In the past few weeks, we learned about the periodic table, atoms, Bohr diagrams, Lewis structures, and bonding. The kids are really comfortable with using the periodic table and we’ve been having fun with it. Below is a list of teacher lead activities that we completed. We also enjoyed the Periodic Videos from our friends in England!
Today we set up and started our stations lab for building molecular models. I don’t have enough models for everyone to have their own set, so I broke it down and set up stations for the kids to build them. I also added some “make your own” for those pairs of students who are waiting for one of the other stations.
The kids will rotate through the stations making 3-4 molecules per station. For the Lewis Structures, I have the students try it, if not, they just draw the Lewis Structure for the individual atoms. For a 5th grader, drawing a Lewis structure for more than 2 atoms bonded together is a tough concept.
Below are some pics of how I set up the stations. I am using large 4×6 colored index cards for the stations. Glucose is a challenge station, each year I have one or two groups figure it out with only one or two clues from me. I don’t tell them its a ring structure, my clue is that it’s not a straight chain.
