    Greetings, as FUSD plans how to proceed with the remainder of the school year, teachers will be doing their best to communicate and deliver learning content to all students. All students in my APES and Biology classes should be connected to my classes via Google Classroom. For parents interested in checking these out, please feel free to visit them here:

    APES: https://classroom.google.com/c/MzU0MzUxMTU5Mzha   (Classroom Code= k4ypg7x)

    Biology: https://classroom.google.com/c/NDQyMjYyMzk2ODZa (classroom code= iizo5fa)

    *Feel free to contact Mr Krassner at dkrassner@fusd1.org
    Thank you and Stay Safe! 

    Welcome to Mr. Krassner's Website! This year (2019-2020), I will be teaching AP Environmental Science (APES) and Biology classes at Coconino High School. Click on the APES or Biology links on this page to access weekly assignments and other information. I may also use the "Remind" app and Edmodo this year as online tools for assignments. 

    The puropose of this website is to help students and parents stay on top of current topics and classwork during the school year, so please come back to visit as new information will be updated periodically. In the meantime, ALWAYS feel free to contact me at the email address or phone number listed above.

    I am also available most days after school for make up assignments, assisting students with their work and meeting with parents.


    Thank you for stopping by!
