“Toca Lab” is developed by Toca Boca AB. In this app, you begin with a single element from the Periodic Table of Elements. You perform a variety of experiments to change the element into another element. As you discover new elements, you begin to fill in the missing elements. This allows your child to experiment on the elements by using electricity, water, chemicals, spinning, heat, and ice. Depending on which type of experiment you use determines what the elements changes into.
It is $2.99 to download and has no in-app purchases. It is compatible with the iPad, iPod touch, and iPhone and requires iOS 5.0 or later.
