I am looking to redo my Animal Science Curriculum. Currently, my units are broken up as followed: Unit 1: breeds and characteristics, Unit 2: parts and judging, Unit 3: Reproduction, Unit 4: Nutrition and Digestion, Unit 5: Health and Disease, Unit 6: Milk, Egg, and Meat, and Unit 7: Management Cycles. How do you break your units up? I am thinking about having units based on animal instead of units like this. Any suggestions would be helpful! Thank you!
