[Channel-talkchemistry] Reactions in Chemistry workshop #7
The theme is classroom climate and student teacher collaboration. Mr.
DeGennaro did an excellent job mixing humor with student driven problem
solving. Developing general solubility rules from a reference chart of over
100 reactions is a very good idea. I think the student understand where
these rules come from and I think they will better understand how to use the
rules. Ms. Berryıs water and soil activity is another good example where
students have to depend on each other for information and ideas on how to
interpret and process that data. We have a block schedule an 88 minutes is
enough time to do activities that require students to leave school to
collect data. My physics students and I are going out to the football field
to drop egg carrying devices out the press box window. One of the other
science teachers took her students to the local cemetery to collect data on
the people buried there. With all of these ³field trips² students get to
interact differently than the typical classroom setting. In each case
students enjoy the activity and concepts developed. I have to make sure
students stay on task and everyone is contributing. An other out door
activity is one in which my physics students and I walk to the local park
and calculate centripetal acceleration, angular speed and displacement using
merry-go-round. I have found they understand the concepts better when I put
them in the middle of the action.
Safety issues came up again with Mr. DeGennaro recycling aluminum activity.
I try to develop a healthy respect for the dangerous chemicals we use in lab
by doing several demonstrations. For acids and bases I place NaOH and H2SO4
on raw eggs, [ ] H2SO4 in sugar, KClO3(l) and gummy bears and the
flammability of methane. I also model safety during labs and demonstrations.
