This Teacher's Guide, for grades 7-12, allows students and teachers to explore the world of genomics in agriculture and food. Teachers can use the Teacher's Guide to expand their knowledge of genomics, then couple that with 3 interactive lesson plans that use coding, experiments, Ontario-focused case studies, career exploration and much more. These lesson plans also help students understand genomics in agriculture and food related to the context of animal welfare, food security and climate change. Pair this teachers's guide with a recording of a live event with Michael Dorrington, a geneticist at Ontario Genomics.
