Tumbledown Mtn. Maine

    Welcome to Earth and Its Environment!! 


    I’m Mrs. Cassel and I am here to help you in any way I can throughout the year.  I am originally from the Upper Peninsula of Michigan which means they call me a YOOPER.  I like to spend most of my time outside biking, hiking, camping, running, fossil digging, etc. 



    I graduated from Miami University of Ohio with a Fine Arts Degree, but then went on to Millersville University to obtain my teaching degree in.  I have since earned my Masters Degree through Lebanon Valley College. As of '09 I am Nationally Certified by earning my National Board Teacher Certification.  My husband also teaches here as a Biology teacher and I have two children, Elliot and Avery, who you will hear me talking about not to mention our beagle “Henry”, five rabbits and some chickens.

This site is meant to help you if you have questions at home, however, I may not always be able to keep it up-to-date. I suggest you write down all assignments in your agenda book throughout the year to help keep you on top of due-dates.
