Air and volume...the effects!

The Driving Question for our unit is "How Can I Smell From a Distance?"  As we dig deeper into this phenomenon, it's important we understand some concepts regarding matter.  

Last week, our focus was on determining whether air has mass.  Now we want to see whether air has volume.  But what is volume?  How can we measure it with less abstract things like liquids and solids?

Students calculated the volume of various liquids and solids using three different tests.  Based on the shape of the solid, students either used a length x width x height test, or a water displacement test.  For liquids, students used a graduated cylinder.  

We then extended our thinking into air.  Does air have volume and take up space?

Sorry it's sideways...but you get the drift!
