Eco-column

  In class we have eco-columns as you probably know.  You might also know that my partner is Judah.  We are doing experiments about them and the experiment that we are doing is putting acid rain.  We put in 5 drops of acid rain in one eco-column and 5 drops of plain water in someone else's.  Our hypothesis was that everything in the experimental eco-column would die and everything in the control eco-column would live.  (Our hypothesis was partly right since not only did the things in the experimental eco-column die but the things in the control eco-column die.)  All together I think we did very well.

  What I learned is that the ecosystem is very important and that you shouldn't take things out of there natural environment.  I also learned that it is better if you have a pH level of 6,7 or 8.  Our eco-column is a 6.  If you don't know what a pH level is, it is the level of acidity in whatever it is you are testing.  I will show what the different levels

  The world is an ecosystem.  An ecosystem is the world itself as in plants are a small part of the ecosystem.  The reason we made eco-columns is because then we can observe the ecosystem up close.  In all I saw many changes but the one that occurred most was that everything was dying.  I wonder why this happened because a pH level of 6 is good for fish and for snails?

Do you know why everything died?

Ecocolumn

At class we are making ecocolumns.  If you don’t know what an ecocolumn is, an ecocolumn is a terrarium on the top and an aquarium on the bottom.  In the aquarium we have fish, snails, elodea, duckweed, gravel , algae and of course water.  In the terrarium we have crickets, dirt, grass, leafs, twigs, rocks and anything we could find outside.

On Monday we finally got our fish and our crickets.  My partner and I got a white fish about 3 in. long.  Our cricket is like everyone’s.  The only thing that we got that no one else did was we got a worm it then gave birth to babies and now we have a bunch of tiny worms floating around.  I hope the fish doesn’t eat them one by one.

                                                              Have you ever had a fish?

                                                              Have you ever had a bug?

Science

In science we have made eco-columns.  That is an aquarium under a terrarium.  We have many biotic features such as fish plants and even bugs.  We also have many abiotic features such as dirt and water.  We have many biotic features that have given birth.  Like our worm when we got her she hatched an egg (it died because it fell and got buried under the dirt).  We also have a worm in the terrarium she is pregnant I know because she had a pouch and I know that means she is pregnant because they taught us at a farm.  Many things have died by now such as our fish and many of our isopods.

In our eco-columns everything depends on each other.  The crickets need the grass as food.  The snails need algae to eat.  The plants in the water need the snails carbon dioxide which is what snails give and the snails take the oxegyn which is what the plants give.  The bugs in the terrarium use the dirt to burrow and shelter like some bark and rocks that we have.

Do you have any living or non living thing you depend on?

Have you changed over time like our aquariums?
