Meet Mr. Vu
High school science teacher and the person behind Green Flask Science™.
Why I make this
I teach high school AP Environmental Science and Chemistry. Everything on this site started as something I needed for my own students: a simulator that shows what a graph only describes, an activity that is not the same worksheet every teacher has already seen, a quiz bank that is actually fair.
When it was not there, I built it. When it worked in my classroom, I put it here so other teachers could use it too.
How I build
Activities you have not seen
Every activity is written from scratch, with a simulation, a card sort, a lab, or a game, rather than a recycled worksheet.
Quizzes checked for bias
Each quiz is checked for answer-letter bias, so the right answer is not always the longest or always C.
Built to run the year
Full units come with teacher guides and day-by-day pacing, so a week of class takes minutes to plan, not hours.
Try before you buy
The simulators run in any browser with no login, and many have a free paired activity, so you can see the quality first.
