I’m drafting my pre-class reading quizzes for the summer session. Here is day one. Please comment.
Imagine you are tutoring an 8th grade student in physics. You notice that the student is a little confused about the difference between what is meant by 3:00 pm and what is meant by 3 hours. How would you explain to this student the difference between 3:00 pm and 3 hours?
You are still tutoring this same student, and notice the student is having a similar problem, except now they are confused about the difference between being at mile-marker 72 and having traveled 72 miles. How would you explain to them the difference between being at mile-marker 72 and having traveled 72 miles?
Here is a physics problem! Imagine you are driving a car along a long straight. Your friend in the passenger seat is recording where you are every hour of the trip.
Explain why your friend might reach the conclusion that the speed of the car at 3:00 PM was 24 miles/hour.
Then explain why that answer is probably not correct.
You might have noticed that the table above does not have information about where the car was at 5:00PM. This information is missing because your friend was asleep. What do you think is a good estimate for the mile-marker of the car at 5:00PM? Explain how you determined your answer and why you think this is a good estimate.
Here is one final question to consider. How much total distance did you and your friend travel between 2:00PM and 5:00PM? Why is this answer different than your answer to question 4?
