Week 5

Week 5 marks the last time we are working on our microaquarium projects. It has been a long road with many interesting findings. The aquarium started out slow with few organisms swimming in the water. But over several weeks, with the addition of a food source, the amount of life forms dramatically increased. Several organisms were seen from week to week, such as the insect larva. I followed that larva from week one, and as far as I could tell, the larva grew every week. One organism I have yet to put in my blog is the simple Rotifer. Rotifers were by far the most abundant organism in my aquarium. It was just almost impossible to take a good picture of one because they are so small and very quick swimmers. I did happen to capture a fairly good picture this week during my observation time. Im happy but also sad that the project is coming to an end. It was fun following the different organisms from week to week. Until we meet again. Adios.
