Today we learned about the layers of the Atmosphere. We made a model of the layers using aquarium rocks and recycled glass bottles along with some labels I found that worked well. The pictures I used to label our bottles are from http://www.theozonehole.com/atmosphere.htm. I attached the label with mod podge and then some of us glued/packing taped the larger label to the side and others used rubber bands after hole punching. Both worked well and it was just a matter of personal preference.
