Newly updated for better viewing on cell phones and tablets, this site from high school science teacher Andy Allen offers insights into Chemistry, AP Chemistry, Biology, Online Apps, and Other Resources. Selecting any of those topics pulls up a list of resources from Mr. Allen's own classes, including blogs, classroom plans, and other resources. For example, selecting Chemistry produces a drop down menu where readers can view PowerPoints on Atomic Structure and Nuclear Chemistry, Periodic Behavior and Ionic Bonding, and many other topics. Readers may also view Videos about Mole Conversion Problems, Stoichiometry Problems, and other topics. For students of chemistry and biology, educators looking for resources and inspiration, or just about anyone who'd like to refresh their knowledge of basic science, ScienceGeek.net has a lot to offer.
