Mr. Hanger has been a teacher at Loudoun County High for over 26 years now (since 1987).  He currently teaches A.P. Biology and Honors Biology.  In addition, he has coached the girl's tennis team for 16 years; and the last 8 years has been the boy's tennis team coach.  His educational background includes a bachelor's degree in biology from the University of Virginia, and a Masters of Science in molecular biology from Hood College, with thesis work completed at the National Institutes of Health.  Mr. Hanger has also done work in the field of toxinology at USAMRIID in Fort Detrick for 7 summers. 
Objectives for A.P. Biology:

Unit 13:  Anatomy; grasshopper, frog, fetal pig dissections; human skeleton and heart model. (dissection manuals and specimens)


In addition to the above text references we will be doing lots of lab work including 12 required labs that will

be major topics on the A.P. Exam which is scheduled for mid-May, 2010.

Unit 12: A Survey of the Animal Kingdom; characteristics of the major invertebrate animal phyla and of the major vertebrate taxons.  (selected topics from Chapters 26-33)


Homework: follow the links under staff and calendar.  Labs and papers started in class usually need some time at home to answer analysis questions, and since we do this on a daily basis, these assignments are posted in the classroom.  Please feel free to email me with questions: 
School policy statement due to increased absences:

Students absent for extended illness/flu will be given make-up work upon return to the classroom. Make-up due dates will be discussed with students upon return. Sufficient time will be given for make-up work.
