  1. Introduction

Water pollution is harmful to the environment and our well-being and can lead to climate change, global warming and many other dire consequences. Thus, it is important to know if there are ways to stop or reduce the pollutants in the water. Thus, if water hyacinth is good at absorbing pollutants it could be used as a cheaper alternative when compared to other cleaning agents. Another plus is that it does it naturally, without the use of any chemicals 

A.R.C., G.D (2016) says that water­ hyacinth is a highly efficient absorber of fertiliser such as on nitrogen, phosphoric oxide and potash.

Rastogi (2016) says that when salt migrates into lakes and streams, it can harm aquatic plants and animals. A heavy influx of sodium and chloride ions will disrupt the ability of freshwater organisms to regulate how fluid passes in and out of their bodies.



1.1 Research Questions

We want to find out the effect of different amount of salt(NaCl) on the water hyacinth. 

      
We want to find out if water hyacinths are effective as a cleaning agent



1.2 Hypothesis


We expect the water hyacinth to absorb the NaCl present in the water 






Independent variable

The independent variable is the amount of salt in each cup.







Dependent variable 

The dependent variable is the concentration of salt(ppt) each day for each cup.





Controlled variables

(a)  The same volume of water used
(b) The same location the plants are kept
(c)  The same type of water used
(d)  The same type of salt used
(e)  The same type of plastic cups used
(f)   The same amount of time conducted for the plants.
(g)  the type of plant used for the experiment ( water hyacinth)
