Play a classic game of I have...who has? with your students. Cut out each of the strips of paper and place them in an envelope. Distribute these strips to students in your class. If you have a smaller class, some kids may receive two strips of paper. Have a student begin by reading the first card. I have included a worksheet that students can follow along with and write down the function of each anatomical structure. You can play the game in 15 minutes or stretch this to a full 30-45 minute lesson by filling out the chart. Have fun!
