I admit that we have the best educational system in this part of the world (Southeast Asia). But the culture here in Singapore dictates that we can never stop improving. Yes, complacency is bad, but so is not knowing when to stop. In an attempt to outdo their predecessors, educators set more and more “challenging” questions in order to show that the system is progressing under their watch. But how much is too much? When does one go overboard and start drawing legs on snakes when they finish first?
This experiment tests the capillarity of three different materials. The student is asked to choose the material that is most suitable for making a school bag. Just see how carelessly the question was phrased. The materials must be different. There is no point comparing if they were identical. In this case, you’re comparing three different materials with equal dimensions – not three identical materials.
Aiyoyo, teacher. Please try to get the basics right before you start drawing legs on snakes.
