      <title>What is air?  by Debbie Pavlowski</title>
      <link>https://padlet.com/dpavlowski/ccoswqrm325l</link>
      <description>1. When you clamp the tube closed and push the plunger down, what happens to the air?

2. Is there more air, less air, or the same amount of air in the syringe when the plunger is pushed down?  How do you know?

3. What happens when you let go of the plunger after pushing it down?  Why do you think this happens?

         <description><![CDATA[<div>1. When I clamped the tube closed and pushed the plunger down I noticed that I couldn't feel a lot of air. 2. I think that there is less air when the plunger is pushed down. 2. I know because when I did push the plunger down there was no more air left in it.  3. When you let go of the plunger after pushing it down you can't feel any air afterwords. 3. I think this happens because after you let go of pushing the plunger down there is going to be no more air because your not putting pressure on it anymore. </div>]]></description>

         <description><![CDATA[<div>1.When I clamp the tube down the air stops and nothing comes out. 2a. There is less air when you push the syringe. 2b. I know this because when you pull the syringe, you suck in all of the air. Then when you push the syringe the air all comes rushing out. So, when it comes out there is no air left in the syringe compared to before. 3a. When you let go of the plunger it pushes/goes back to its normal place instead of staying there. 3b. I think this happens because there is no air for the syringe to suck in or push out.</div>]]></description>

         <description><![CDATA[<div>1.When you clamp the tube closed  and you push the plunger down the <br>air doesn't come out it waits until you open it again. <br>2. But, there is the same amount of air you started with.<br>3. I know because I pulled on the syringe and when pushed on to my patters hand it was the same amount she said. <br>4. I think when after you pull and trap air inside and then let go the air will get out of the syringe. <br>5. I think why the air gets out if you let go is because the air cant just stay in there it hasted to released like when you breathe in air the old air comes out. <br> </div>]]></description>

         <description><![CDATA[<div>1) When you  put your finger on the tube and push the tube down the air is still in it just settled so you start to not to feel it any more, 2-3) but when you take your finger off and push the syringes plunger down all the air goes out, I know this because you can feel it come out and sometimes you can hear it come out, This happens because the plunger pushes all the air out so then there is no more air in the syringe.</div>]]></description>

         <description><![CDATA[<div>1. when  you clamp  the tube togeher it gets stuck or the air is harder to get out. 2. So it takes work to get the air beacause  there is not as much air as there used to beacause the tube is clamped together. 3.I know beacause when you let go the 2 syringes the top of it pushes together and the air goes back in the rubber  tube.4. I think this happens beacuse the air is clomped between the 2 syringes so the air is stuck in the tube while the tube sites in the middle.</div>]]></description>

         <description><![CDATA[<div>1.) When I clamped the tube and I pushed  the plunger down I felt less air.<br>2.) There is less Air when I put the tube on and the air comes slower than with out the tube.<br>3.) I know because the tube gives less air to escape.<br>4.) I Think this happened because it takes longer for the air to get through the tube.So it slows down the air because it takes longer to get through the tube.</div>]]></description>

         <description><![CDATA[<div>1. When you clamp the tube down and push the plunger it is giving out less air. <br>2. If you put a plunger on each side of the tube and one person pushes it from one side and another pulls from the other side it is like a magnet.<br>3. I think that if there is a tube on the plunger it will give out less air because the plunger only gives out a certain amount of air and the tube is long, the air will not force the air hard because the air has to travel. I bet that is why we can't see air or feel it.<br><br><br></div>]]></description>

         <description><![CDATA[<div>1. When you clamp the tube closed and push the plunger down. The air gets trapped inside the syringe.<br>2. When you push the syringe down there is going to be less air in the syringe. I know because when you push the air out how is there going to be the same amount of air.<br>3. It pushes all the air out of the syringe. I think this happens because that black part of the syringe is pushing all the air out.</div>]]></description>

