There I was able to observe many organisms
other than earthworms. We took a soil sample from one place and then
went back to the lab where we put the soil sample into the tulgren
funnel. I then went and brought three more samples from the vermi-tech
pit. We then put these also into three other tulgren funnels. By then
it was lunch time and we all ate together. After lunch I weighed the
soil samples and got to see the organisms that were in the beaker under
the tulgren funnel. At 3.30 p.m I left for home.
11th November: In the morning, I was given two types of earthworms i.e.
Lampito mauritii and Perionyx excavatus and told to observe them. I
spent the whole morning doing this. After lunch, I wrote down the
observations that I had made. In the evening we went out to the College
playground and also to the area near the College Boarding to make some
observations. We dug two pits of 25 cm x 25 cm x 25 cm each at the
playground and one, of the same size, at the Boarding. We made many
observations which included the number and species of earthworms we
found and whether they were clitellates or not. We also made
observations regarding soil, atmospheric temperature and relative
humidity and took soil samples to measure the moisture content.
12th November: Left for New College as usual.
