For my project I will be figuring out if a person's reaction time varies depending on the time of day (morning and afternoon). The problem in this experiment is to determine whether a person’s reaction time changes depending on the time of day morning and afternoon.

You did a great job exploring how the time of day might affect reaction time, and your experiment was very well organized. Your data tables and comparisons clearly showed the differences between morning and afternoon performance, and you explained your findings in a thoughtful, easy‑to‑understand way. I also like how you reflected on what you would improve next time. Great work investigating a real‑world question with careful testing!
