Needing a way to show students who can receive and donate blood?
Use this hands-on demonstration/ experiment.
Students will see which blood types can be donated and received.
Answer key is provided along with a handy set-up suggestion page.
This can be done as a demonstration or as a small-group exploration.
Incorporate this during a genetics unit as this is an inherited trait, or as a fun activity on Valentine's Day.
Another version of this is sold for Halloween as "Dracula's Dilemma" depending on how you want to incorporate the lesson based on season/ semester.
