Seventh grade student Anna Schou said she made $10,000 in fake money off her stocks, including:
"Nvidia, Target and Netflix, things I was familiar with," Schou said. "I'd be interested in doing this in real life too."
Seventh grade student Ava McGahan admits she lost all her money at one point and then rebounded.
"I had a few stocks like Tesla that kind of went wonky all over the place," McGahan said.
"I learned that it's important to spend your money wisely."

A teacher at Los Medanos Elementary School empowers students, builds community and goes viral with a classroom singalong to the Lizzo song "Truth Hurts."
Lynch incorporates real-life examples and teaches his students what can impact the market.
"We talked about different companies and why do you think their price of that stock went up or down, and how it relates to things going on in the world now, from high oil prices to high inflation, etc.," Lynch said.
