A laboratory study is conducted to observe then describe the living things with their behaviour, movement, irritability, and other living things possesses.
This experiment is done using different set-ups that shows different number of organisms. Water from river, which is cultured for days exposed to sunlight, showed large number of microorganisms. Another set-up, the uncultured rain sample stocked on plants showed only small number. The 3rd set-up which is cultured water placed in dark place showed a larger number of organisms than the other two set-ups. Putting a sample in the cotton strand makes the organisms immobilized. Dropping salt solution, organisms moves away but dropping sugar solution makes the organisms move toward the solution.

An organism is any contiguous living system (such as animal, fungus, micro-organism, or plant). In at least some form, all types of organisms are capable of response to stimuli, reproduction, growth and development, and maintenance of homeostasis as a stable whole. An organism may either be unicellular (a single cell) or, as in the case of humans, comprise many trillions of cells grouped into specialized tissues and organs. The term multicellular (many cells) describes any organism made up of more than one cell.

In this experiment, a microscope is a vital tool in seeing these organisms. Before we do the actual laboratory, we were supposed to prepare a hay infusion. To prepare a hay infusion, we need to get water, either in ponds, streams, or lakes, any natural water will do, but not tap water because it is already chlorinated to remove microbes and in inhibiting the growth of microbes. Then, gather a handful of hay or grass and put it in the collected water in a container. There should be two set-ups for this so that we can test the living organisms in the presence
