Bonds, Atomic Bonds
Uploaded on authorSTREAM by SkyEarth
Students created animated powerpoints today that illustrate how atoms bond and the difference between ionic and covalent bonds. This is the fourth year that I have done this project with my freshmen. It is a good way to "level the playing field" and to guide students who have never produced a powerpoint so they are not disadvantaged with skills and knowledge of tools. It also provides an enormous help to students in knowing the octet rule and grasping the idea of oxidation numbers. Each time I do it, I am surprised and pleased by the "Oh! I get it!" Surprised because we have completed the lectures and textbook work and worksheets. And while I believe they could be successful on a standardized exam after the lectures and textbook questions and worksheets, it seems that true understanding is not happening there. True understanding is happening during the creation of the animated powerpoint.
I am fortunate to have a technology teacher who leads the class in the explanation of how to create an animated powerpoint. She also knows chemistry and so is able to help the students while they are working.
