What Affects Reaction Time?
In Investigation #1, you may have noticed that people have different reaction times. Through your research, you have learned how the senses and the brain communicate to cause reactions. What human characteristics or environmental conditions do you think might affect how fast someone can react? In Investigation #2, you will identify a reaction time question to explore. Do your experiment following the steps below: 1. DECIDE on a research question. RECORD it in your science notebook. 2. DESIGN a plan to conduct your investigation. 3. CREATE a data table in your science notebook that will help you keep your measurements organized. You will also want to record any unexpected observations and questions. 4. CONDUCT your experiment. Collect and record data for each trial in your notebook. 5. CALCULATE the average time it took for each subject to catch the ruler. RECORD the average reaction times for each subject in your data table. 6. DRAW a bar graph that compares the average reaction times
