This is a useful resource that I would incorporate into a lesson on VESPR Theory or basic molecular geometry. While lecturing students on the connectivity of different atoms, I could pull up this program and show them how atoms come together to form molecules. I could also use this in a homework assignment by having my students create their own molecules. By doing this, they would show me they understood the basics behind creating atoms.
This would be useful before or during a lesson on titration. It would give the students a preview demonstration of the reaction they would be performing as well as a way to continue practicing these experimetns at home.
A live periodic table would be a great resource for my students when first introducing them to the differences and characteristics of atoms. It is more accurate than having to rely on Wikipedia and more interersting and inteactive than a textbook,
All of these flash animations are useful, but the one I find most helpful is the one on Le Chatelier's principle. This topic is usually taught towards the end of the year and can be difficult for students to grasp. By using an interactive diagram to simplify and explain this process, visual and kinesthetic can gain a better understanding of the principle. It could also be used during a lecture to capture student interest before talking about the principle in more detail.
This website, similar to the molecule simulation, would be helpful to students who are struggling with the concept of the octet rule. While it is somewhat basic, it can still be a helpful tool for visual learners. I would probably demonstrate this application during a lecture on the octet rule to make sure they were not confused by it's clunky layout, creating bonds myself and explaing what was happening throughout the reaction.
