Water Conductivity Level in Goa Gajah Essay Example

the Independent Variable To manipulate the independent variable different samples from different water sources will be used.

Maintaining the Controlled Variables

To maintain the controlled variables all the apparatus that are used will not be changed between samples, extra precaution are also taken concerning the distance between the copper and zinc strip so that they remain the same.

Processed Data Fountain A (S/m)Fountain A Uncertainties (S/m)Fountain B (S/m)Fountain B Uncertainties (S/m)Pond (S/m)Pond Uncertainties (S/m)Water Stream (S/m)Water Stream Uncertainties (S/m) 0. 010. 00110. 0090. 0010. 010. 00110. 010. 0011 Conclusion and Evaluation In conclusion I can say that my hypothesis is correct because the level of electrical conductivity measured in all four water sources in Goa Gajah turns up within the conductivity range of that of a normal drinking water.

One particular point of interest for me is the fact that all the water sources in Goa Gajah turns to have quite a similar conductivity level with one another. If only the conductivity level of the water from fountain A and B that are similar I wouldn’t be surprised, but the water taken from the pond and the water stream are also very similar to the rest. This uniformity of water conductivity made me think that maybe all the water sources in Goa Gajah are connected, of course this is just a theory.For my evaluation of this experiment, I think that it is a pretty good and easy way to find out the electrical conductivity of a certain body of water, but while that is where the strength of this experiment lies it’s also where the weakness lies, this experiment in the end can only be utilised as a qualitative

experiment since we have no true value.

I think that to improve this experiment we have to test the conductivity level of a specific water solution, that way we can have a specific true value to be used as a base also.
