science+trail+to+Macritchie+Reservoir



====At the end of term 2, after the test we had a science trail in the Singapore Macritchie Reservoir. This science trail in the Macritchie Reservoir was to study for ecology and for us to relax after the test.====

====After reaching the reservoir, every one of us were given a blue booklet from the PUB for us to learn more about the reservoirs in Singapore and a handout for us to complete during the science trail. In the handout, there were many activities for us to complete. The first activity was to count how many different populations were living under a tree slump. It was not an easy job because there were many different tiny insects living there and it was hard to count properly. Upon completing this activity, we moved on to the next activity which was to find out the different properties of the water in the Macritchie Reservoir. These properties include PH, temperature and turbidity of the water. The result showed that the reservoir was a healthy environment for organisms such as fish and water plants to live in. :))====

====Afterwards, we went on to learn about the human impact on the reservoir. There are four main activities held in this reservoir. They are canoeing, fishing, jogging and natures walk. To me, these activities do not have negative impact on the environment. But soon I found out that even activities like canoeing can affect the eco system which has a negative impact on the environment in the reservoir.====

====In conclusion, I feel that this science trail was a very good learning experience. It enabled us to learn about ecology from the firsthand experience before we learn the more difficult part of the topic. This science trail was also very interesting as we were being able to see the real live examples of different populations, communities and habitats. Also, we get to test out the properties of the environment which was a brand new experience for me. Yay!====
