Mrs. White had a thin, solid piece of material. She placed the material in water and it floated. She took the material out and punched holes all the way through it. What do you think Mrs. White observed when she put the material with holes back in the water?
A: It will sink.
B. It will barely float.
C. It will float the same as it did before the holes were punched in it.
D. It will neither sink nor float. It will bob up and down in the water.
Explain your thinking. What "rule"or reasoning did you use to select your answer?

I think A: it will sink because the wholes will prevent it from floating
ReplyDeleteI dissigre
DeleteI agree with Arshee because water will come in the holes
DeleteB it will barrle flot becsuse the little meterial taken off it will take less time for it to flot
ReplyDeleteI think it is A Melanie,because before it had holes ,it floated because it had materials of air and THAT ,air is what makes it float but now that it has holes there is no more air so it will sink.
DeleteI agree with Franco because also the water will come through the holes.
DeleteI agree with Franco. The water will come up through the holes and eventully get on top of the material. The weight of the water will be too much weight for the material to hold up, so it will sink.
DeleteI agree with Aidan W. because when there were no holes air got trapped underneath it. But when there are no holes air will leak out from under those holes causing it to sink.
DeleteI think it's A too because all the water will go on top of the solid because of the holes. Later it will sink.
DeleteI agree with Eathan the hole will let water and when there is water it will pull it down

DeleteI agree that the material could be less likely to float if it were something like paper but it doesn't say. If it were plastic it would float with holes. If I had to pick I would say A because holes would let water come up. It would make the material heavier.
DeleteI think it is B because the material will start to fill up with water, but it won't be enough water to sink the material completely. Just like the spoon did when we were testing which floats or sinks, the spoon started filling up with water and finally sunk to the bottom just as I predicted.
ReplyDeleteI agree
Deletethe paper has a great bouyancy
so after she punched holes in it it wont sink..
but barley float I thik its like the spoon too.
Except I thought because it was light in weight it would float
but then I found out it takes a little time to sink..
Thats why I think its B for this one .
Also the water won't be enough for it to sink.
how do you know its paper????
DeleteIm just guessing that what it is because its a solid and paper can float some times...
Deleteso thats why hannah .
The awnser is (A) becaues if you punch holes in it then it will sink
ReplyDeleteI agree because the more water sinks in the more it will sink.
DeleteI agree with Milan too.
DeleteYou have to say why you agree!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (saying in nice voice)
DeleteHannah it is like you are reading my mind! Love that!
DeleteI think that the answer is "A" or "B". Whenever you put a hole in a boat the boat will sink, but I don't think Mrs. White was using a boat. It also depends what she was using. If she was using styrofoam it would float. I will probably post another comment saying another answer.
ReplyDeleteI just reread the question about 10 times and would like to change my answer. It said the materiel was thin and could float. I remembered I have done an experiment to answer this question. I had a candy wrapper and punched a hole in it and put it in water. It floated. Punching a hole in something will not effect its density. I think the answer is "C".:D
DeleteBut Noah the paper might weigh more than the rapper you used ..
DeleteC might not be correct
but it could be c ..
I put B..
But maybe Im wrong
I mean it might weigh a little bit more
DeleteBut Carolina the paper has less density and the less the density the more it will float.
DeleteNoah, the question says, "punches holes all the way through it." You said you only punched a hole in the candy wrapper.
DeleteI agree with Carolina because it won't stay the same it would have a diffrent mass because you punch holes through it so it won't float the same.
DeleteI don't agree with C or B because when water enters through the holes, the material gets heavier and heavier until it sinks.
DeleteI think is (b)because it will not have enough water to make it sink, and if you think about a tube it has a hole and still floats.
ReplyDeletei think its b because the holes would make it barely float
ReplyDeleteI disagree Andrew because the water will comw=e inside of the boat thingy
DeleteOMG how do you guys know what the floaty thing is :( <---- confused face
DeleteI also think the answer is B because the water will start going on to the material but, the water won't sink the material all the way.
