Hi! Welcome to my new website! My name is Craig Karlen, and I am happy to be starting my 11th year at Central.

Here is an old, very serious picture of me.

BONUS: There are two mix-ups in this picture. Can you find them?

(answers at the bottom, make sure you read the whole page!)

I live in Minneapolis with my wife Liz and our two sons, Jack and Alex. I will find a good picture of us soon! 

I love teaching chemistry even though I was a biology major in college. I'm happy to tell you more about that soon. But for now, feel free to use this website to see my schedule, and as the days go by, I will update 'Do Now' questions for the day and post any relevant homework assignments.

The best way to reach me is to email craig.karlen@spps.org. I look forward to working with you soon!

Thanks, 

Mr. Karlen

(BONUS ANSWERS: the word 'iMac' is backwards, and I have a lot more grey hair now than I used to. Did you get those?  Gold star for you!!!)
