PHYSICS: Did you remember sig figs? All this SI and calculations stuff will come back to you before you know it. One last thing we didn’t get to in class today – what about sig figs in calculations?
When you multiply or divide, the number in the problem with the fewest sig figs determines the number of sig figs in the answer. When you add/subtract, the number in the problem with the lowest decimal value determines the place of the last sig fig in the answer. And remember, you never go by counting numbers or conversion factors.Don’t forget to show all your work!
Now, let’s see you put it all together in the lab tomorrow! 🙂
Hey guys, I couldn’t get my scanner to work (go figure), so I’m just going to post them here.

Hunter – Thank you!! 🙂
Thank you so much Hunter!
Also, everyone remember that we have the density lab tomorrow! Will, bring everything you need. Everyone else, make sure you have an assigned job!
I’ll bring my stuff. I’m excited about this lab!
I will happily be recorder for how little both of weigh/how much water we add and subtract!
Hey guys! I could help refill the trash can with water.
I will help Claire with filling up the trash can.
I shall volunteer to be a designated mopper!
Ms. Skinner, you said that you needed to see me about the Mystery Tube after class, but it completely slipped my mind. Can I come see you first thing tomorrow morning?
Also, I heard someone say something about needing a converter. I’ll be glad to do that.
It has definitely been a while since I’ve posted on here. I posted in the wrong format and everything.
I will be happy to pour/drain out the water at the end of the lab. But I will definitely need some help.
I will help Jenny empty the trash cans after the lab.
I volunteer to mop! It shall be fun!
I will be a mopper, but if there are already enough then I will do anything else that is still needed.
I will measure things such as amount of water and help fill the can!
Do we bring graph paper for the test tomorrow?
