In high school, my team invested our fake money in our Economics class in Amazon.com, right before the stock split. The three of us couldn't have been bigger slackers (we all read and watched movies), but we won the trip to NYC to do all the things you do in an Economics Class. The World Trade Center was nice to visit, in hindsight.
I had a similar project in my high school consumer finance class. Pick a stock and report on it.
I picked this no-name company that had just IPOed because I had recently bought their 16K RAM card for my Apple ][. And their Olympic Decathalon game wasn't bad either.
Too bad I didn't have $1K lying around. I was saving for a Macintosh.
