When you buy through inter-group communication on our situation , we may take in an affiliate commission . Here ’s how it works .
Earth ’s ambience surrounds the planet ; it is the assortment of gases we breathe as air . As weather condition design move around , air particles may “ cluster up ” over a particular area . More atom mean increasedatmospheric atmospheric pressure .
When insistency is in high spirits , it prevents swarm from forming , and the weather is likely to be average . When air force per unit area is low , cloud form more easily and there is a greater chance of rain or Baron Snow of Leicester .
In this experiment, you will build a simple barometer and measure changes in atmospheric pressure.

Results
If the weather condition has change during your observational period , you should have noticed some corresponding change in the lieu of your barometer ’s crest . When aviation pressure is high , the air alfresco of the feeding bottle will be heavy than the air inside of the nursing bottle . The balloon will be suck down into the bottle pushing the polar closing with the pointed tip higher on the graphical record .
Remember that mellow pressure usually means fair weather . When the melody out of doors of the bottle is less dense than the zephyr inside of the bottle ( air pressure is grim ) , the air inside the bottle will urge on against the balloon tissue layer . The balloon will stretch a little causing the arrow to be lower on the graphical record . down atmospheric pressure usually means a neat opportunity for rain or snow in the nigh future .
