Week of January 27th-Febuary 1st, 2008
Hello Team 3ers!
Welcome to the “Team 3 Science” blog site. In an effort to integrate technology into the classroom, I have created a blog specifically for our class. This is the first of many posts I will write to you. You can plan on seeing a post from me at least once a week. I will use our classes’ blog to fill you in on what we will be doing in class each week. I will also post the weekly homework assignments. As time passes, my hope is that we will be able to use our blog as a discussion board. So let us get started.
On Friday, most of you began the task of making a fountain. We will continue to work on this for the next few days. You can be sure that at times you may get frustrated with the task at hand. This is not a race or a competition. Everyone has good ideas. Part of this process is taking the time to investigate what will happen when attempting to create various fountain systems. When a group is explaining how their fountain works, take advantage of that time to see what they have created. You may just learn something from your classmates.
Later in the week, we will begin to take a look at the movement of fluids. What are fluids? How do fluids act under various conditions? How is the fountain influenced by the movement of fluids?
Assignments for this week
I would like you to comment on the following questions. You may comment either on this page or in your notebook.
- Describe, in detail, how the fountain works.
- Why is the water moving?
- Can you think of any applications for this concept?
- What were the challenges of this assignment? Were you able to overcome them?

I like this blog is cool because we can like talk. The fountain works because of gravity and prusure.
January 31st, 2008 at 5:52 am
The pressure in the flask, from sucking out the air, creates pressure on the water inside the cylinder, inside the flask. One challenge I faced was figuring out how to do all the requirements for the fountain. But we eventually came up with some smarter ways of going about it!
January 31st, 2008 at 5:54 am
When the syringe pulls the air out of the flask it takes pressure off of the cylender at the bottom. As the pressure gets less and less the water in the cylender goes up and slowly over flows, creating a fountain.
The water is moving because pressure is being taken off of it.
When you put dishes into a sink full of water the water rises.
The challenges of this assignment were trying to create a fountain without breaking a rule. Every time a fountain was made a new rule was created. At the very end it was hard to figure out how to use all the pieces and get all the rules to apply. Int he end my group wasnt the first to create the right fountain but we understood how the fountain worked and why all those rules were needed.
January 31st, 2008 at 5:55 am
1. In the flask you have a cylinder with a stopper on it. Then a big stopper at the top of flask with a rubber and clamp to stop air from getting in and out. Connected to the rubber is a syringe pushed all the way in no air is in it.
2. The water is moving out of the cylinder and pouring into the flask because when you unclamp the rubber and pull the plunger out you are sucking the air out of the flask making the water move and want to get sucked out too.
3. I think this concept is like when you suck on a straw and the water comes up. When you drink all the water you are sucking mostly air but the little drops in the side start to move toward where the sucking is.
4. The challenge i mainly had with this project was thinking of ways to make the fountain. After one new rule was made your fountain you had in the process was pretty much done. You either didn’t follow the new rule or you didn’ t have anything that was going in any direction. When thomas and i got close to having the fountain and the rule of not having it upside down we were stumped! until we figured out that sucking the air out would work but we had no idea how.
January 31st, 2008 at 5:56 am
1. The pressure of the air getting pulled out of the flask also pulls the water out of the cylinder. The small stopper with the eyedropper on it allows the water to come out in a funnel motion when the water is pulled out.
2. The water is moving because the air getting pulled out of the flask is also pulling the water out the eyedropper through the small stopper. It is such a small opening in the eyedropper that the water gets pulled out in a funnel motion.
3. When you pull the air out of the flask, it is also taking air out of the small plastic cylinder, causing the water level to rise. The water has no where else to go so it shoots out of the small stopper and into the flask.
4. We tried many ideas on how to make a fountain work using all of the pieces we were given. My group was very close to the correct idea but we were pulling the air out of the flask instead. We weren’t the first group to complete this assignment but we fully understand how it works and why.
January 31st, 2008 at 5:56 am
1. You use the syringe and pull up forcing air to come out of the flask. When you do that water squirts out of the stopper that in connected to the plastic cylinder that is filled half way up with water, making a fountain that fallows all of the rules.
