do you know how after a couple generations how is it that people loose the substantial knowledge of the past technologies and attitudes of those who lived before? are you aware of what this causes?

simplistic thing to educate are only from very very early beginners, and it will set them up to fail if not proceeded with proper in-depth explaining/motivating to learn more about it.

good effort, i would advise working on your presentation speed and flow, as well as explaining while doing.

keep an open mind :D
