Observe the traffic in a road (e.g., the one in front of your school) every day of the week at different times (i.e., morning, noon, and evening) for an appropriate amount of time (e.g. about 15 minutes). Record the number of cars passing both ways. Determine the time and day of the week that has the heaviest traffic. Explain how heavy the traffic is compared to other days of the week and other times of the day.
