Mark Home

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,
making observations of the ever-changing face of the sun...and I am a voiceover talent. Come
on in and explore my brain! You'll find it an interesting place to hang out.
