    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 purpose 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!
