7 Life Science

Welcome to your page for 7th grade science information at St. Paul’s Academy! This year is all about life. We will look at cells through microscopes, learn about how they grow and divide and go hands on with the blueprints of life, DNA! We will study classic inheritance patterns ala Gregor Mendel and research genetic diseases. We will examine evolution and practice classifying organisms according to Linnaeus’s hierarchy. We will journey through each of the Kingdoms of life and wear our safety goggles on the way!
