This special online-only edition of Exploring takes a closer look at the sweet lure of chocolate. We'll examine the fascinating -- and often misreported -- history of chocolate, follow the chocolate-making process, and take an online visit to a chocolate factory.
Explore the surrounding sounds that everyday objects make. Build a noise contraption from these objects, then add a PicoCricket to automate your contraption. Finally, add a light sensor and program your sound automata to "play" when triggered by light.
