"Would you like to relax your students' tired eyes?  Is it sounds good to convert any written text such as Microsoft Word into spoken words? What about running a PowerPoint presentation and have a narration of the text on your slides? Would you be interested in a list of 19 Free Text to Speech tools?"

Summary via The Scout Report (Apr 2012): "After watching this erudite (and fun) program from NOVA, you'll never again wonder "Where's selenium?" This two-hour program is hosted by David Pogue (the host of NOVA's "Making Stuff" program) and it "spins viewers through the world of weird, extreme chemistry: the strongest acids, the deadliest poisons, the universe's most abundant elements, and the rarest of the rare." It's a fascinating way to learn about the history of the periodic table, and the discovery and properties of the elements. The site also contains fourteen additional features, such as the Name That Element! quiz, an iPad app, a chemical bonds quiz, an interactive periodic table, and an exploration of the "amazing atomic clock." It may make chemistry junkies out of neophytes, and the already-converted will find much to keep them occupied here. [KMG]"
