I think is a very good question. The idea to use the skate board to speak about potential and kinetic energy is a good idea, because it is related to the children world.
The animation is very useful in order to answer the question.
I didn't understand the relation between the point on the map and the question. May be is a good idea to find a skate park in any country and to add it as a point on the map. I add the Caesarea skate park.
I hope you can see the comment and the point on the map with the picture. I don't know why it "disappear" before.
