The lesson that I taught was about weathering. Then students observed the physical characteristics of a piece of chalk and small container of water. The students then placed the chalk the container. They place the lid on the container and shook the container for a total of four minutes. The students then made an observation of the chalk and water’s physical appearance. We discussed the changes that occurred to the chalk and water. Then they were instructed to answers follow-up questions that related to the activity.The use of my model worked great for me as well as my students. The triumphs of the lesson were that my students were engaged during the lesson and made a connection to how models assist scientists learn about the world around them. The challenge of the lesson was that students were not able to answer all of the follow-up questions with out assistance. Students had a difficult time explaining how the model was similar and different to the actual process. I know with more exposure to models, my students will eventually be able to explain the similarities and differences between models and what they represent.
