Biological Sciences

My name is Graham Ferrige and I am a Biology and general Science teacher here at Highwood High School.  I have been teaching at Highwood since 1998. 


Students in Biology 20 will explore human body systems—digestive, respiratory, circulatory, excretory, immune and motor—and examine how to maintain a steady, healthy body state. They’ll learn how energy from the sun is transformed into usable energy for cells so that cells can perform daily functions. Your teen will also analyze factors that influence species diversity, describe mechanisms that lead to population changes over time and examine the cycling of matter and the flow of energy in ecosystems by interpreting food webs and ecological pyramids.


From molecular biology to community ecology, Biology 30 builds on a variety of biological concepts. Your teen will examine how genetic information in DNA is inherited and expressed, and they’ll analyze the value and impacts of new biotechnologies and treatments such as genetic engineering and hormone therapy. They’ll study the nervous system and describe how the brain, eye and ear function to sense and respond to the environment. They’ll explain how the endocrine system and its hormones regulate and maintain an internal balance, and they’ll investigate the male and female reproductive systems, including the major processes in human fetal development. Your teen will gain a deeper understanding of ecology by exploring how communities change over time, and they’ll apply mathematical models to explain population growth.
