I quickly ditched that topic and went right to building a web page. Taught them a few HTML tags and they instantly became "webmasters". They were so thrilled. They could create blinking text, could make all the fonts pink. All just by moving around some simple text in NotePad.
Most importantly, they were creating things that they thought were only able to be created by "scientists". I loved how it boosted their own self worth.
I've stopped teaching a long time ago. Not sure if there's still tools out there where a 13 year old kid with no technical experience can immediately get gratification with something so simple on a computer. Maybe it is a time gone by.
