Why Biology? Biology is a fun topic that touches all parts of our lives – from our food, to our family and friends, to our pets.  Biological concepts help you understand your world and yourself.  


Units:    1.  Cells - structure and function including biochemistry

               2.  Genetics - from the structure of DNA to chromosomes

               3.  Evolution - resulting from mutation and selection

               4.  Homeostasis of biological systems – structure and function of the body

               5.  Ecology – principles of ecology and introduction to global change


Homework:  Is assigned every Monday or Tuesday and collected the next class day (Wed. or Thurs. depending on the schedule).  Late homework is worth ½ credit unless it is for an excused absence.  Homework is always done in one of the Biology journals.

Lab work: Labs occur on block days (Wed. and Thurs.) and occasionally other days.  Lab work illustrates concepts introduced during class.  All work is done in the “Lab Journal”.

Extensions:  Extra credit "Extensions" will be assigned periodically.  Extensions allow student to explore biological concepts beyond the classroom curriculum.  No late extensions accepted.


Exams:  There will be a unit exam following every unit.
