CHEMISTRY – Great job on the lab today. So did you see the Law of Conservation of Mass today? Why not? What are you going to do differently in the lab tomorrow, and why do you think it will work? Here’s the the format for Part 1 and 2 of the lab write up, just in case you didn’t get it in class today: CONSERVATION OF MASS Lab Report. Don’t forget – short classes tomorrow, so you need to come to class moving quick like a bunny!
Miss. Skinner did you grade the lab write ups you let us redo? Because in my lab book my redo write up has no grade on it.
Hey ms. Skinner
Do we need to write a rough draft of part 2 or just go ahead and write it in the lab book?
This helped! thank you very much
Are the lab make-up days still Friday and Monday?
hey cayla she moved it to monday and wednesday
Cornelia – Thanks! 🙂
This was soooooo helpful!!!!!
For the extension question #2 we have to design a procedure to observe the law of conservation of mass with a burning log. how can you burn something and keep all the gases and smoke contained if it needs oxygen to burn?
If the container had enough oxygen, you might be able to ignite the flame long enough to burn the log for a little while. A short amount of time should be enough to prove the theory.
BTW: Good thinking. I didn’t even think about this.
I really have learned alot about the conservation of Mass this week!
this lab really helped learn the law of conservation of mass! it showed and helped explain exactly what it is.
This lab was hard but it was worth it because it made me think all these things through
This lab really helped me understand the Law of Conservation of Mass!
I really liked this lab and applying what we have learned this week!

I liked the lesson today, I didn’t know matter could be changed in all those ways.
I enjoyed the lab that we did this week! Doing it the second time was a lot better than the first. It helped me understand a lot about the Law of Conservation of Mass. Todays class was great, too by the way 🙂
I liked the lab we did this week. It is interesting how mass can transfered in so many ways.
is the lab make up day wednesday?
Dylan – This coming Monday afternoon at 3:30 P.M. and also Wednesday morning at 7:15 A.M.
It was really neat how one little mistake could ruin your final mass!
in the second lab we did it was so weird how if you waited to long the mass would decrease but we finally got it thank you ms skinner!
I learned a lot from this lab!
The labs, we did, were very cool. Hopefully, next lab will be more intriguing.
I learned a lot from the lab this week.
