Gummy Bear Lab

Now it is time to do the last step in the scientific method-- COMMUNICATE YOUR RESULTS!
1. What was your hypothesis? Was it correct? Why or why not?
2. Which change was greater for your group volume or mass? Explain
3. Was there a change in the density of your bear? Why?
4. Share anything else you would like us to know about your bear or your experiment.
5. Your initials or your first names (no last names please!)

1. Our hypothesis wasn't correct. We thought to gummy bear would shrink.
2. Volume had s greater change. Volume had a change of 10 cm3 and our mass had a difference of 6.2 grams.
3. There was a change of .1g/cm3 in density. Day 1 had 1.3g/cm3 and day 2 had 1.4g/cm3.
4. Our bear was huge! And it tasted gross. Like watery jello.

A Scientist said...

1. yes our hypothesis was right. We thought that it would get bigger and it did.
2. The volume was bigger than the mass. the difference in the volume was greater.
3. Yes it changed, and the bear got less dense. It got less dense becaause it was in the water over night.

*Our gummy bear was named Ladis-lav!

1. Our hypothesis was correct because we said it would get bigger and mushy and gushy and thats what happend.
2. The volume changed by 10cm and the mass changed by 3g so the volume changed more.
3. Yes there was because the volume and mass changed.
4. When we picked it up out of the water it slipped out of our hands and splatted on the groung and fell apart so it was kind of hard to answer the questions.
5. Jesse and Jacklin.

A Scientist said...

1. Yes our hypothesis was correct because we guessed that it would expand and it did.

2. The volume's change was greater because the difference was 7.77 for volume, and the difference for mass was 5.1.

3. Yes there was a change in th density. Our density was less after it expanded, and we can't really explain that.

4. Our results our basically the same as our classmates(length, width, thickness, volume, and mass), but most of our classmates' bears' density increased while ours decreased.

our gummy bear travis grew larger with volume , density and mass

P.S. Travis T. and i Kelsey S. say ello

A Scientist said...

1. Our hypothesis was that the gummy bear would get bigger because the water would expand it. Yes our hypothesis was right because the gummy bear got bigger and when we ate it, it taste like water.
2.for our group it was the volume that changed the most because the water made it bigger so the volume became bigger.
3.yes by 10.5 grams. we think it changed because everything got bigger so then the density got bigger.
4.the name of our bear was Freddy and he was the cutiest thing in the world and he kicks gummy bear world history and we loooooooooove him more than any other owner of a gummy bear and we didn't eat ours because we are awsome. Jordan ate ours and he said ours was digcusting but freddy isn't because he is the best gummy bear in the world.

yooooo

A Scientist said...

1.Our hypothesis was correct because it did get mushy but we did not predict for it to get bigger.
2.The volume was because it had a bigger difference then the mass.
3.Yes because both the volume and mass changed.
4.It tastes bad.

Scott and Senthan

1. No, we gussed that it would dizzolve but it got bigger.
2. Their change was the same.
3. Yes because the water was sucked up
4.Our bear was really big and tasted lie jello

A Scientist said...

1)Our hypothesis was not correct, we thought that it would get a lot smaller and it ended up getting bigger.
2)The volume changed more than the mass but only by a little.
3)The density changed by 0.01g/cm3
4)Our resuls are almost identical to hannah and malyun's
Matt D. and Angelica Period 1

A Scientist said...

1. Yes oyr hypothsis yes correct our "travis" grew larger
2. volume 4.5

kayla said...

1) our hypothesis wasn't correct , & we thought that it would desolve .
2) the volume had the greater change , because it got bigger so the bigger it gets the more space it takes up .
3) yes , because our mass & volume changed by the more space that it took up after it got larger .
4) yes it changed , & everyone else's changed too . & it got less dense .

Dawuan & Kayla S.

A Scientist said...

1.Yes we were correct because it did get bigger.
2.The mass is because it showed the most difference.
3.Yes because the volume and the mass both got bigger, so the denstiy would.
4. It tastes nasty and its red.

riley said...

1. Our hypothesis was: If we put the gummy bear in water, then it will expand. Our hypothesis was correct, the gummy bear expanded.

