With funky modern illustrations, TinyBop invites kids to play with the six classic simple machines (lever, screws, wheels and axles, inclined planes, wedges, and pulley) and make adjustments (like moving the fulcrum on the lever) to see how the action changes. Each machine has its own unique scenario (knocking down a castle, breaking up icebergs, lifting heavy objects) and the option to "peel back" the top layer of the animation to get a closer look at what's going on with each adjustment made (lines trace trajectories, arrows illustrate the amount of force needed, etc.). No time limits, no right or wrong answers, just a chance to experiment and play in this well-designed app. Available on Google Play through the Tinybop Explorer's Pass subscription.
