This is a fun and exciting reaction time lab. The students get to work in collaborative groups to test their reaction time after a nights sleep. They will make inferences based on how the amount of time they slept the night prior will affect their reaction time. They will formulate a hypothesis and answer several questions. You provide nothing except yard sticks! The observation data sheet, procedure, lab, and lesson plan are all included. You can even use the mini lesson provided before or after the lab to deepen the knowledge! Enjoy!