2. The volume changed more. The volume went up by 12 and the mass went up by 5.5.

3. Yes there was a change of Density in our bear. Our density went down.

4. Our bear's color faded and was see through.

1. No it got bigger instead of desolving
2. It was an equal change
3. It got smaller because it got bigger
4. Ours was got a lot bigger and it tasted good! XD

A Scientist said...

1. Our Hypothesis was it might get smaller or change color.
2. Mass
3. No because it still weighs the same.
4. The gummy bear got bigger over night.

Alex P. and Shaunessy

1) Our hypothesis was right, we said the gummi bear would grow and get squishy because it absorbed the water.
2) Volume had a greater change, there was more space than matter in the new gummi bear.
3) Barely, the change was .16 g/cm3 beacuse all it did was absorb more water.
4) Ours was the same as our classmates.

Desi & Tyler. Hour 2.
1. Our hypothesis was that Mr. Gummy wold change color, it was kinda right. Instead of arange is turned a peachy color over night.
2. Our volume changed more. Volume changed by 8.45, and mass changed by 5.6
3. Yes, our density was less. Because the volume & mass also changed.
4. Mr. Gummy was tiny.. THAN BAMMMMM OVER NIGHT HE GOT BUFF!

A Scientist said...

no i thought it was ganna stay the same lol it got bigger and lighter (red)

Shawnee said...

1Our hypothesis was wrong because we thought it would either be smaller or break and it expanded and changed colors

2.our volume was bigger. our first volume was 3.75 cm and changed to 5.65 cm.

3. there was big difference in our density. ou first was 1.03 then went to 1.075

4. our bear was realy big but we didnt taste it.

D3 H4RTM4N said...

A Scientist said...

1. Yes our hypothesis was correct. We thought it would expand in size.
2. Volume change the most from 3cm to 14 cm.
3. Yes, it went up a little bit. The water does add more density but not much.
4.The gummy bear tastes bad. (Blake can't type fast)
5. Blake and Shane.

A Scientist said...

1.Our hypothesis wasn't correct. We thought that Charles (our gummy bear) would shrink, but instead it bloated.
2. Mass was greater because it was filled up with water.
3. Yes, because mass and volume changed.
4. Our bear is #1!!! :)
5. Sam and karli

hour 2

A Scientist said...

Becki and tom
1 our hypothesis was correct because we said that the water would enter the bears molecules causing an increase in volume an size.
2Our volume had a greater change then the mass because it increased by 8.5 but the mass increase by 6.3
3there was a change in the density because the volume increased more then the mass so it density per square cm decreased
4 It was squishy and yellow
5 Becki and Tom

A Scientist said...

1.If we left the gummy bear in water over night it will get bigger b/c of the water it will suck up.
2.The volume b/c volume=6.44 and mass=6.4 it was .04 more than mass.
3.Yes .B/c the volume and the mass change so the density change too .
4. nothing

Taylor & Maddy - Questions

1. No, our hypothesis was not correct. We didn't think the gummy bear would change at all.

2. The change in volume was greater. There was a volume change of 8.92 cubic cm. and a mass change of 5.5 grams.

3. There was a change of .01 g/cm3. Day one was 1.3 g/cm3 and Day 2 was 1.31 g/cm3.

4. The comments I've read have had similar results.

A Scientist said...

1. Our hypothesis was completly wrong. it was "It was going to disolve in water."
2. The mass changed the most because the water molocules moved into the gummy bear.
3. The density was greater because there was a greater mass.

Nicole and Art

Sara G. AKA Cocoa said...

1. Our hypothesis was incorrect. We thought that the gummy bear would shrin, but it actually expanded.

2.Our volume changed the most, we started out with 3.43 cm3, and then we got 15.2cm3.

3. There was a change in density also; we had .76g/cm3 before and now we have .51g/cm3.

Sara G. AKA Cocoa said...

The comment above is Carlene and Sara's

Tyler McG said...

1.Yes our hypothesis was correct because it did grow.

2. The mass was bigger because the water filled up the bear and then made it have more stuff.

3. Yes because the mass changed and that makes the result of the density change as well.

4. His name was cyclops and he was a great bear but his legs fell off. SAAAAD!!!

Tyler and Annie

A Scientist said...

