What's Your Blood Type?

In this activity, learners perform a simulated blood test procedure. They perform control reactions and test reactions, then use their observations to determine the blood type of different "suspects." This activity is currently used in the Crime Scene Chemistry unit of Oregon Museum of Science and Industry's Chemistry Lab, but can be adapted to other educational environments, including a home chemistry lab. Cost estimates are per 100 learners. For safety reasons, this activity works best as a demonstration for younger audiences.
