Purpose: this video and discussion are used to give students a chance to do a simple experiment on reaction time to better understand the steps of scientific method. Task: watch Reaction time video to see how to do the ruler drop, answer questions provided below, respond to at least two of your peers’ posts. What’s Needed: computer/device to watch video, chapter 1 in textbook, notebook & pen/pencil to take notes. Assessment (10 points): all questions correctly answered in initial post (+5), response to at least two other peer posts (+2), initial post posted by Wednesday 11:59pm (+2), correct grammar and spelling used (+1).

For this discussion, please watch the video and answer the following questions in your initial post:
1. What factors do you think might make someone have a faster reaction time in the ruler drop experiment?
2. Using one factor that you put in #1 that you can test, construct a hypothesis and null hypothesis.
3. How would you set up an experiment to test this hypothesis?
4. What are the variables in your experimental design:
independent variable(s) =
dependent variable(s) =
standardized variable(s) =
5. Now try it out! What was your result?
