Looking Closely At Decomposition: Our Rotten Research


Our Rainy Day Exploration
We had lots of fun on our rainy day Nature Walk.  We saw so many slugs out for a Nature Walk too.  We looked closely at them outside.  Then we decided to bring some slugs inside our class to observe them even more closely.
We made our new Slug friends a cozy habitat.  Welcome new Slug Friends. We hope you enjoy your stay.
We fed our slugs lettuce and gave them lots of water.  One day we came to school and there was a TERRIBLE SMELL! It was coming from our Slug Tank. OH NO!
That wasn’t the only thing in our classroom that looked and smelled a little stinky! Our Gourds have changed too.
 R.G: It’s so dirty.
A.G: it’s so yucky (Plugged his nose).
C.C: So stinky.
M.B: It looks like dead.
K.P: I see leaves and grapes.  They are cracking
 the grapes and the apple is dirty.
C.S: The leaves are dirty.
E.C: Their making soil.
D.D: Why is it doing that?
A.S: They are getting crunchy and old.
M.A: They are getting super old.
J.A: The apples are dirty.
B.D: The slug is dirty.
G.M: If you keep it somewhere it gets dirty.
R.T: I see berries.
M.A: The grapes are getting super old.  We need
 to take them out.
J.M: The leaves are changing colours.  They are
going to change colours again.
J.V: It’s so messy.
A.V: The leaf is slimy.
A.S: I see lines on the slugs.
N.G: The leaves are slimy.  The slugs are eating.
C.H: The slugs are going to eat the grapes.
E.L: It’s getting dirty because everything is
 getting old.
M.A: IT’S ROTTEN!
We wondered what we knew about Rotten.
One friend said. “It smells rotten!” We
 wondered what rotten means. Can our
 slugs and gourds both be rotten? We
 decided to investigate what we know
 about ROTTEN.
What Do We Know About ROTTEN
B.D: If you leave something in a can and it doesn’t get air, it goes rotten.
E.L: When you leave, leave lots of stuff in a bucket, and leave it for a long, it will get rotten.
N.G: When things get old, when leaves fall down and stay there for a long time, they get rotten.
J.A: If you put food in there.  It will be very, very rotten.
E.C: If you put food in the compost, the slugs will come.  It will be soft for the worms.
E.L: WE NEED TO FIND OUT WHAT THINGS GO ROTTEN AND WHAT THINGS ARE NOT ROTTEN.
EXPERIMENT TIME YES!
We made a list of things that we thought would rot and things that we thought would not rot. We recorded our choices on a chart.  Now all we have to do is find all of these things.
Things That will Rot **Things That Will Not Rot
Orange                            Potato
Carrots                            Plum
Pear                                 Water                           
Banana                            Soil and Sand
Apple (red and green)  Newspaper
Strawberries                   Lemon
Grapes                              Flowers
Lettuce                              Metal
Cherries                            Eggs Shells
Leaves (Outside)         Wood and Rocks
 
We wanted to know more about how things get rotten so we did some research on the internet. We documented our learning by writing and drawing pictures.
We watched a time lapsed video of rotting food. Here are some of our Rotten Research Observations: What do you see?
R.G: It is yucky, like a rotten banana. Bugs! The
strawberry melts first.
A.G: Really yucky! (Plugged his nose)
M.B: It looks like dead.
K.P: I see leaves and grapes. They are
 cracking the grapes. The apple is dirty. They are melting. It will smell like garbage.
E.C: They are making soil.
A.S: They’re getting crushy.
Makayla: They are getting super old. We need to take the berries out.  The strawberry disappeared. It melted. Garlic and potato don’t melt. The potato decomposed last. It will smell
like garbage. My food got rotten at my
Grandmas house.  We threw it in the garbage.
J.A: The apple is dirty. I see fruit flies now. The
 potato is the same. It will smell yucky.
C.C: The apple is getting from the dirt.
B.D: They are going into the dirt. It’s watery
 now. There are so many fruit flies now. It will smell like a skunk.
R.T: I see berries.
J.M: The leaves are changing to dark colours. It will smell icky.
J.V: It’s so messy. Garbage
A.S: The leaf is slimy, like play dough. Maybe
our things get gooey and slimy too. They’re
getting crushy. Some things melt fast and some
things take a little bit longer. It will smell like see
weed.
K.M: It’s squishy.
C.C: So yucky.
N.G: It’s yucky and squishy.
C.H: Like sea weed.
A.G: My banana was rotten and all black.
E.L: It is dirty because it is getting older. It
 will smell like poo. Ripe is good and rotten is
bad. It gets slimy.
A.J: It is all different. They changed.
M.A: The air is going out of the strawberry.
 It melted, getting smaller and smaller.  When it
rots, it gets smaller because air came out.
E.L: It is shrinking and changing shape.
A.V: It might be all gooey.
When things get rotten they change colour like green, white, black, gray and brown. They decompose and decay.
One friend said: "Out of decay, new things will
 grow.  Another friend added: Even flowers."
 Isn't Life Amazing!
 
Decomposition Experiment Step #3:
Create our Decomposition Diary Title page. We drew pictures of the things that rot and things that do not rot.

Here are our final Decomposition Diary Title pages.
We recorded our observations in our decomposition diary.  We looked at each item to see if anything changed.

It was getting so close to our Christmas vacation. We wanted to document any changes in our experiment.  So we made a chart to record our observations before and after the Christmas vacation. Here are our findings.
 
