Lab 4--measuring mass and volume

Today was the final day of our fourth lab where students got to use triple beam balances, digital scales, and graduated cylinders to measure mass and volume. All week the students did well, and got to practice some of the things we have been studying in class in a hands on way. I did lose two beakers to the lab (broken) and one of my digital scales disappeared (I hope it is just misplaced), but I consider the week a success. Students had to pay an OWLSbuck if they did not leave a station the proper way--it did wonders for the lab stations, honestly. I used to charge points, but this method is so much better--it doesn't hurt a grade, but it does reinforce something I think is very important--proper care for equipment. That goes beyond science.

Sweet justice!
