Week 4 | ABIS Broadcaster

Did you know you’re about 2 cm taller when you’re lying down compared to when you’re standing? It’s true! The force of gravity compresses the cartilage in your spine throughout the day.

We had a great real-world connection to this in our Grade 11 Physics class. Our very own Somil was brave enough to measure this effect, finding he was 1.5 cm shorter after standing up in the morning. This was a fantastic, hands-on way to introduce our topic of Uncertainties in Kinematics—understanding that all measurements have a degree of error and learning how to account for it.

Here’s a snapshot of what our young mathematicians and physicists have been up to this week!

Grade 11 Physics HL 🚀

We took a deep dive into Projectile Motion (the science behind everything from a basketball shot to a landing a food packet and car jumps!) and explored how to calculate the path of objects moving through the air. We also continued our work with Uncertainty Propagation, learning how small uncertainties in our initial measurements can impact our final calculated results.

Grade 12 Physics HL 🎉

A huge milestone for our seniors! We have officially FINISHED the syllabus! 🥳 The focus now shifts entirely to two crucial areas: intensive revision for their mock/final exams and the completion of their Internal Assessments (IA). It’s a very exciting and important time as they consolidate two years of hard work.

Grade 11 Math SL/HL 📈

This week, students completed their summative assessment on Straight Lines. We’ve now moved on to Quadratic Functions. The challenge here is not just to solve equations but to understand them deeply. In a single problem, students are learning to factorize a quadratic, write its equation in three different forms (standard, vertex, and factored), and then sketch its graph, seeing how the algebra translates directly into a visual shape.

Grade 11 Math HL 🔢

Our HL students pushed into the fascinating world of Permutations and Combinations—essentially, the mathematics of counting and arranging. We have also set the date for their upcoming summative assessment. Our next topic will be Systems of Linear Equations, where we’ll learn powerful methods to solve for multiple unknown variables at once.