 

 

 

 


 
 
 
We still have more wonders about how things decompose. What should we do?
Now we know that some things take a little bit of time to decompose and some things take a long time to decompose.  We wondered why our water, metal, sand, soil, newspaper and rocks did not decompose at all.  Are there some things that never decompose?  
M.A: Let’s make a decomposition race. We can pick some things and see who will win the race.
E.L: We can pick something that we know rots very fast like a banana and a strawberry.
E.C: Why didn’t the newspaper decompose? It gets rotten in the compost. We need to put the things into dirt to help it decompose.
M.A: Our experiment stuff has to be in the dirt.
A.S: Maybe the banana won’t win the race if it’s inside the dirt.
E.L: To be fair, everything has to be in the dirt.
Then we received a special delivery in the mail.  It was a see through compost container.  This will really help us see which thing will win our decomposition race. 
We picked 3 things to observe how they decompose. We chose a banana, a crumpled piece of paper and a Styrofoam cup.  We wondered which one would decompose first.
Who will win the race?
  We looked at our 3 things.  We began to notice some changes. Here are some of our observations. We documented our learning by writing and drawing pictures.
Our Observations
B.D: The banana peel disappeared.  We can see the sticker.
E.C: The banana turned black and disappeared. The paper is not food so it didn’t rot, only fruits and vegetables.
M.A: I see a little bit more yellow near the sticker. The paper and the cup are not going to be like this.
J.A: The banana is black.  I see the sticker.

E.C: I see the banana rotten.  The paper orange a little bit.
J.A: The only one left is the cup.
E.C: The cup is not food or garbage.  I see a little yellow juice outside the cup.  The dirt have juice.

S.G: he cup is very dirty.  I see some yellow water.  The cup can’t change because is white.  The paper is clear.  I see some rocks close to the cup.  I see dirt.  I see the banana sticker, looks like a dollar.
E.L: The cup is the same.  I see the water yellow.  Smells weird.
J.A: The cup is making water.  I see yellow water.  The cup is paper not changing like the other paper.  The cup is covered with soil.  The cup is white and soil water.

Our Observations
K.M: The banana is gone.  The cup is yellow.
A.J: Banana is black.
R.T: The paper is yellow. The banana is gone.  The cup is yellow.
E.L: The banana is gone.  The paper is dirty.  The cup is yellow.

I.A: The cup is very dirty.
N.G: The paper is red.  The banana is gone.
M.B: The cup is brown.  The paper is yellow.  The banana is black.
We were looking closely at our decomposition experiment.  We noticed that the banana disappeared. We noticed that the paper is all crumpled.  But the Styrofoam cup is still there.  Some people thought that it changed and some people thought it did not change.
 
E.C: The cup did not change.
M.A: The cup didn’t get small.  We don’t want this garbage.
R.G: Maybe it doesn’t decompose.
A.S: Maybe it is going to change tomorrow?
E.C: Maybe we should leave it for 100 days.
R.G: I like 100 days.
B.D: It’s like a new experiment.
We decided to take the cup out to look at it more closely. We wondered if it would decompose after 100 days!  Stay Tuned.
 
First we looked at the banana. 8 Friends thought that the banana had decomposed and 20 friends thought that the banana was still there.
C.C: The banana is deep.  It’s hard down.
R.G: The banana is little like a circle at the bottom.
S.G: It’s very deep.
A.S: Maybe the hard pieces is the banana. We have to take all the dirt out.
E.C: The banana is a fruit.  It decomposes first.
C.C: The banana disappeared forever,  gone forever.
J.V: I can’t find it.  The banana is in the mud.
R.G: The dirt covered the banana.  You can’t see it anymore.
G.M: The banana is rotten now.

Then we looked for the paper. Where is it?  14 friends think the paper is still a rectangle shape and 1 friend thing the paper will not be all together.
J.M: The mud is covering the paper. I see it already.
M.B: I think the soil is covering the paper.
C.C: The paper is dirty.
B.D: The paper first was light and then turned to dark.
E.L: The paper is the same but the difference is that it is crumpled up.
A.S: The paper is wet.  If we touch it it will break and turn to half.
Now the waiting is over.  We can finally check to see if our Styrofoam cup has decomposed after 100 days. 7 friends thought that the cup would change and 18 friends thought the cup would not be changed.
E.C: The banana juice leaked to the other side on the cup.
C.S: The cup changed by getting dirty.
A.V: The cup was white and turned yellow.
M.A: The cup stayed the same. It just has a crack on it because it got crushed by the soil pushing it down.
E.L: We should get a new cup and compare it to the dirty cup.
C.C: I think it will be the same just not dirty.
M.A: The cup is still there.  We have too much garbage if we bring Styrofoam cups to school every day.
B.D: Maybe it will never go away.
M.A: That is not good.  It will hurt the earth.
E.C: We need to find out if it ever can decompose.


Will the Styrofoam ever decompose? Will it be on Earth forever?
E.L: We need to find out.  We can go on the internet to find out.
A.S: If it is true then we should never use Styrofoam ever again.
E.C: It hurts the Earth forever, even when we get so old.
Here is what we found out in our Decomposition Research.
How long does it take to decompose?


Glass: NEVER!
Cans: 200 Years!
Plastic: 1000 Years!
STYROFOAM: 1 MILLION YEARS!!!!!
E.C: That’s longer than the dinosaurs lived.
It is not good news! It is shocking! We need to take action now!
We need to make a promise to OUR EARTH!
That’s why we made a promise to eat only healthy foods like fruits and vegetables.  AND we have NO GARBAGE in our lunches or snacks. At the end of the day our garbage can is empty. We only have some recyclables like paper.

We have been recording and counting all the fruits and vegetables we eat each week.

You can count on Team Wonder World to take of the Earth.
That means:
No Plastic (unless we can reuse it)
No Glass (unless we can reuse it)
No Styrofoam
No Cans
No Packaging on our foods or snacks
Food Scraps go in our Compost
TEAM WONDER WORLD SAVES THE WORLD!!
Come And Join Us! 
We Can Save The Earth Together!
AMEN
