Following the lesson on human visions, we turn our attention to the reflexes and reaction of our body. Reflexes are the instinctive reactions and movements of our body to the stimuli while reactions are the conscious decisions we make to the stimuli. The reflexes are almost instant, but when we are reacting to the outside world, the reaction time is different for everyone. We are going to explore the this topic by experimenting some reflexes of our body and using reaction tests to measure the reaction time. The Reflexes we experiment are: 1. Experimenting Knee Jerk Reflex; 2. Experimenting Blinking; 3. Experimenting Pupillary Reflex; The Tests we conduct include: 1. Visual test, the students are to grab the ruler as soon as see it is released; 2. Auditory test, the students are to grab the ruler as soon as they hear the word "released" while being blindfolded; 3. Tactile test, the students are to grab the ruler as soon as their non-dominant shoulder is touched while being blindfolded

I think this lesson went pretty well, but we were a little ambitious about how much we could do in an hour. My group barely made it though the three reaction tests with the dominant hand. I was proud of my group for calculating their averages by hand!
