[Channel-talkchemistry] Reactions in chemistry, workshop 1 atoms and molecules post

I would like to post my comments related to workshop 1 atoms and molecules.
For me the focus of this film and discussion is based on models used to
explain, reinforce and develop atomic theory. I start this unit (which
covers 3 chapters) with students drawing their idea of an aluminum atom.
This helps me to see where they are at and then at the end of this unit have
them redraw the same model see how far they have come. Some of the models I
use are an atomic class ( string, tape and crepe paper strung through out my
room to represent the X, Y and Z axis, s and p orbitals),quantum land
activity ( list of rules similar to rules for electron configuration to
place ≥ people≤ in atomic villages), balloons (6) attached to represent the
three p orbital and balloons attached to represent the various molecular
shapes. In addition I use the world of chemistry film series on the atom
and periodic table, a periodic puzzle activity similar to Mr. Williams
periodic table activity presented in the video and a lab making molecule
models with tooth picks and styrofoam balls similar to activity presented in
the video with balloons. I will save my response to the each segment of the
video and homework for my next post. I look forward to hearing you
response. Joe Lannan
