Below are excerpts of e-mail conversations between Betty Vail, a physics teacher for Florida’s online high school, and some of her students.
Weekly check-in! Thank you so much for helping me with technical stuff on Thursday. I am so sorry that I didn’t page you the day that you left a message, I was very surprised that there had been a delay with my voice mail.
This is awfully unusual. Anyways, now I finally know where to find my grades:) Thanxs.
Thanks for the update.
I will be away on a site visit today. Just page me sometime tomorrow.
You’re doing a great job in the class. I was just calling to see if you had any questions.
Thank you for your reply & instructions. I don’t have any questions, but thanks for asking - I’ll be turning in some more assignments soon, I’ve just had a hectic week.
In my Lab Design ... I was mentioning that since the ball is in motion, you can’t have as specific of a measurement as you could with other objects that aren’t moving. So, do I want to say to measure to the nearest tenth of a centimeter or the nearest whole centimeter?
You might want to measure to the nearest “half” centimeter. That’s about the best you can do with a moving ball.