2.Because when you pull the syringe it is bringing air out of the Erlenmeyer Flask forcing the air from the plastic cylinder out also, making the water rise and making it squirt out of the stopper.
3. When you use a plunger, you first push down then pull up, making what ever you are moving to rise up and get free.
4.There were may challenges when we did this lab.First you just had your standard rules, but it was hard making a fountain jsut using the lab gear. Then every time somebody came up with a fountain you made up a new rule, forcing us to think about how you would make a fountain that fallowed the new rule.
January 31st, 2008 at 6:00 am
When you pull out the syring, the air is pulled from within the flask and from the cylinder. The air that is in the flask and cylinder are pulled up into the syring. The water goes up and spills into the flask. When your in the ocean and your underneath the surface blowing, the bubles you make go up becuase you are blowing the water up. I guess that kind of is related. There weren’t many problems other than the rules were changed every couple minutes so some ideas were thrown out because of that. My group was able to overcome them.
January 31st, 2008 at 6:01 am
The key thing to this fountain is air pressure. By having a cylinder at the bottom of your flask with a little water in it and the rest filled up with air it causes the water to take the space of the air in the cylinder when you suck the air out with a syringe.
The water is moving because while you are sucking out the air your also sucking out the air that is in the cylinder. When you suck that air out too that causes the water to rise and take the airs space.
Well the only real hard thing to this lad was the fact that you kept changing the rules. But than again we also had to think out side of the box in order to have the right fountain.
January 31st, 2008 at 6:02 am
The fountain works by the air being sucked out of the plastic cylinder witch is in the flask. The water is moving because the air is being sucked out of the cylinder so the water takes the place of the air. This assignment was hard because the rules of it kept changing witch made the assignment much more difficult. I’m not really sure of the aplacations.
January 31st, 2008 at 6:02 am
The fountain works by using air pressure. By having the cylinder halfway filled with water, the air that is getting sucked up pressures the water to rise. The water has to fill up the places where the air is leaving so it overflows the cylinder and pours out into the flask.
The applications for this concept was air pressure because you had to take the air and which caused the water to rise.
Why is the water moving?
The water is moving from the air pressure. It took the air’s place by rising.
The challenges of this assignment were understanding what had to be done. I figured that there had to be pressure from sucking out air but I just didn’t know how to resolve it. Finally we overcame it by realizing that it didnt matter if we sucked out air from both the cylinder and the flask, it still meant that the water had to take it’s place.
January 31st, 2008 at 6:37 am
1. We used the syringe to pull out the air in the flask. this makes the water draw out of the small beaker thing.
2. there is less pressure in the flask to push down the water, so now the water can rise because there is less pressure.
3. Barometer’s detect the pressure in the air which if you know how to use it you can read whether it is going to rain or be sunny.
4. It was difficult that you kept on changing the rules to make the fountain.
January 31st, 2008 at 6:38 am
this fountain works because when you pull the syringe up it draws the water out of the cylinder because there is no other air in the flask. The challenges of this assignment were that ms. TBO could change the rules at any time but that also kind of helps because that steers you in the right direction
January 31st, 2008 at 6:39 am
1) The way the fountain works is that when you suck the air out of the flask it sucks the water out of the tube and that makes a fountain.
2) The water is moving up because of the amount of pressure that is building up from when you suck the air out of the flask.
3) One is when you put a cup over your mouth and you suck the air from it. It takes the air out of it and it builds up pressure but the only thing about it that is not the same is that you don’t have water coming out of your mouth.
4)The Challenges of this assignment were trying to figure out how to make it and i overcame them by trying to use an idea that came into my head.
January 31st, 2008 at 6:40 am
1) how my fountian works when you suck the air out of the flask the water in the little container with the black top on it pushes the air out of itand into the flask and then pooors out the sides
2) the water is moving because the presser in the flask is building up ansd over flowing
3) the fire hidrins that fire fighters use when that is open ther is so much water built up in it that whe open it is released
4) the rules for making the fpuntian were
1 no glass on glass
2 only one tube
3 and the water must go up
4 and the has no water in the schring
January 31st, 2008 at 6:41 am
1. When the air is taken out of the flask by the syringe the water inside the small beaker is forced to com out of the big stopper.
