Now that's education.
Your kids are lucky to have a chance to learn hands on like that. School should be more like this and less like obedience lessons. Most kids are hungry for information and are naturally curious.
It's sad that the school that is supposed to be educating them is making learning new things into a chore and destroying children's curiosity.
Anything the government bureaucrats touch, dies. If you want really smart kids ready to succeed in this world, like many things, you need to do it yourself!
