into molecules.
At first, students may be timid about this activity. But it begins with a review of things they already know, then gradually builds. By the end, they’ll be comfortably using and applying the method of dot diagramming (also known as Lewis Structure).

Teacher Notes
 |
►A strong set of
Teacher Notes (shown left), including:
- 6 pages of details, discussion, and information. Illustrated with images to keep you clear.
- Divided into 3 easy-to-follow sections: Materials, Beforehand, and Procedure.
- 4 teacher/student dialogues, based on actual classroom
discussion, which gives you a truer feel for the lesson.
- 5 Accessories- things you can choose to include to
lengthen and deepen the activity.
►A one page
Quick Notes document that outlines the lesson. Use this to see just what the essential elements are, or if you find the regular Teacher Notes too descriptive.
►An 11 slide
PowerPoint (shown
right) that will lead you and your students through the activity, and get them started on each section of the handout.
►A 2 page
Student Handout formatted in an easy-to-understand 4 column table. In column 1 all they have to know how to do is count to 18. Columns 2 and 3 prepare students minds for column 4 so that by the time they get there, and are actually doing dot diagramming for the first time, it's no big deal.
►A
picture you can use any way you like to reinforce concepts.

The Best Time
Which is better- to do Interactive lessons at the beginning or the end of a chapter? Which would you guess? In most cases you’re better off using demonstrations at the beginning of the chapter because:
- Demonstrations allow you to introduce a topic with more interest, when it’s really needed, and that causes…
- Less stress and anxiety sometimes associated with a new chapter
- And now you have the rest of the chapter to refer back to the demonstration for review or to show how newer concepts apply
Advantages
Because every one of our lessons has been used for at least two years in a real classroom you know you’re more than a great-sounding idea that might work. You’re getting lessons in which the kinks have been worked out, leaving a consistent flow from beginning to end. You’re also getting a thorough set of teacher notes that reflect what actually happened, and not what we hope or think will. In other words, ours have actual classroom experience, and that is a valuable thing.
We all know what it’s like to try to use a vague or idealistic teacher guide that couldn’t possibly have been tried out before it was typed, because it didn’t work! That won’t happen with our lessons.
