Hi I'm also teacher and wanna create such simulations and interactive applications like yours
What's your advices and whats the begining point in order create such applications any tutorials or readings
thank you
I'm not sure what sort of background you have, but maybe the best place to start would be to come up with an idea and try to build it! 
Kyatric has some great Construct 2 youtube training videos that helped me understand picking in Construct 2. Understanding how picking works is really important when you are putting lots of instances of the same object onscreen.
