Introduction:
Last day we made an experience. That consists in checking if soya seeds can grow with polluted water.
Procedure:
To do the experience, we prepared different solutions with polluting substances(NaOH, NH3, NaCL). Each grup had one polluting substance and 4 petri sheet: in one of this, there was distilled water, in other, there was a solution with 0.1M of concentration, in other, there was another solution with 0.01M of concentration, and in the last one there was 1M. Next, we put some cotton wool in each petri sheet, 10 soya seeds, and the corresponding solution. We close the petri sheets.
