Today we went over air pressure and why there is LOW pressure, LOW density, and LOW temperatures near the top of the atmosphere, but there is HIGH pressure, HIGH density, and HIGH temperatures where we live. We also completed our air pressure lab as well that you can try at home if you want!
Since we lit a candle, it caused all the oxygen to be used up and just leave nitrogen and carbon dioxide in the glass. These are two gases that are not very dense, which caused them to rise in the glass. When they rise in the glass, it sucks everything else up with it. This includes the water and even the paper plate! You can see that almost all of the water was sucked into the glass and even the paper plate was vacuumed to the jar.
HW: Finish your lab sheet if you have not already done so. Short quiz over air composition and air pressure tomorrow. Unit 5/6 folder is due TOMORROW!!
