PowerPoint: Showing Chemistry Bigger Than Life By Ken Costello Text in this yellow box are comments about the animation techniques used. Text in the scroll boxes are what I normally say when the slide is showing. Samples of PowerPoint animations from various presentations. To learn the techniques, run the PowerPoint and then stop it after each slide to examine the Custom Animation Window. Bring up the window by going to the SlideShow pull down menu at the top of the screen and then choosing “Custom Animation…” Click on the animations listed to see its name, the speed, how it starts, and other properties. Click the small down arrow to the right of the animation name to bring up Effect Options window. To start the PowerPoint on different slides, either click the small projector screen icon at the bottom left or press Shift-F5. Elements are the new building blocks Hydrogen Nitrogen-7 Oxygen-8 Carbon-6 The animation is done with the Circle Motion Path for single electrons and the Spin effect for pairs of electrons. Pairs of electrons are grouped first. The Fill effect with transparency is used for the spherical boundaries. Hydrogen Hydrogen Carbon-6 Hydrogen Hydrogen Compounds are two or more elements that share electrons or have taken or given electrons away. Again, the Circle Motion path is used for single electrons, and the Spin Effect is use for pairs. Hydrogen Hydrogen Carbon-6 Hydrogen Hydrogen Compounds are two or more elements that share electrons. Here the idea of sharing electrons is presented with electrons that are following custom motion paths (curved type) When electrons are shared, they don’t just stay around the element that first owned them. H H H N C O Elements are the new building blocks O H H C H C H Let’s build ethanol from the water and methane. Note: this isn’t how ethanol is made, but you can see the building block approach. Straight line motion paths are used. Most started as “Right” Paths because that was the general direction. You can then move the end to wherever you want.

They are built from only carbon atoms and hydrogen atoms. The number of carbon atoms determines what we use them for. If we use oxygen atoms, we can make lipids. H H H N C O O C C N O H HH Ammonia Acetic acid Vinegar C H H H Let’s look at ammonia and acetic acid and how the proton from acetic acid may go to ammonia to make ammonium ion Here I’m using circle motion paths and custom motion paths (curved type). H H H N C O Amino acids are building blocks for proteins O C C N O H C H Amino acid Glycine C H H Alanine S Glycine is the simplest of the amino acids. Let’s now make alanine. Sulfur is needed for two of the essential amino acids. H N C Amino acids are building blocks for proteins O C Glycine S H O H C N O H C H H H H H O C N O C H H Glycine Amino acids connect as a water molecule is released. The “Down” motion path was used for water, then adjusted by moving the end. Glycine came in using the “Left” path. . the slide is showing. Samples of PowerPoint animations from various presentations.