2. the water is moving because there is no more air so the water is pulled out.
3. to move water like a fountain does it is usally man made for example irragation is a way to make a fountain because you have to use tools to make the water go from one place to another.
4. Some challenges in this assinment were the frustration of the rules constanly changing and i was not able to overcome this becuase i did not figure it out.
January 31st, 2008 at 6:41 am
1) The fountain works by pressure. When you fill up the vile half way with water. I sucked all of the air out of the flask with the syringe. When there is no more air you will start sucking up water up through the vile till it pours out of the vial. Then you have a fountain.
2)The water is moving because there is nothing left to suck out so it starts sucking out the water till it gets out of the vial and falls to the bottom of the flask.
3)One thing is when you have a little water in a cup and you put your mouth in it so no air can get out and suck in. The air compresses and the water move a little. Another is the vacuum cleaner. When you put that on your mouth it sucks the saliva out of your mouth and into the vacuum. Those are only two I could think of.
4)Some challenges were working with all the rules Ms. Tbo thought of. Then just figuring out how to get it to work. Then getting the right amount of watre in it. Those were the hardest problems.
January 31st, 2008 at 6:42 am
1. My fountain works by the pressure. The vile is filled up about half way with water and its in the flask. Then you take the syringe and take out all of the air from inside of the flask using the clamp and the stopper. You take out the air between 2-4 times. by doing that it will have sucked up the water out of the vile and a little fountain will appear.
2. The water is moving because when you take the air out of the flask and leave the stopper on it with the clamp closed and then you open it, it sucks out the water from the vile, making it turn into a little fountain.
3. Some thing like the fountain is when you have a drink, and you use a straw to drink it with. Your putting your mouth over the straw and that causes no air to come in or out so when you suck on the straw the air goes up.
4. I thought this assignment was kind if hard for me. In my group i worked with Matt2 and Ryan2. We took a very long time thinking of ideas. After we thought of some then the rules were changed so we had to change our ideas. We tried so many things but it just took forever. Finally at the end somebody helped us make our fountain work. Matt2 and I were very close to getting it only we were wrong by like two things!
January 31st, 2008 at 6:42 am
my fountian works by having the seringe thing push air down threw the rubber tube then by having the rubber tube conected to the cork thing.the air would be putting presser on the small plastic thing making it explode into the flask.
January 31st, 2008 at 6:43 am
1.The fountain worked because you had just the right amount of water in the little vial and by taking air out of the beaker you take the water with the air which makes the fountain.
2.The water moves because the pressure is building and the water has to escape so it just escapes out the glass and into the beaker.
3.I think Volcanoes work this way because the pressure builds up and the magma escapes out of the tip of the volcano and onto the ground.
4.One challenge was that ms tbo kept changing all the rules we overcame this by just letting her change the rules to the only solution that she liked.
January 31st, 2008 at 6:44 am
1) Our fountain works by taking air out of the flask and eventually taking the water out of the small cylinder with water in it.
2) The water is moving because all the air in the flask has been sucked out and now since the only thing left in the flask is the water in the small cylinder thats what comes out.
3) I guess breathing obviously works like this experiment. You breath in and out but it’s not exactly the same but. I don’t think volcanoes work like this but they might. Nothing else really applys so thats it.
4) The challenge is that Tbo kept on changing the rules such as:
1. No water in the flask, no water in the syringe.
2. Use one of everything.
3. Water must be moving up.
4. Water must be contained.
5. Cylinder must be in the flask.
6. No glass on glass.
7. Tbo can change or make more rules.
So once we overcame all of these rules we finally did what she wanted us to do. That was the challenge…….rules the things we teens don’t like.
January 31st, 2008 at 6:44 am
1) The air is taken from the flask, and in conclusion, the air is sucked out of the little vile inside it. When all the air is out of the little vile, all there is left is water. Since there is no air in the flask, it’s pulling the water out from the vile with the glass tube, and pouring it into the airless flask.
2) Air pressure in the vile is pushing it out as air is pulled from the flask. As the air pushes the water out, it overflows out of the vile, into the flask, creating a fountain.