ReplyDeleteI also think the answer is B because if you punch holes in it water will start getting on it but the water won't have enough force to sink it.
DeleteI agree with Remi and Izzy I think the answer is B because if it is thin I think the water can come up on top of the material causing it to go down some but not sink entirely.
DeleteSorry Elizabeth I have to disagree because it says "punches a hole all the way through". I think the answer is A.
DeleteI think its (A) because if you punch holes in it the water will go threw the holes which the water will force it to sink
ReplyDeleteI think its A because the more air goes in, the more it will sink like a paper clip
ReplyDeleteI think it is A because if Mrs. White punches holes into the material the water will go through the holes and sink.
ReplyDeleteI think the answer is C because I think the holes do not matter.Since you are taking out parts, it would probably be less dense. If Mrs.White was using paper,it would float no matter what. Also, most of time, a thin, solid piece of material will float.
ReplyDeleteI think the answer is A because the holes in the object will make the water go above it and pull it down and make it sink.
ReplyDeleteI think it is B because it does not have a much surface area but it still has some so it should still float
ReplyDeleteI think it is b because when you punch wholes in it water will barely be coming on to it. But it will still float.
ReplyDeleteI agree with Fay because if you punch holes in it there will be room for the water to come through but if it floated the first time then there are little holes with air in them to make it float and if you punch the holes into the _________ those little holes with air inside of them will still be there so I think the answer is B. it will barely float
DeleteI think B because if there are holes in it,it will sink
ReplyDeleteI think the answer is A beacuse the water will come up through the holes and on to the top of the material and evetualy it will sink.
ReplyDeleteI disagree because even though it has holes, the water will barely make it in.
DeleteI think it is A because even if it only makes in a little bit the material is thin so it cannot withstand a lot of pressure then it will sink then more water will come in then it will sink and it said she already put it in the water , so the water will be in the material already it was aluminum foil it would still sink cause it can only hold a little bit of weight
DeleteThe answer is B. When the material has holes in it, it will sink but not that quick. It will still float, but not throughly. For example, if it was an index card then it would float but with holes, the water will barley make it to the holes. If you disagree, please comment. :)
ReplyDeleteI agree with Meggie the water won't sink the meterial :)
DeleteREAD MY COMMENT ON YOUR OTHER COMMENT ABOVE THAT I POSTED
DeleteI agree because although the holes were punched, it still will be able to float (ex. piece of foil floats, with holes it still floats.)the holes don't really affect the buoyancy.
Deletehow do you do your profile picture?
DeleteI agree that the answer is B because the thin piece of material won't sink all the way even though the water is going through the hole so it would barely float.
DeleteI agree because its only when you have many holes it will sink but if you have less holes it will barely float so I think it's B.
ReplyDeleteI agree with Meggie N.
ReplyDeleteI pick A because it has holes in it so water will get in. but cause it is thin it cannot hold a lot of wieght
ReplyDeleteI agree with you Kunhoo because with holes water will come inside so it will get heavier and sink
Deletei pick A because the hole punches just made the water go thorgh it and make the water push it down
ReplyDeleteI agree but it will have to bob so i think it is C.
Deleteso please tell me if i am wrong:)
ReplyDeleteI think that the answer is A. because the material is thin and it has been hole punched all the way through the THIN piece of material.There for my answer is A.
ReplyDeleteI disagree with you Madisyn. I thought it was A at first but just to be sure I experimented with this. I got a note card and put it in a tub of water. Just like the problem said, it floated . Then I got a hole puncher and punched a couple of holes in it. I put it in the tub of water and it floated. I even gave it a couple of minutes and it still floated. Then I took my results and thought about it. I figured out that the material with the holes punched in it was less dense. I remember in class when Mrs. Charles said "The less dense the object has the more it's going to float" therefore my answer is C
DeleteI think the answer is either (A) or(B). It would be (A) if it had big hols because the water would be able to go through the holes and sink it. It would be (B) if the holes are small because the water would not be able to go through.
ReplyDeleteI think it is A because the water will rise above the object because of the holes and cause the object to sink.
