An APP that I find very useful is Molecules, its free and easily downloadable onto your iPAD. The great thing about this app is that it allows students to visualize molecules in 3-demensions. By doing this students are then able to visualize first hand molecular bonds - an area research shows is filled with student misconceptions. This app is great for all senior science class from Science 10-Chem. 30.
Brains!!!! In our Biology classes students must learn not only what our brain does but the various parts of the brain - cerebrum, cerebellum etc. However, being able to see these parts has always been limited - now we have a wonderful FREE app at hand!!! BRAIN - 3D
