Recognizing that gases can transform to solids (as with the menthol gas) and to liquids (as with the water vapor), we're digging deeper into better understanding what gases can do. How can understanding what gases can do help us to better understand why we may smell an odor?
In a simple demonstration with a closed flask and air pump, students are developing models to explain what air looks like when it is in a closed container, what happens when air is removed from the container, and what happens when air is added to the container. Our understanding is not clear yet...and this is okay! We're working towards an eventual consensus model that explains everything that gases can do and how this relates back to our driving question.
