Question

Collect water from two different water bodies around you and study of ph clarity and presence of any living organism in water observations

Answer 1

Procedure:

Reach the center of the pond in a small boat.
Slowly immerse the Secchi’s disc into water vertically holding the rope tightly till the black and white segments of the disc disappear.
On reaching a particular depth, the disc becomes completely invisible.
Using a pin, mark the length of the rope when the disc disappears (say A cm).
Slowly pull up the disc till the black and white segments of the disc just reappear.
Using a pin, mark the length of the rope where they just reappear. (say B cm).
Using a meter tape, find the length of A and B.
Find the mean length (Say X cm) of the rope by the following method. X=(A+B)/2
Observation:

The value of X represents the depth of the photic zone up to which sunlight penetrates in the water body and photosynthesis takes place.

Precaution:

Students are advised to perform this experiment under the strict supervision of a teacher to prevent danger, such as drowning

Answer 2

Water Observations

Explanation:

1. Gather water from two diverse water bodies around you and study them for pH, clearness.
2. Study perception of the accompanying (Spotting)Common ailment causing living beings like Ascaris, Entamoeba and  Plasmodium.
3. pH and the mean length of the rope by the accompanying technique.
4. X=(A+B)/2. Perception We can watch countless various life forms in water test.  
5. Turbidity is the proportion of the general lucidity of a fluid.
6. Turbidity of the water body decides the profundity to which light can infiltrate and in this way influences the dispersion and photosynthesis of phytoplankton and macrophytes. The more turbid the water body, the less is the thickness of its photic zone (the layer of a waterway that is infiltrated by adequate daylight for photosynthesis).  
7. The pH is a proportion of the general measure of free hydrogen and hydroxyl particles in a fluid arrangement. Arrangements with a pH under 7 are said to be acidic and with a pH more prominent than 7 are fundamental. The pH of unadulterated water is 7 at 25°C.  
8. The pH estimation of a water test can be dictated by pointer color technique and electrometric strategy utilizing a pH meter. For routine purposes, the pointer color strategy, utilizing all inclusive pH marker arrangement or paper strips containing the pH pointers, is utilized.
