integrates computer games directly into eBooks to improve readers comprehension. Our solution, based on the psychology of how people read text narratives, is to use interactive computer games within books to leverage readers with their internal representations (patent awarded May 2014).

I need to explain water and current to an audience of 9-13 year old.
I have the book text which needs a game so the kids can understand this; Currents in water- deep currents and surface;
1 is the wind for surface movement: westerlies bllowing from W-E and Tradwewind from E to W and , 2 is the density more salt and colder- more dense sinks, 3 Floor, with hills or caves deepwater will go up and down, 4 is Coriolis effect; new motion when it collides with another motion or stationary. I see different parts for the design as the reader/player will get create movement and see the effect, pour more salt or make it warmer or colder...see the effect..etc.

So, if you take on this challenge it will be enjoyed by kids. A good illustration will grasp the knowledge how currents come about. I found some material online but I need pieces which I can use in a game, probably a Construct 2 game. The 2 last images is the style and are the characters in the book/other game parts.
