Science teachers take note of this amazing app. Bobo Explores Light is a great example of how an app can let children aged 7-up play with -- and better understand -- an abstract concept; in this case light. What better way to understand how light changes when it hits a mirror, than to let a child manipulate the mirrors. Other noteworthy content includes a schematic of an eyeball, a conversation with Thomas Edison, and an experiment on mixing colors of light. Organized as an ebook, the 21 page (or screen) app covers a range of light-related topics, starting with the sun, and ending with fireworks. Each screen contains three pull tabs that lead to videos, facts, and definitions. The best part about this app is the way that it lets children directly manipulate the concepts, so they can "try the ideas on for size." See the demo, at http://youtu.be/G0LIP7pl08w. The app was created by Juraj Hlavac at Game Collage, LLC., with text and research by Bob Tedeshi (Craig Fusco) and illustrations are by Dean MacAdam. Game Collage also produced The Three Little Pigs and the Secrets of a Popup Book.
