Everyone has had the experience where you walk into someone's kitchen and you automatically know what they're making. Or you're driving down the road, and you can imagine the type of restaurant coming up on the block! Recognizing these odors is a phenomenon--and how do these odors travel from their source to our noses so that we can indeed recognize them? We've kicked off a new chemistry unit, focusing on the Driving Question, "How Can I Smell Things From a Distance?"
Here are some students' initial models explaining how we smell an odor. Does each model have the following criteria:
1. A nose?
2. An odor?
3. Air?
4. Movement of the odor to the nose?
As models develop and change over time as new evidence is gathered, our initial models create a starting point in explaining a phenomenon. As we gather more evidence, we'll see how our models develop over time....so don't forget to check back soon!
