The 3 Physics Trick No Teacher Tells You About

Image
  Physics is often seen as a complex and daunting subject, full of equations and theories that seem far removed from everyday life. However, this is not the reality. Physics is actually all about understanding the world around us, and it can be surprisingly fun! There are many simple yet fascinating physics tricks that you probably weren't shown in school. These tricks are not only educational but also serve as great party pieces.  Let's dive into the three tricks no school will tell you but maybe your physics tuition classes will: 1.Balancing Forks Trick  This classic demonstration of physics involves balancing two forks on the edge of a glass using just a toothpick. It looks like magic, but it's actually all about finding the centre of gravity. Here's how you can do it: Take: Two identical forks A toothpick A glass (with a thin rim works best) Procedure: Interlock the forks by sliding the tines of one into the tines of the other. Insert the toothpick between the tine...

Cracking Secondary 4 Science: Misconceptions To Clarify Before O-Levels

Image
  What’s the real challenge that most students face in secondary 4 science?  If you ask me, it’s not the volume of topics covered but the hidden misconceptions that slip past many, leading to costly mistakes in the exams. You may have a strong memory and good practice, but subtle things, like the differences between osmosis and diffusion, current that gets ‘used up’ in a circuit, etc. often lead to confusion and roadblocks.  Even if you are fully prepared to ace secondary school, these gaps of information can lead to careless mistakes on the exam papers. Proper revision of each concept in your secondary science tuition is essential.  But how to get the time to do that amidst school assessments and exam preparations?  Well, you’re forgetting the holidays!  The Nov-Dec break before secondary 4 can be utilized to fill these gaps and ensure you have maximum clarity regarding the topics. Before you start the new session head on, it’s essential that you have all...

Green Chemistry Breakthroughs Are Impacting Learning Habits In Singapore.

Image
  The future of chemistry is unfolding right now, and it is greener than ever. In Singapore, sustainability is not an abstract idea but part of the classroom. The Ministry of Education (MOE) integrates green chemistry principles directly into the pre-university curriculum through case-based learning. A 2025 study involving 18 chemistry teachers from 17 schools showed that experiential lessons enriched with sustainability concepts improved both teaching quality and student engagement. This reflects the Singapore Science Curriculum Framework, which emphasises Science for Life and Society . The framework calls for scientific literacy that combines knowledge, ethical responsibility, and sustainable practices. For JC and secondary students, this means chemistry is no longer just about formulas but also about reimagining how science can solve global challenges without harming the environment. What Green Chemistry Means in Simple Words Chemistry can be thought of as a toolbox. Traditional...
