A journey through time where each event is documented with social and historical context, several images, an illustrative timeline and little-known interesting facts. Custom made animations bring those events to life, creating an interesting, immersive learning experience. An imaginary clock will guide you through this quest, proposing a simple analogy: the entire Universe started 24 hours ago. The Big Bang, the source of time and space, is the first event in our journey – the clock reads 0:00 hours. Today, 13.7 billion years later, the clock reads midnight. In between is a sequence of key events that has brought us to where we are today. Explore them, place them in perspective, see how they relate and understand the connections. We invite you to take a step back and see the whole picture. :::: REVIEWS :::: “...a beautifully executed lesson on the history of the universe and the evolution of life on earth.

Experience science with experia kids! Experia Kids turn chemistry and physics into loads of fun. Children practically gravitate to the iPad but most of the Apps available for it are not child friendly. With Experia Kids you can be sure that your child is not wasting its time on the iPad but actually learning something. And its fun, too: Your child can create a fire dragon, learn to layer water or grow zombie hands! Experie Kids has been categorized in two ways. There are categorys that are looked after by little patrons. And then there are levels of diffizil ranging from „easy“ to „only with a grown-up“. The Apps special features are: ⁃ double categorisation in categorys and diffizil (easy, medium, hard, only with a grown-up) ⁃ over 50 experiments ⁃ make a video of your successful experiment! ⁃ Step by step instructions with lovely detailed illustrations ⁃ easy to understand explanation for children Many thanks for the great ratings: ⁃Experia Kids comes up with many new, surprising and informative experiments.