1. Yes we said it would get bigger and it did.
2. The volume because it went up more than the mass.
3. Yes it went up .17 grams.
4. The bear was huge and tasted all watery.

A Scientist said...

1.our hypothesis was right. because we said that it would get bigger.
2.the volume had a graeter change, because it had difference of 8.58cm3 instead of 5.3 grams
3.the density was really different because the first day we got 2.05g\cm3 and today we got 1.2 g\cm3 instead.
4.ours stayed put together, and it felt like jello grosss!!!!

brunner43 said...

1. Our hyothesis wasn't correct. We were expecting it to dissolve.

2. The mass had a bigger change for us. The volume had a change of 5.005. The mass had a change of 5.4.

3. The density had a change of .12. The water probably got absorbed into the gummy bear.

4. The bear was big and slimy.

A Scientist said...

1. no our hypothesise was wrong. we thought the gummie bears would desolve.

2. mass had a greater change. ( v=4.8 M=5.2)

3. yes, because the mass and the volume (which control density) changed. it decreased.

RANDOM STUFF: Our gummie bear lost a leg. POOR STEVE! He got really buff though.

cheyenne & joe

cassie & marshall said...

1.Our hypothesis was correct we guessed he get bigger on Halimo's paper.
2.The volume was greater because even though it got bigger the mass still never changed
3.There was a change in density because when we first got it it was a different weight now the weight is less.
4.The bear's name is Yummy Gummy and she's ten
5.Samairrah,Sarwan,Halimo

cassie & marshall said...

Our hypothesis was the gummy bear would dissolve. Our hypothesis was incorrect because the gummy bear expanded instead of what we thought dissolve. Mass was the greater change because the mass change was 6.1 while the volume change was 6. There was a little change in density because it went from 1.05g/mL to 1 g/mL. Our bear's name was Phylis Wylis.

LEXI and AARON
1. Our hyphothesis was wrong. We thought that the color of the gummy bear woild disappear.
2. volume had a greater change. our volume change was 5cm3 and our mass was 5.1 grams.
3. Yes there was a change in density. The gummy bear was less dense after sitting in the cup for the whole night. It was less dense because it stretched out and had more space.
4. Our density decreased like joe and cheyenne. Both of our volume and mass increased.

thats it :D

cassie & marshall said...

Rebecca and Dancia
1. Half of our hypothesis was correct. We thought it would turn the water red, and desolve, but it only turned the water red. In fact, it grew bigger!
2. The volume is greater. The volume changed by 6 and the mass changed by 5.4. Therefore, the volume was greater.
3. The density didnt change because the volume and mass changed at the same rate.
4. Our bear was pretty big and it looked like the rest of the bears.

tim r. said...

Steven and tim said Are hypothesis was not correct, it got bigger.
the volume was greater
there was a chsnge in our density

andre said...

mitch and andre
1.our hypothesis was incorrect, we thought the gummy bear would get smaller but it grew bigger.
2.volume had a greater change but not by much.
3.yes their was a negitive change in the density of .45

said...

Lizzie and Natasha

1. Our hypothesis was wrong. We thought it was going to get smaller and it got bigger.
2. Volume had the biggest change.
3. Yes, there was a change in the density, because the mass and the volume changed.
4. Our bear's name was Owen. We didn'r name it. We also didn't eat him. Jesse and Richard did. That was sad, but not like shipping your kid off to prison school sad. Just sad.

Ryan said...

1. Our hypothesis was incorrect. We thought it would disolve in water.
2. Volume changed more than the mass did. The volume had a change of 14 cm3 while mass had a change of 6.3g.
3. The density lowered as it got bigger. As it got bigger, the volume got bigger and the atoms were less packed together.
4. Our gummy bear got really big.
.

ohhh its Kelsey .. said...

1.we thought it would shrink but it got bigger. we also said the color would fade into the water and it did so we were kinda right but kinda wrong.
2. the volume changed more because it soaked up water.
3. yes, because the mass changed so the density changed because mass is part of density.
4. the other classmates had similar answers but not exactly the same.

cassie & marshall said...

