Changes in the abiotic components

2013/02/21
  • We recorded the temperature in the class at 8:50am 2013/02/21. The teperature is 21.5 degrees celcius. 
  • The water in the water zone has created a lot of water vapour in all 3 zones (aqua, terra and decomp). 
  • The water level in our aqua zone is 7,4cm at the moment.


2013/02/28

  • The air temperature is 22 degrees Celsius in the room our Eco-column is in recorded at 08:51
  • There is still a lot of water vapour on the sides of our bottles.
  • The water level has stayed exactly the same (7,4cm)


2013/03/04:


  • The water level has dropped about 1mm, the water has evaporated by means of sunlight and spread to the rest of the eco-column
  • The temparuture in the class room is 25 degrees celcius, this was measured at 11:14am
  • The temparuture of the water is 26 degrees celcius. This was also measured at 11:14am

Other abiotic factors that may be affecting our eco column:

Our eco - column is on the side of the classroom where it will receive a lot of sunlight which will speed up the process of photosynthesis and the growth of plants. The windows and doors are usually open which allows a cold breeze to blow over the eco - column which will cool down the temperature of the water and air inside the eco - column on a warm day.

Who did what?

Nicholas 
Measured the temperature of the room
Measured the water temperature
Measured the pH of the water

Josh:
Measured the water level
Looked at the water under the microscope

Warwick
General observations
Looked at the soil under the microscopes

This is how we measure the temperature of the room:


This is us measurin the temperature of the water:

Changes in the biotic components


Our eco-column has sustained itself for 1 week now! Here are some observations of the biotic components:

2013/02/21
  • We added a spider in the terra zone last week and that spider has now died. We also added about 30 ants, and at the moment it looks like they are all still alive.
  • We found a small worm-like creature in our aqua zone. We will be adding a short video of the worm moving, that was taken under a light microscope.
  • The grandilla outer shell is slowly decomposing in our decomp zone.
  • The snail has started eating the tomato plants

2013/02/28

  • A plant has begun to grow from our decomposing piece of tomato (you can find more info on this here: http://leavingbio.net/plant%20responses.htm)
  • The growth of the plants in the Terra zone was great, the weed has grown approximately 2,5cm in height. There is nine leaves on the succulent plant.
  • Most of the ants has died as we can only see a few.
  • The water plants in the aqua zone has grown roots die to a lack of oxygen.
  • The tomato has almost completely decomposed.

2013/03/04

  • The ants were stuck tot the side of the terra zone because of the water vapour in the eco-column
  • The snail oin the terra zone has started to eat the tomato plant

Who did what?

Nicholas
Managed and counted the leaves and plants and observed the colour of the plants
Posted all info onto blog

Josh
General observations about the eco-column 
Measured the height of the plants
Observations under microscopes

Warwick
Managed and counted the animals in the eco-column
Reported extra information for me to post on the blog
Observations under microscopes


This is how our terra zone is looking at the moment:

Biotic components under a light and disecting microscope

On the 2013/02/21 our observations under the light microscope where dismal. We never found dead or living organisms from the water in our Aqua zone. Warwick and I were fascinated when we looked through the disecting microscope at the soil from the decomp zone, where we found fungal spores germinating and growing on the soil.

This was a shot of the fungal spores taken by the our biology teacher:


This is a cell shot of our water from our aqua zone:

EXTRA INFORMATION:

Fungal sporeswww.geo.arizona.edu/palynology/ppfungsp.htmlShare

Definition - Unicellular or multicellular, reproductive or distributional cells developing into a number of different phases of the complex life cycles of the fungi. Fungal spores can be readily classified by the Saccardian system, which relies on the number, shape, and placement of spore cells to classify the fungi imperfecti. Most fungal spores in pollen preparations probably are phaeospores (dark spores) of the fungi imperfecti, rather than ascospores, basidiospores, or spores of the lower fungi. However, repeating (asexual) spores of the basidiomycetes are very common in some sites.

This is a photo from the internet that looks similar to the fungal spores that were in our decomp zone

The worm-like animal that we found in our aqua zone: http://en.wikipedia.org/wiki/Multicellular_organism

The worm like creature is a multicellular organism. Multicellular organisms are organisms that consist of more than one cell, in contrast to single - elled organisms. To form a multicellular organism, these cells need to identify and attach to the other cells.
Only a dozen or so unicellular species have cells that can be seen individually with the naked eye. The rest of the nearly two million visible species are multicellular. In particular all species of animals, land plants. and filamentous fungi are multicellular, as are many algae. Some organisms are partially uni- and multicellular, like Dictyostelium.

The worm like animal is similar to the one we found in our eco - column, and observed under the light microscope.
