Plants
Terra Layer: In this layer we have four green-leaved weeds, the tallest being 7cm, the second being 5cm tall and the shortest being 3cm. We also have a small Clover Plant growing, it is about 4cm tall and has three branches with many green leaves.
Decomposition Layer: In this layer we have three of the same type of weed as in the Terra Layer, but the tallest in this layer is 4cm and the others are both about 3.5cm tall. We also have a very small, silver mushroom growing in the corner.
Aqua Layer: There are no plants observed in this layer.
Animals
Terra Layer: In out Terra Layer there is a small, red centipede about 4cm in length and three small Wood-Louse we have identified living under the rock. There are no dead animals we can find.
Decomposition Layer: There are about 7 earth worms in the filter area of this layer and no other identifiable animals in this layer. There are no dead animals we can find.
Aqua Layer: We have hundreds of small, red beetles that can only be seen under a microscope which live in the water, they are clearly insect larvae. There is also another unidentifiable white insect larvae in the water. There are also about three small, brown water snails living in this layer. There are no dead animals in this layer.
Other Factors:
Water: The water seems to be the same colour as our last observation but the ater level has dropped by another 0.7cm.
Soil Level: The soil level in the Terra Layer has dropped by about 0.4cm.
Plants:
Terra Layer: In this layer, we have three small, green weeds and they are all about 2cm tall but one is almost 3cm. Our Clover we planted has receded a little but will probably start growing larger soon.
Decomposition Layer: We cannot find any plants in our Decomposition Layer.
Aqua Layer: The small, white mushroom is the same size as last time.
Animals:
Terra Layer: In our Terra Layer we can find one 3cm long, red centipede and four woodlouse that burrow in the soil and under the rock.
Decomposition Layer: In this layer we have about ten earth worms living in the soil and small ant-like creatures crawling at the top and on the sides of the container but they are extremely small.
Aqua Layer: In this layer we have hundreds of white and red insect larvae and many small, brown water snails crawling on the side of the container.
Other Factors:
Water: The water has gone about two shades a darker reddish brown, and the water level has decreased by 0.6cm since our last observation.
Soil level in Terra Layer: The soil layer in the Terra Layer has decreased by about 2cm.
Terra Layer: Our original weeds are not doing so well, their leaves are starting to wither and sag. New small, green weeds are starting to grow though.
Decomposition Layer: A small, white mushroom has started to grow in this section of the eco-column.
Aqua Layer: We cannot find any plants in this layer.
Animals:
Terra Layer: There is a small, red centipede living in this layer, it is about 3cm long. There are also about 4 or 5 woodlouse living in the soil.
Decomposition Layer: There are about 12 earth worms around the filter.
Aqua Layer: There are two different types of insect larvae in this layer and about five small, brown water snails.
Other Factors:
Water: The water seems to be the same colour as our last observation but the ater level has dropped by another 0.7cm.
Soil Level: The soil level in the Terra Layer has dropped by about 0.4cm.