         <description><![CDATA[<div>1.)When i clamped the tube closed and pushed down i did not feel air but i felt resistance. <br>2.)There was the same amount of air.I know this because i looked at how full it was and it stayed the same.<br>3.) The tube pushed back too full. I think this happened because there was space in the tube but  when I released pressure  it flows back in the tube.</div>]]></description>

         <description><![CDATA[<div>1) When you clamp the tube and push the plunger down you pressurize the air because there is no place for the air to go and all it can do is compress apon itself. <br>2) When you push the plunger down there is less air in the syringe because the air is being pushed out. <br>3)When you let go of the plunger when you are pushing it down is that it comes back up a little because the hole on the syringe is so small compared to the amount of air getting pushed out so it makes pressure and you don't apply any more force pushing down on the  plunger the easiest to stop the air pressure is to push it back up.</div>]]></description>

         <description><![CDATA[<div>1. When you clamp the tube closed and push the plunger down the air gets stuck and will slip out of the tiny cracks the air makes well you push the syringe top down. 2. there is less air that comes from the syringe.3. I know that because the air that's being pushed down has nowhere to go so there's less of it.4. When you let go of the lever after pushing down there will no longer be any air in the tube. 5. I know this because after you push the top of the syringe down the air gets  emptied from the syringe.</div>]]></description>

         <description><![CDATA[<div>1.When you clamp the tube closed and push the plunger down the air get's lighter, it feels soft. 2.There is less air in the syringe when the plunger is pushed down. I know because the air feels like there is less. 3. When you let the plunger go after pushing it down it get's foggy. this happens because the air is trapped and the air expands so it makes condensation on the sides. </div>]]></description>

         <description><![CDATA[<div>1. The air gets trapped because the clamp closes the "door" and the air get trapped. <br>2. When the plunger is pushed down some of the air leaves and I know this because if it's not got a "closed door" and you push out the air escapes <br>3. When you push it down and let go nothing will happen I know this because there is know air pressure  if there is know air.</div>]]></description>

         <description><![CDATA[<div>1.) When I clamp the tube closed and push the plunger down no air comes out because i'm covering it so it stays in the tube.<br>2 a.)  There is the same amount of air in the syringe but barely any or none comes out.<br>2 b.) I know this because i only feel little air but i know that the air can't just disappear.<br>3 a.) The plunger goes up more and doesn't stay in the same place and some air comes out of the tube.<br>3 b.) I believe this happens because the air is still in the tube and its been stopped for awhile.</div>]]></description>

         <description><![CDATA[<div>1. When you clamp the tube closed and push the plunger down, their is less air. Their may be no air if it is all the way closed.2. I know because I did this experiment myself. 3.When you let go, more air will be sucked in than the tube being closed.4. I think this happens because the syringe sucks in air, but, if the only open area gets closed, their is no other area the syringe  can suck in air, so no air can come in.</div>]]></description>

         <description><![CDATA[<div>1.-When you push the plunger down, it pushes the air out and it is harder to push the plunger down. The reason for this is because there is so much air in the tube, it has such a small tube for the air to get out. When the air is in the tube, and the plunger is pushed down, the air is in the tube and released at the other end if there is not another plunger at the other end.<br><br>2.-There is less air because when you push down the syringe, you press the air down to the exit tube. You suck in the air when you pull it up.<br><br>3.-When you let go of it, it would go back in because there is no air in the tube, or in the other syringe. </div>]]></description>

When you let go of the plunger after pushing it down it would  go back down on its own. Also I think that happens because     the air goes back in instead of going forward.</div>]]></description>

         <description><![CDATA[<div>1. When I clamped the tube down and pushed the plunger down the air had know where to go so it was hard to push the plunger down and no air came out.<br><br>2. When the plunger is pushed down there is less air then when the plunger is pulled up. I know this because I could feel the air coming out.<br><br>3.  When I pushed down the plunger when they where connected the plunger shot back up. I think this happens because the air is trapped in the tube and when you push the plunger down there is to much air pressure so when it is no longer being pushed the air pressure releases and it makes the tube shoot back up. <br> <br><br><br></div>]]></description>
