What a fun lab! Five great interests approaches were presented this go around. Overall, I felt even more comfortable teaching during this lab after the first teaching lab last week. I presented my interest approach for my lesson titled, "What are the causes of air pollution?" I started with a clear jar of water representing clean air. I handed each student a 'compound' that pollutes the air, such as carbon monoxide or particulate matter. After debriefing the students about not eating the hot cocoa mix or dropping food coloring on their clothes, I began telling a fictional story of my week and having the students come up to the front and add a pinch or a drop of their 'compound' as I told them that I drove my car, mowed the grass, painted my nails, and so forth. The jar of clean water turned into a nice, gross dark green color, and I asked the students that if we could see what is in our air, like how we can see the water in the jar, would we want to be breathing this air? No! Then I made a connection to the objectives.

As far as presentation, I felt more confident; however, the trouble students got me a little flustered again, and I tripped over some words or didn't say certain things as clearly as I would have liked. I think the key here is just practice! Good thing we have almost a whole semester of lab left!
Overall, I'm excited to use some of the ideas that my lab classmates gave me and also watch some of the videos from the other lab session earlier in the day.
