The Innate and Adaptive Immune System and The Lymphatic System Anatomy and Physiology Review Instructions – Race To The Board • The class will be divided into six separate teams. • One representative from each team will come up to the whiteboard to answer a question (in the PowerPoint) within a one minute time frame. • The first person to write the correct answer on the board wins a point for his/her team. Instructions Continued • The Catch: The students at the board only get ONE try to write the correct answer. • If all students at the board answer the question incorrectly, the first person from the audience (on any of the teams) who raises their hand and answers the question correctly, earns a point for their team.