3) Volcanoes built pressure, and that’s why they erupt. The air is pulled out, leaving only magma to come out.
4) The challenges were finding a fountain design, and having her create new rules that make your design wrong. It was pretty frustrating, but after a while, some good ideas came out, and after her final rule, “the vile must be in the flask,” a team got in within minutes.
January 31st, 2008 at 6:44 am
1 The air in the little vile is deceasing so it brings the water up too.
2 The water is moving because the air is pulling it up .
3 it is like a park fountain.
4 to make a water fountain it was vary vary hard to over come the challenges.
January 31st, 2008 at 6:45 am
1 The air in the cylinder is decreasing as it fills up with water so when the syringe is is being pulled, it has nothing else to push up, except for water.
2 The air is pulling the water up.
3 It is like a water fountain.
4 The challenges were the teacher changing the rules a lot. I was able to overcome this by thinking of new ways of making a fountain.
January 31st, 2008 at 8:07 am
the fountain works by putting water in the viell only haft way then put it in the flask then put the cork on top of the flask then suck the water out
January 31st, 2008 at 8:10 am
1. when you suck the air out of the flask it also tries to pull the air out of the vile thing and it takes the water along for the ride.
3. a motor work the same way when the piston goes down the suction pulls the valve open and pulls the air and the gas in to the cylinder.
4. the challenges were only being able to use one of every thing and the water had to be the contained.
January 31st, 2008 at 8:12 am
1.The fountain that Scott and i figured out how to work was so cool like when you suck out the air how the water comes out of the smaller plastic beaker came out.
2. i think that the most challenging thing with this lab was the amount of aggravation that i had on trying to find new ways to make this work i figured this out though
January 31st, 2008 at 8:14 am
The fountain works by when you take the air out of the beaker and then the water will come out of the little plastic bottol and that is the fountain.
The water is moving because you are taking the air out of the beaker the water has no were to go.
January 31st, 2008 at 11:48 am
Challenges of this asignment
Q4. The main challenge was that you were always able to change the rules on us. The way that we overcame this was by listing closely to your new rule and trying to alter our fountain design to match the new rules. The other challenge was to using the limited equipment that we had and making what we thought was a fountain. To tell the truth in the beginning i had invisioned the fountain looking very much different than the finished product.
January 31st, 2008 at 2:30 pm
The Final Fountain
1.You put a cylinder with just the right amount of water and the small rubber stopper in an Erlenmeyer flask. You then put a rubber stopper on the top of the flask with a rubber tube attached to it and a clamp on the tube. You now attach a syringe to the rubber tube, unclamp the clamp, and start sucking out air. When you sick out the air it pulls the water through the stopper and out the cylinder.
2.The water is moving because the air being sucked out pulls the water upwards.
3.I can’t really think of any useful applications for this concept.
4.Some of the challenges my group had were for one abiding by all of the rules, and also not making a mess. How we overcame these challenges were by creating a self contained fountain which abided the rules ( aka. the final fountain.)
January 31st, 2008 at 2:42 pm
1) you take a glass vile and you put in a little container with half water half air and with the smaller of the two rubber stoppers cork it. then cork the vile with the larger of the two rubber stoppers. add the rubber tube to the rubber stopper and then add the suringe
and push down on the suringe which will cause the air in the little container to push up th water will go with it and their is your fountain
2) the air from the suringe + the air in the little container = water forced up
3) a volcano because the lave(water) is pushing out of the mountain with the help of air
4) I think the main challenge was that we had to think of ideas wile you kept changing the rules and in the end yes I think we over came the challenge
February 1st, 2008 at 5:39 am
Make a Fountain
1:First, you take a cylinder, put a small stopper in the top and drop it in the flask, so it lines up with the opening in the flask. Then, you put a big stopper in the flask. Then the tube with a clamp in the middle goes on the stopper, and a syringe goes on the end of the tube. Then, you open the clamp and use the syringe to pull air out, and some water comes out of the cylinder through the small stopper.
2:The water moves because the pressure in the tube pulls the air from inside the flask into the syringe, and there is air in the cylinder with the water, so it draws up the water too.