Miki & Megan
1. our hypothesis was just the opposite
2.The volume had the greatest change
3.THe change in density was .o3g/cm3
4.I agree with Hannahs group. SAME HERE!!

SarSten said...

Sarah Michelle & Whitney Marie;

1. Our hypothesis was somewhat correct. We thought our gummy bear would be gooey & it was...but we never thought it would get BIG!
2.Our Mass ended up having a greater change than the volume.On the first day our mass was 2.6 grams & today our gummy girl's mass was 8.2 grams.
3. Yes, because the volume and mass changed so we had to recalculate it...volume/mass
4. OUR GUMMY GIRL TASTED PRETTY NASTYYYY! TALK ABOUT A WATERED DOWN
TASTE. too-T-les * *
U

cassie & marshall said...

1. Our hypothesis was correct we thought the gummy bear would get bigger and slimmy.
2. The mass was greater
3. Yes there was a chnage in density its grew 5.15g/cm.
4. Our bear was huge and its was very slimmy and breakable andits tased really bad

Dallas Anderson said...

1. Our hypothesis was wrong. We thought our gummy bear would shrink when instead it got really big.
2.The mass was the greatest change, it changed 5.4 while our volume changed 3.48.
widthchanged 1
our length changed1.4
our density changed to 5.248

cassie & marshall said...

1.Yes our hypothesis was correct. We thought that the gummy Bear (Billy-Bob-Joe-Bob-Frank) would get bigger.
2. Our Mass changed the most it changed 5.6grams an the volume changed 1ml
3. Yes int did change because it gained more volume.
4. Our bear was really big. And it was really sugery and also veery mushy!!!!

trista said...

Andrew And Trista

Our gummy bear got a lot bigger just as we guessed.

Julio said...

My hypothesis was incorrect My gummy bear got bigger not smaller

trista said...

1.Our hypothosis wasw that the gummy bear was going to get bigger and it did. WE WERE RIGHT!
2.the volume was a greater change than the mass.
3.yes the density changed because the bear became more dence.
4.It changed color.

3 greams
it tasted ok

Tony Sipe said...

1. our hypotheis was correct we thought it would get big and it did!!!!!!!!!!!!!!!!!!!!!
2. volume had a change of3.95 more than it was ,my name is underdog(vvms) and bathound
3. volume is more than mass it had a big change
4.our results are pretty close to others

xoxo...JEN!! said...

Jen and Ian
1. Our hypothesis was incorrect, b/c we thought it would shrink.
2. volume was greater after then night in the water.
3.there was a small change in density b/cit expanded so much.
4. our bear was BEASTLY. but it taster horriblé. haha.

Sarah said...

1. Our hypothesis was that the gummy bear was goin to expand. We were correct, the gummy bear did expand.
2. Our mass was greater then our volume. On day 1 out volume was 1mL, and our mass was 2.6g. On day 2 our volume was 7mL, and our mass was 8.2g.
3.Yes there was because the water seeps into the gummy worm and adds more density to it.
4. Our gummy bear eventually completely fell apart.
5. Sarah, Stephanie

cherokee& cathy said...

1. yes our hypothsis was correct because we said it would expand and it (in other words it got bigger and that is what we guessed)
2.the volume had the greatest change because the volume changed 7 and the mass changed 6.5. also the volume was bigger in the begining so it had to be bigger in the end.
3.yes but not that much because it expanded so it kind of had to have grater density, so all the stuff inside expanded too.
4.they are probably going to have the calculations as we did.
-Kelsey and Jack Hour: 050

krazygurl101 said...

1. Yes becuase it got bigger and discolored.
2. Our gummy bear got a greater number in volume then mass because it got moree water in it.
3. Our gummy bear density Yes it did change because the volume and the mass went up..
4. Our bear was big! Tasted nasty. Like water and salt

DENNIS EHRHARDT said...

Dennis and Saria
1. We said the gummy bear would shrink size and dissolve. Our gummy bear expanded in the fresh water.
2.Our volume increased more to be seven times larger,. Meanwhile the mass quadrupled.
3.Our density changed with decrease. The water reduced the density and the mass and volume had different changes.
$ The bear became softer.
