Nico & Nor Coconut Star is an app that focuses on force and motion for early learners. The app does an excellent job of making the scientific concept approachable for children and parents. The goal of the app is to develop an understanding of force by using the lever in different positions to complete a specific challenge such as using force to knock over a stack of blocks, aiming the coconut at a bridge, or using a series of ramps to hit a target. The challenges become progressively harder as the challenges are solved. There is a complimentary app called Nico & Nor Ramps Journal which acts as a repository for children to explore and experiment with ramps. This would be an awesome tool for hands-on learning at home, in a school setting, or summer camp. Best of all both of the apps are free!