3:It’s kind of like a plunger how it pulls the water up, then the water goes back down.
4:It was hard to come up with an idea around all of the rules we had. We finally learned how to do it when another group found it.
February 1st, 2008 at 5:39 am
How the Fountain works,when the cylinder is sitting in the bottom of the flask with water in it and you connect the rubber tube to the stopper and take the air out, and then pressure decreases and the water rises because the syringe is taking the air out of the cylinder and the water is trying to take its place.
Why is the Water moving?, The water is moving because we connected the rubber tube to the stopper, and there is a cylinder sitting on the bottom of the flask. So what we did was connected the syringe to the other end of the rubber tube and took air out and that decreased the pressure building up in the cylinder so when we took the air out the water was starting to take the airs place.
Any applications?,
Challenges, My group had a few challenges when we tryed to make this fountain, our first fountain we just took a syringe and put water in it and pressed it down and it came squirting out.
But we finally got the right fountain. :]
February 1st, 2008 at 5:44 am
Think of Applications
Q3. I can think of no useful ways to use this product. the only thing i could do with this is set it up and watch it work. it might make a cool rocket though, all you have to do is fill the cylinder with vinegar and line the bottom with baking soda do the same thing and presto the flask will explode.
February 1st, 2008 at 5:45 am

February 1st, 2008 at 5:50 am
The fountin works because you creat a vacume inside the flask. That sucks the water out of the plastic cylinder and creats a fountin. When you pull the syringe it makes a vacume and caues the water to be sucked in to the flask making the water move. This same consept is used not only on fountains but on anything that has a water pump, Such as a sink. The bigest problem we had to overcome was getting the water to shoot up and not down. We did this by useing a small platsic cylinder inside the flask. That sucked the water out of it because of the vacume we created by sucking the air out with the syringe.
February 1st, 2008 at 7:10 am
i thought the fountain lab was very interesting.
February 1st, 2008 at 7:15 am
(1) You suck out the air from the flask. When you suck it out the cylinder filled with water will start to come out. That is how you get the fountain to work.
(2) Because the force is making it come out because there is no air to stop it from coming out.
(3) A sink and a fountain are the by both of them each have water coming out.
(4) trying to make the right fountain. yea we over came it.
February 1st, 2008 at 7:15 am
1. You suck out all the air and the water comes up.
2. Because the air forses the water up.
3. What does applications mean?
4. The chalenging part was ms tbo kept macking up rules as we went. No we didnt overcome untill someone showed us.
February 1st, 2008 at 7:16 am
1. it depends on which kind but it shoots out water through a spout
2. pressure a syringe
3. a fire hyderant
4. ms.t changing the rules. and yes i did overcame them.
February 1st, 2008 at 7:17 am
The fountain works because all the air around the plastic cylinder is being sucked out of the flask by a syringe and it forces the water out of the plastic cylinder though the glass tube and it creats a fountain.
The water moves out because there is air in the plastic cylinder and it gets sucked out then the water gets foursed out.
Some thing that would work like the fountain works worl be a cuo and a straw. Since the air is being sucked out of the straw the liquid is fourced up.
The hardest part of this lab was working with all the rules so the fountain did not make a mess. My group just worked around the rules. Soon we got really close and then one of the people finally figured it out.
February 1st, 2008 at 7:18 am
1.The fountian works, when you fill the little cup with water in the glass cylinder then you put the black stopper on the top and put the tup on top of that then you take the surenge and pull up, and eventually the water will come up.
2.The water is mooving because you are sucking it up with the surenge.
3.A garden hose.
4.The most challenging part of this was finding out what would make a fountian and what to use for the fountian, yeah we were kind of able to overcome them.
February 1st, 2008 at 7:20 am
#1/#2 The fountain works because while the air is sucked out of the flask all the air around the cylinder is being sucked out so the water in the cylinder is being sucked up and is forced to come out.
#3 the sinks in the room a shower, hot tubs, water slides, straws, and others too.
#4 the assignment wasn’t too hard because if you thought about it, it wasn’t to hard to come with different idias untill Ms.tbo made different rules the it got tricky.
