112 Cartoon Elements Make Learning The Periodic Table Fun. These are awesome, incredibly creative. The art is crisp and stunning. This should be in print and a staple of any science classroom! <-- That would have made Chemistry so much fun and easier
Not free, but for those girls interested in science these are great Apps, problem solving whilst having fund rescuing Robots etc. If they are going to be on the computer, better it be science I reckon.
