5: Gases
Vacuum Candle Experiment
This Journey was all about branching off of the Forces Journey to a more specfic topic; Gases. We learned a lot about how Gases affect solids and liquids by controlling experiments where we could see physically how much they changed some outcomes. It's harder to notice their affects because Gases are usually transparent. My favorite lab from this Journey was when Ramsey crushed the Yerba-Mate Can (sorry Kheva). It was impressive to see how much pressure is really exerting on objects without them knowing. I remember Ramsey pointing out, after the can had been crushed, this is the amount of pressure that is being exerted on all of our heads all the time. I was amazed and scared, even though I had already learned that our bodies are withstanding this sort of pressure all the time. I just had never seen it physically. Learning how to calculate PV=nRT equations (Ideal Gas Calculations) was fairly easy, and I can't wait to refuse to solve a PV=nRT question because the test maker gave me an element that's not an ideal gas. (They can't trick me now). I actually do not have a question for this Journey, and overall I thought this section was extremely interesting because I don't have a lot of experience working with Gases, since at my middle school they focused on just solids and liquids.
