This lab activity allows students to figure out if blinking is voluntary or involuntary (you will need to teach about voluntary and involuntary muscles prior to this activity). There are 3 sections in this lab- how many times do you blink per minute, how long can you go without blinking, and measuring blinking as a reflex. Required materials: stopwatch, clear plastic page protectors, and cotton balls. Students always have fun with this lab. Enjoy!
