Week Twenty Nine - May 9th, 2025
Grades 6-12
Ensuring Additional Support for All Students.
This academic year we are launching a new support initiative for all students at GIS. Academic Priority is a system of academic support for students that they can access in addition to their regular classes across all departments.
Each department holds a session once a week. The exact timings and locations for each department can be found on the Academic Priority Schedule posted below. This is also available on ManageBac.
Academic priority is staffed by teachers from the departments, ensuring that students have access to the teachers they need. Any student who needs additional support, has a question or just wants to discuss a particular topic is welcome at Academic Priority. There are no fixyed topics for a session. The teacher will provide support based on the individual student’s needs on a particular day.
In addition, teachers make themselves available to any student who needs support whenever possible. We are looking forward to the impact Academic Priority will have on our students progress and attainment.
Please see below for the Term 3 schedule.

As part of their exploration into quantitative chemistry and solution preparation, DP1 Chemistry students successfully conducted an investigation to prepare a series of standard glucose solutions and construct a glucose calibration curve. Applying precise laboratory techniques, they prepared a standard stock solution and then carried out dilutions to produce a range of known standard concentrations. Each standard solution was reacted with Benedict’s reagent and heated in a water bath to induce a redox reaction, producing a colored precipitate proportional to the glucose concentration. Using a UV-VIS spectrophotometer, they then measured the absorbance at a specific wavelength of each solution to generate a standard curve showing a positive correlation between concentration and absorbance, enabling future determination of unknown glucose concentrations. This hands-on investigation deepened their understanding of molar concentration and analytical instrumentation, which are essential skills in both chemistry and interdisciplinary biomedical contexts.
Grades 6-10
The finals of the ChallengeME Maths Competition took place during the weekend of 18th and 19th April. We had 6 finalists competing: Andrei Putin 7E, Jacob Salides 7E, Ayaansh Thapliyal 8D, Sedra Mansour 8C, Javad Ashrafov 10B, Zaineb Zouaoui 10C as well as semi-finalist Yuvni Mutha 6C who competed in the semi finals in early February. Javad and Jacob were awarded Silver in the finals, ranking them in the top 50 of all competing students and Andrei, Ayaansh, Sedra and Zaineb were awarded Bronze in the final, ranking them in the top 100 of all competing students. Congratulations!

In this investigation, DP1 Biology students examined the effect of temperature on the permeability of beetroot cell membranes. They measured the release of the red pigment betanin, caused by membrane disruption, using a colorimeter and/or a spectrophotometer. These instruments were used to quantify the absorbance of pigment in the surrounding solution, providing a quantitative measure of membrane damage. As temperatures increased, students observed a rise in absorbance values, indicating greater leakage due to protein denaturation within the plasma membrane. This allowed them to identify the thermal death point, the temperature at which membrane proteins begin to unfold, lose structure and function. The lab deepened student understanding of membrane structure, protein function, and the impact of heat on cellular integrity.
