Moko answers these questions as he travels all over the world, discovering many natural phenomena which sometimes delight him and other times scare him. Each of the 52 animated episodes recounts and adventure and ends with an explanation of what seems unexplainable. This series is in both English and Spanish, and each 5-minute video includes extended description which provides introductions to both the story and the science segments. To further enhance the learning experience, these introductions and all other description also have been captioned for the benefit of students who are deaf.
