We're starting to think even more about air, especially now that we know how changing volume and mass affect what air looks like and what it is able to do. We're also starting to think about how air impacts what we can smell along with how it affects the time it takes to smell something.
A simple demonstrate with adding air to a flask allowed students to see how having an odor, along with air, could possible affect one's ability to smell an odor. Some new questions that surfaced were:
1. Since air takes up space and has mass, we're wondering how odor is in the air. Like, does something have to melt and then evaporate in order to smell it?
2. But not everything melts or gets heated up when we smell it. Does a solid evaporate? We smell solids, but we certainly don't think that they're melting and evaporating so quickly we can't see that. Does air play a role in this?
3. We're still stuck on why we smell some things more so than others. Does air play a role in that? Or is it something about the odor? Do odors have different strengths? If so, why?
