Teach the genetics of ABO/Rh blood types and understanding of antigens and antibodies! This includes instructions for making 8 different red blood cells and 3 different antibodies. It also includes lesson plans/scripts for their use (4+ lessons), a student study guide, a quiz, and answer keys. The models are designed to be printed in black and white on 8.5x11 colored cardstock paper, and then have magnets attached so they will stick to your whiteboard so that you and your students can manipulate them. I laminated mine and have been using the same set for years!
I presented these materials in a session at our state science teachers' conference - they were very well received! Enjoy!
