I have learnt many things from this outdoor classroom learning experience. I have learnt that Singapore has many water catchment areas and reservoir like Lower Seletar reservoir and Seng Kang Wetland, not only did i learnt about the importance of conserving water but also the water quality in Seng Kang Wetland. I understand through the experiment that the most fishes need oxygen to survive therefore the temperature has to be range from 20-30 degrees celceuis if not the amount of dissolved oxygen will be affected.
