These are my favorite resources for Anatomy & Physiology! I've taught the class since 2010, and it's been an ongoing goal to take a class that can be super heavy lecture-based and make it more interactive as often as possible.

Description
Updated 1/21/21!
After feedback about how the lab was more about reaction time rather than reflexes, I re-vamped the lab to actually include reflexes, not just reaction time activities. These are all low-material things you can do with objects that can generally be found around the house.
------
Part 1: Students test their reaction time using a ruler and a website (two different ways of testing the same idea). The website is fun- they have to tranquilize sheep. The only materials needed for Part 1 are a ruler and a partner.
Part 2: Students are asked to define reflex, and then asked if reflexes & reaction time are the same thing. Then, they play with eye reflexes- the photopupillary reflex and convergence- and consider how these are important for keeping us alive. All they need is a flashlight (pen light, flash light, cell phone light) for the first, and an object (as simple as a pencil or even their finger) to focus on for the second.
Part 3 has students research reflexes common in infants. The list of reflexes is provided, but students have to do some digging in order to answer the questions.
This takes my efficient students one class period (45ish minutes) to finish parts 1 and 2, and most of part 3. I assign the leftovers as homework.
