Green Audit PBL Presentation (2E1)












The verbal presentation was held during the 2 periods of the week to assess the pupils on their PBL projects. Majority of the pupils did a good job and presented their audit findings clearly and concisely.
PBL interdisciplinary project was meant to invoke their problem identification skills through various data collection at different areas in the school. After they have collected their data, they need to select their problem area and work on the resources to solve the problem. From the Internet, they can research on their interest area and come up with innovative ideas to solve the problems that they have identified. The following pictures show the problem area that one particular group has identified and the discussion points on transportation.
Through this project, the pupils gained more awareness of the need for each member of the school to do his/her part in environmental care. They also see the need to encourage their fellow school mates in keeping the environment polllution-free and litter-free.
Studying in a litter-free and clean environment would help to enhance the teaching and learning around the school.

2E1’s Practical Experiments – Testing for presence of Carbon Dioxide Gas


The 2E1 pupils were conducting a series of experiments to test for the presence of hydrogen gas and carbon doxide. In this particular lesson. The pupils were observing the effect of carbon dioxide on the limewater (calcium hydroxide).

The enthusiatic facial expressions of these pupils show that they were engaged and interested in what they were observing. After the observations, they would record their observations in their Chemistry workbooks.

Sec 5A1/2 Practical Experiment on 'Investigating the Refractive index of Glass' T2 W7

The practical session conducted with the Sec 5As needs a special mention. The lesson was on 'To investigate the refractive index of glass'. Through the few years of teaching this experiment, I noticed that many pupils find it tough to see the image of the pins through the glass block to determine the emergent ray. Therefore, a short video clip of the experiment was done to show the pupils the important steps to perform this experiment.

After watching this video demonstration, most pupils can perform the experiment with minimal assistance and managed to tabulate their values.

It is good to constantly reflect on present practices to fine tune and to further improve the teaching methods to help the pupils learn better.
