Today was the first of what I call a "Friday Forum." I told students they can ask me any tech related question and I'd do my best to answer. Questions like "When was the first ... " I just had them go to Wikipedia for the answer (shhh, don't tell the Social Studies teachers).
I loved the questions about how Youtubers make money. A few students asked about how much math is required to be a programmer. The most popular question of the day was, "What is bitcoin?" I did my best to answer. I explained how all currencies are agreed upon values and mediums of exchange, then went on to explain if you have $10,000 in cash and it burns partially up you can send to to Fed for a replacement or if it's stolen, your bank account is FDIC insured. If your bitcoin hard drive is corrupted, you are simply out the money. I talked a little about how even powerful home computers barely cross the break even point in mining vs. electricity costs.
To end the day I opened an old computer, explained what the important parts were, and had the students practice installing RAM. Most had never seen the inside of any computer.