ReplyDeleteI think it is C because you may have punched holes in it but you have not changed the material itself. It would only sink if it bobbed and water came up an top of it to push it down.
ReplyDeleteJust to let everyone know i might not be my "I reply to everyone i think is wrong" self this time...ZZZZzzzzzz...
ReplyDeleteIt can be A or C. It would be A if it bobbed and water got on top to push it down. It would be C if she had placed it and it did not bob.
ReplyDeleteA seems like the anserw happy october
ReplyDeleteWhy? Remember you have to explain your answer :)
DeleteA. Because if you put something in water it might float and if it does and you put holes in it, it wil sink besauce it is loosing its volume and density. So then it will have less Density and Volume. And that is how Igot the answer.
ReplyDeleteI think the answer is B. The object can float. When the object has holes in it, it's most likely going to sink, but not that fast.
ReplyDeleteI think it's (B) because it will sink but the first time you punch holes it will float but eventually it will sink so (B) is what I think the answer is.
DeleteI agree with you Ethan,the answer is B. Although, like hannah said, it depends on what the 'material' is... parer might barly float, but light plastic or styrofoam would probably float.
DeleteI say B. because I assume it's paper. -tell me if I'm wrong.
I agree with Jessica the answer is A cause when the material had no holes it floated but since she made some holes the water will go through them and pull the material down so it will sink.
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteI think it will sink because water will go through the holes and puddle ontop of the paper and make it sink.
ReplyDeleteI think it will barely float becuse its not a really big hole and there is not alot of holes i think it will barely folat
ReplyDeleteI think it's B because it will float the first time. Meaning it will sink eventually.
DeleteI think the answer is a because water will come in and then sink
ReplyDeletei think the answer is B because she punched holes in the material so it might stay up for awile but it will eventually it will sink.
ReplyDeleteB because the water will just sit on top of the metal, causing it to barley stay up
ReplyDeleteit might sink eventually
DeleteHow do you know it's metal?
DeleteI think the answer is C because if the first time it floated then the second time you punched holes in it the object would still float.
ReplyDeleteI tested it out, and the first time it floated the second time I punched holes in it ,and it still floated.
DeleteSo, you are saying you think it is "C"? I'm just being sure... And I agree! I posted a comment that said I thought it was "D". But, after seeing your post, I think it is "C" too.
DeleteI disagree, Jake. Beacause if water gets on it,it will sink. So I think the answer is A.
DeleteI just reread the question and now I choose A.
ReplyDeleteI mean C.
ReplyDeleteI think that the answer is (A) because after the holes were punched the object would be abeal to take the water on faster so it will sink.
ReplyDeleteI think the answer is A because the holes let water in the water makes it more heavy which makes it sink.
ReplyDeleteI changed my mind I think the answer is C because when you punch the holes into the material the density will still be less than the water's density.
ReplyDeletei think that the answer is A because with out the holes in it it floated without the holes the air bubbles with the holes they can escape
ReplyDeletethe answer is "A" because the holes let the water go through so that means it will sink.
ReplyDeleteWhat I meant to say was I think that the answer is A because without the holes the object floated. With the holes the air bubbles will be able to escape from the object and it will sink.
ReplyDeleteI think it is A.Becausethe holes makes the material less dense as before.
ReplyDeleteI think that it will bob in the water because the holes let water in but the volume of the material has soft and light space so I predict that the soft and light material will bob in the water(D).
ReplyDeleteI think the answer is B because it is less dense but it still can float but just barely
ReplyDeleteim not a robot
ReplyDeleteI do not think that is what mrs.charles asked us to do.
DeleteI think the answer is A because the thin thing has holes in it.
ReplyDeleteI think the answer is A because its a thin pice of metal
ReplyDeleteWhy do you think it is metal?
DeleteI think it is C because it will always float unless too much water is on it
ReplyDeleteI think the answer is A because since she punched the holes through it the water will pull it down under.
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteI think it's b because the first time you punch holes it will barely float so b.
