My name is Mark Rosengarten. Many of you may know me as that crazy chemistry teacher who
has all those great videos on YouTube, chemistry songs and the host of Regents Review 2.0.
There's more to the story than just a crazy chemistry teacher. I also enjoy chasing storms
and doing nature photography! Come on in and explore my brain! You'll find it an interesting place
to hang out.
ALL OF MY LESSONS ARE AVAILABLE ON YOUTUBE!!
