An awesome collection of ideas! Here are two of my favorites form the list (click through for the rest):
1. TURN AN iPAD OR (OTHER MOBILE DEVICE) INTO A VIDEO MICROSCOPE. For less than $8, an iPad can be used as a 45x microscope to capture still images or videos from leaves, household objects, insects, or anything that warrants closer inspection. With an $0.80 grommet from a hardware store, super glue, and a 45x power microscope (usually found for less than $5), the camera in the iPad or mobile phone can become a microscope. This is how it works: the grommet (think of it as a ½-inch rubber washer) is glued around the camera opening, and the microscope plugs into it. You can see how it’s done on this YouTube video, step-by-step.
3. VIDEO-MAKING ON THE iPAD/MOBILE. A huge variety of sophisticated video effects can be done on mobile devices — some of which used to require a television studio and entire crew! You can use fun effects like Green Screen MovieFX, an app for iPads, iPhones, and Windows phones, which allows for a color in a video shot live to become a pre-set video. Cinemagram, a new app that allows part of a video to be frozen while the rest of video continues, is also fun to play with. Coaches Eye, which allows coaches or teachers to slow down, mark up (like on ESPN), and comment on student videos shot on cameras or phones works great for assessing videos. And MadPad, a multiple-screen video display that can be crafted into a math, social studies, or vocabulary game is another great tool to play with.
