All children learn by doing things and as adults this continues. The "fun and games" section is exactly what it says, an opportunity to learn. We have tried to include material for a broad range of interests and we will give age appropriate warnings as necessary.
Remember, it is only through exploration and testing ideas do we learn, just as we there is no such thing as failure as a "negative result" still means something new which wasn't know before until it was tested. Then it's possible to try again with a different approach - this is how science works!
