This week was a week chock full of stuff to reflect on since we did many things like lots of white board meetings and Pogils.  First off on Monday we did a bunch of board meetings on the experiments we did  starting off with the burning steel wool.  My group, except me didn't try to come up with an explanation so they decided to just draw particles on fire instead of any actual reaction (I actually looked this up online and figured it out) and then made me present it because they all agreed that I looked the smartest there fore should present that we had no answer.  But this helped me learn in the way of leadership because then I made sure my group always had an answer and that we didn't talk to much.

We did several of these white board meetings on Monday but none worse than the the first.  Another on we did was the Alka-Seltzers on where everyone got about the same answer about how gas leaked out of the loose lid.  We also talked about the sugar cubes and how we all had almost no change in mass and sometimes everyone just gets the same answers.  My group actually was an outlier on this on because we forgot to but the cap on the scale at first.  We also did the precipitate mass and change and everyone's data was mostly similar to each others with a few being slightly different but made up to human error.

Wednesday we started our day with new seats which I didn't mind and we started our Pogils which as group work meant that we had to actually talk to the people at our group.  Our group reader was Lizzey (I don't know if that's how you spell her name) Bobby our presenter/recorder and Hannah our technician and Me the manger.   Our first Pogil was about how to properly record measurements Lizzey was gone most of the time the rest of us worked very efficiently to finish the pogil and it paid of as we finished time and were able to start the next one the same day.  But  more reflecting, we learned how far out we should estimate and how to estimate. the second one and the harder of the two was the on on sig. figs. and how to identify them.  This one I think was harder because it wasn't a very good explanation of it and some confusing questions, but despite all this my group still worked efficiently and since Lizzey was back we were even more well oiled. We were then asked to put our answers on a white board but since people weren't as fast enough we didn't have enough time to do a whit board meeting for this. After that Lizzey and I were sent to help one of the other groups and we did so successfully and they finished and had learned their mistakes before the bell rang. 

on Friday we did so more learning and review on Sig. Figs. and this was nice to just sit and listen to the teacher explain it because this is one of the ways I learn best in a classroom. We then measured the meniscus of graduated cylinders and had a white board meeting using what we learned from the Pogils to estimate the last digit or two and my group actually got pretty close to your measurements but as you said anyone could be right.
