Why do we have day and night? Why is the winter cold and summer warm? Why is the moon sometimes shaped like a banana? Not so easy to explain.
But now children can find out themselves: in Jeffy’s World, a playfull serious app for children and parents.
Jeffy is a funny, but a little short tempered character that needs your help. By helping Jeffy, you discover how time, seasons and the movement of the world are interrelated.
Jeffy’s World contains:
-3D models of the world, the Sun and the Moon
-12 short animations
-interactive info graphics explaining the seasons and the appearance of the moon.
-Visualization of how a year, a month and a day come to be.
-extra information for parents
The Jeffy-series let’s 6+ kids learn the stuff they want -or need- to know in a fun, interactive way. It helps parents to answer their children’s’ questions and enables them to play and learn together.
Jeffy’s Apps are created by Qlvr, a Dutch studio specialized in educational apps and serious games.
Meet Jeffy and his friends. Enter Jeffys World!
Note: This app is meant to explain how the interaction of Earth, Sun and Moon cause our days, months and seasons to younger children. With that in mind certain simplifications have been made. In the upcoming update a few features will be added so that there can be no confusion that the angle of Earths axis changes with respect to its orbital plane, because of the movement around the Sun. (and that its not tilting back and forth)
