  1. I like the metric system better because it goes in multiples of ten instead of memorizing a different value for each measurement.

  2. Thank you for posting this so soon!It’s really helpful to rewatch parts where I fell behind and didn’t write down all the notes!

  3. The lab this morning was very challenging! If the density we measured wasn’t exactly the density of one of the fruits but was really close, was that okay?

  4. The lab this afternoon was very interesting!
    If the same color blocks had different masses, then how did they all have the same Density range as related on the paper?

  5. I took the temperature of the room today for the SI Scavenger Hunt, and when I looked at the large thermometer on the wall the temperature was over 25 degrees Celsius, but when I used a lab thermometer and held it in the room temperature air, it said the temperature was only 21.8 degrees Celsius. Which should I use?

    • Sarah – a couple of ways. You can type the calculations into your lab, or you can write all the calculations on a sheet of paper and then either take a picture with your phone and paste it into your lab or use a scanner to scan the page into your computer. Either way is okay.

  6. I found going over SI units to be very helpful for communicating my results. For example, im yesterday’s lab, we were all able to communicate our results easily through what we learned throughout the week

  7. Thank you so much for the help session on Thursday! It really helped me better understand density problems. I hope you have a great weekend!