February 1st, 2008 at 7:24 am
1. First you fill up the cup w/ water. then you place the cup into the flask put the rubber stopper on top of the flask so no air can release. place a rubber tube on the glass of the rubber stopper and clamp the rubber tube. then get a syringe and start taking the remaining air.
2. The H2O is forced out of the mini flask from decrease of air pressure in the flask as you suck it rises higher and higher and eventually its spills out of the cup.
3. a hose. the tube is the rubber tube. the clamp is the head. the flask tank that holds the water. the water in the cup is the water in the tank and the pressure for the water to come up is the syringe.
4. The only challenge in this lab was that you had to use all of the equipment to make it work. also it was difficult how Ms.T-bo should add rules @ any time she wanted.
-that was fun!
YA
February 1st, 2008 at 7:25 am
First you build it then the fountain.Then it works by you taking all of the air out of the flask. Then by doing that it will force the water to rise out of the cylinder.
A sink because they both have water coming out of them.
The water going everywhere because everyone kept having that happen to them.We over came this by putting less water in the flask and holding the stopper down.
February 1st, 2008 at 7:25 am
the fountin works by putting a little plasitic vile in a flask with a black rubber thing.on the flask you put another black rubber thing and with a rubber tube and hook up a seringe pull the air out and as you pull it out the water slowly comes up.as the air is coming out it pulls up the water. some of the challanges were trying not to get water out of the flask. but we were able to overcome that by bending the rubber tube.
February 1st, 2008 at 7:26 am
the fountain worked because of the decrees of air so it was sucking out the air from the water.
the water was moving because there was no air in the flask and there was air in the water so the no air place was trying to get air.
and thats how it worked.
the challenge was when miss T-Bo said we had to use all the tools and no water in the flask, we thought it was imposible. but soon or later we would figure it out, in this case sooner. thanks miss T Bo.
February 1st, 2008 at 7:27 am
Q#1The fountain works by taking th syringe and sucking the air out of the flask and the water rises out of the cylinder and small stopper
Q#2The air pressure makes the water come out of the small stopper.
Q#3The faucet is just like the fountain in science because the water that comes from the faucet comes from the pipes. In a way they are a like.
Q#4 The challenges of the fountain challenge was that it was really hard to work up to your expectations because we could only use one of every piece. We overcame the challenge when one of the groups found the solution and we had to do the same and draw a diagram of the fountain.
February 1st, 2008 at 7:30 am
1. First you put water in the cylinder (half full) and then put the rubber stopper on the end then put the cylinder in the flask put the another rubber stopper on the flask put tubing on the rubber flask the is on the flask and use the syringe to suck the air out until the water leaves the cylinder,that is your fountain.
2. the fountain works buy pulling the air out of the flask creating presser that pushes the water out of the cylinder ,witch is inside the flask.
3.
4. I think one of the most challenging things were mis T-Bo’s hints they didn’t really help and they just made me more confused also question 3. i didn’t under it meant .
February 1st, 2008 at 7:58 am
The reason why the fountains works is that when you let go of the clamp the air want to go up and it takes the water with it do to the compressed air in the flask and in the mini flask,
The water is moving because the air is trying escape the flask and the mini flak and the water is in the mini flask and in the process it takes the water with it.
A vacume because the vacume pulls air and lets some out to. In the process the air take anything in its way in it like dirt or stuff.
The challenges were that you changed the rules and each time I got of an idea it went against the rules and I couldn’t do it until you told us what to do.I though the fountain would be bigger.
February 3rd, 2008 at 9:12 am
I would like to commend you all on your perseverence in working to make a fountain. I must say, you all had some really good ideas. Many of your fountains were far more exciting than the final fountain. Although the final fountain will help you all begin to understand some new concepts. Many of you already have a good sense of how the fountain works as a system. Why does the water move up? What are the changes that are taking place, when pulling the syringe, that force the water to come up through the vial? I do not intend to give you the answers to these questions quite yet. As we continue to investigate the movement of fluids, my hope is that you will be able to further strengthen your own explanation.

One more question to pick your brains about.
Why doesn’t the fountain work when the plastic cylinder is completely filled with water?
Any thoughts?