ReplyDeleteI thing the answer is A because the holes in the paper will make the metal sink in the water.
ReplyDeletehow do you know it's paper?
DeleteGood evening! I am so excited as I read all the posts. Want to know something funny? I don't know the answer! I think I have an idea but no way to tell for sure. So I thought we could do something interesting. If you want we can test out the problem. I saw that some people already have tested it out. If you want to bring in something "thin, solid piece of material" that already floats. (test it first!) then we will punch holes in it and see what happens! Sounds fun! You can list things in a reply to me so that we don't have a lot of the same thing. Just a thought!
ReplyDeleteThat sounds like fun! popsicle stick anyone?
DeleteI think the answer is A (it will sink) because the water can easily get through the holes, so it would make it much easier to sink. Think about it this way: If a ship had holes in it, would it sink or would it float (Anyone who has heard about the Titanic should know)? So, the obvious anw=swer is A.
ReplyDeleteI think it will sink because the holes let the air come out, and it will sink slowly
ReplyDeleteI am positive it is "A" because I have done this experiment before, and if you poke holes in the foil, the water goes up on to the foil which forces the foil to sink to the bottom. That is why my answer is "A".
ReplyDeleteI think is C just like Rachel C said Mrs Charles said (to Mrs. Whites home room) "The less dense the object has the more it's going to float" that is why my answer is C
ReplyDeletei disagree because i thin the awnser is a because the water can easily seep through the holes and water is sronger than air so the water would get on the material and push it down
Deletei agree with rachel
Deletei agree too
DeletePersonally, I believe that the object will float because poking holes in it will only make it float more freely.
ReplyDeleteI think the answer is A. If you punch holes through it the water will get on and push it down. If something has holes in it, it will sink. Same with the material.
ReplyDeleteWow there are a lot of ansewer out there but,I thing it is A because if you punch holes in it water will get in so it will push it down.In are exsparement (do not knok how to spell that)one team had holes in theres and it did not work well.So i think it is A
ReplyDeleteTell me if I am rong please!!!!!!!!!!!!!
I think it's (B) because even thought i wasn't here when we did the boat experiment Molly M. told me that hers had a lot of holes in it just barely floated so thats why I think that it is (B). Please share your thoughts on my answer.
ReplyDeleteThis problem was harder than the last one.
I think that the answer is A because water will get into the boat and make it sink.
ReplyDeleteI think it is B because we did the experiment with foil and it floated barely because the water came through the holes.
ReplyDeleteI think the answer B, because the material is thin and does not enough mass to make it sink down all the way. The holes will make it sink a little, but not all the way.
ReplyDeleteI think the answer is A because if you punch holes in the material it will sink.Then the water will come through.
ReplyDeleteI think it is A because the holes will get through and it will sink
DeleteThe answer is a because the holes will prenvent it from floating
ReplyDeletei think the answer is A because if she punched holes in it the boat would sink becaus eit would fill up with water then sink to the bottom of the bucket. Anyone disagree with me?
ReplyDeleteI think the awnser is A beacuse if you punch holes some water will get in on top but will not sink.
ReplyDeletei believ it is a because with holes water will get through
ReplyDeleteI think its B because when Ms. White poked holes through the material and put it on water the material will float because theres air going through it.
ReplyDeletei think it is b because when she poked holes in it it is able to let watter threw but not anough to let it completley sink i did a expement about it
ReplyDeleteIt depends on what it is. If it's a sponge it will float until it soaks up the water even if it has holes going thru. I think it's B. It will still float but will sink down a little.
ReplyDeleteI think it is C because floating comes from material density vs. fluid density. If the solid floated before putting holes in it, it will float after punching holes in it. Only the volume changed, not the density.
ReplyDeletei agree with dan, because changing volume is happening, not changing density
DeleteI think the answer the answer is B because the holes in the material will allow water to pass through and prevent it from staying on top of the water.
ReplyDeleteIt won't matter if you puch holes it in or cut it in half or punch squares in it. The same amount of material is there to float vs the amount of material. C it will still float!
