Helloooooooo! ** I am out on maternity leave through September. My substitute will be Rebecca Derr-Schriner. Her email address is rderrschriner@kgcs.k12.va.us . Please contact her with any questions or concerns.   -- >   Click here for Course Syllabus *Remember, we are a Canvas based school! So, everything you will need can be found in Canvas. This page is simply here as an extra resource.    7th Grade Life Science The class is your standard 7th grade life science that students take at KGMS. It will cover 11 standards of learning (SOL's) set by the state of Virginia, and the students are required to be tested on the information their 8th grade year. That SOL test will be cumulative and cover information from their 6th, 7th, and 8th grade years. In my class we will cover many topics ranging from living organisms and cells to genetics, ecology, and scientific investigation.     *Remember to have fun with it! Science is anything but ...
