Monster Physics™ helps your child learn physics and so much more. Spend time on the “learn” page, where parents and kids learn physics vocabulary together. Move through the missions, starting with the “tutorial” level that introduces necessary strategies and tools. There are 50 different missions that can be accessed at any time with enough content available for a long shelf life. “Free build” is a personal favorite for watching kids invent to learn. In addition to all the physics, this app cultivates innovation, strategy, and persistence, which are not skills to be neglected. The full version costs $1.99 and is appropriate for children ages 6-8.
