The following experiments give us a good look of how air pressure works. Please watch the video's again, and share your thoughts about what you understand about air pressure.
This are some of the things that I know about Air Pressure: * Air pressure is very strong * the lower you go, the thicker air molecules are and the higher you go, the thinner air molecules are *Air contracts when cold, and expands when warm *we would be crushed by air pressure, if our bodies didn't resist the air pressure to balance it out *barometers are used to measure air pressure
Air Pressure Here are some of the things I know about air pressure: *Air pressure is very strong *Air pressure is stronger at sea level because the air molecules are compacted *Air pressure is not very strong at mountain height because there are fewer air molecules and they are less compact * Air pressure can keep items (such as a paper towel) from getting wet
Air pressure We learned air pressure is strong and can suck thing's in.We did an experiment where a boy took a napkin lit it on fire the put it in a jar.he then put a balloon on the lid of the jar and watched it get sucked in.Air has greater on the ground and less pressure up high.AIR IS DENSE!
I learned that air pressure is strong, strong enough to crush us! if we didn't have air pressure pushing out of us, air would crush us. We also saw a lot of experiments showing how strong air pressure is, like the Iron Finger experiment, and the balloon jar experiment. Also, the higher up you go, air pressure isn't as packed, and the lower down you go, the more packed the air pressure is. The higher you go up, the hard it is to breath. I also learned that air expands when it's warm, and contracts when it's cold. And usually when there is low pressure, it means that there is going to be bad weather, and when there is high pressure it usually means there is going to be good weather.
Barometers are used to measure air pressure The higher you get there is less molecules and less air pressure and the air is less dense. At sea level the air pressure has more molecules. Air pressure expand's when it is warm and contracts when it is cold. We would be crushed by air pressure if our bodies didn't resist the air pressure so earth is all calm and balanced out.
I learned from air pressure is that air pressure is all around us which is pushing at us but we have air pressure that is coming out of us so we don't get crushed by the air. Therefore the lower you go the more molecules there are and the higher you go the less air pressure there is. you can't feel air pressure unless you go in a airplane which there is a sudden drop in the air pressure. That is what I learned from air pressure.
I learned that air pressure is very strong. Air pressure can lift things like a stool (as showed in iron finger vid). It can resist a student, even horses tugs. Air pressure is similar to water pressure. The lower you go in water the greater the pressure. That is the same with air. The higher you go the less dense air is so that means the air pressure is less. The lower you go the more dense the air is so that means the air pressure is greater. You can also determine weather with air pressure. The lower the air pressure that means bad weather. The higher the air pressure that means there will be good weather.
What I Know About Air Pressure! I know that if there is less air pressure it is colder because the molecules are more spaced out and, because the air can move farther out. This is instead of when there is more air pressure the molecules are packed which creates friction happens. Also I know that if we didn't have air pressure exiting our bodies the air pressure in our atmosphere could crush us alone.
While doing or watching the experiments above, I learned a lot about air pressure. Air pressure is really a very simple thing after you start to understand it. First I'm going to start with how air pressure affects weather, this is a very simple topic because there is very little to it. The weather is basically caused by how much pressure is in the air, for example, when there is high pressure that means there will be nice weather and when the pressure is low that means that there will be storms and cold weather. Coming to an end of weather brings me to my next topic, how hot and cold affect air. The hot and cold affect the air pressure because when it is warm the air will expand and when it is cold it will contract. That is just a bit about air pressure and I'm hoping to post more
I learned that air pressure is all around us, but the lower down you go the more air molecules are packed, creating greater air pressure. However if you go higher, like the mountains, the air molecules are less packed and more separated. Scientists can measure the air pressure by using a barometer. They can also use these results to predict what the weather is going to be like. When air pressure is low it usually means bad weather and precipitation. When there is high are pressure it usually means good weather and clear skies. I also learned that the only reason air pressure around us isn't crushing us is because we are also pushing air pressure outside of us. In one of few experiments that we did I learned is that air will contract when cold and expand when heated. I have learned a lot so far, but I hope to learn even more!
Air pressure is related to how close together the air molecules are. The closer the air is to sea level, the denser the air. People measure air pressure using a barometer. Low air pressure usually means bad weather. Air pressure also held the paper in position, because the pressure was sucking the paper back. This is suction. Air will also contract when it gets cold and expand when it's hot.
That the closer you are to see level the more air molecules there are which means more air pressure. The higher altitude you are the lower the air pressure. Air pressure would crush us if we didn't exert pressure. Air also expands when heated and shrinks when cold.
