Sustainability with Aquaponics
Sustainability with Aquaponics
Students learn about the life cycle of plants and the factors that lead to growth of plants. Plants need light for photosynthesis. In aquaponics, natural sunlight or artificial lighting can be used. In aquaponics, water quality is essential because it's the medium through which plants receive nutrients. Proper pH levels, oxygenation, and nutrient concentrations must be maintained for optimal plant growth. Students also learn about nutrient levels, temperature and humidity as well as spacing and air circulation.
Game Based Learning
Game Based Learning
The use of games excite and engage students while ensuring the joy of learning. Students learn about the elements of the periodic table using Minecraft!
Our students took part in a Minecraft competition amongst many schools organised by Crescent Girls' School and was awarded the Master of the Block award!
Science Talent Enrichment Programme - scientist in schools programme
Science Talent Enrichment Programme - scientist in schools programme
Our school has a stretch programme for high ability science students who are passionate about science. They have been working with a scientist from A*STAR, Dr Kohtilil who has guided them in STEM, coding and physics mini research projects.
Section 1: Simple Refraction with Water
Activity:
● Set up a basic experiment using a transparent beaker filled with water.
● Shine a laser pointer or torchlight from air into water at different angles.
● Measure the incident and refracted angles clearly using a protractor.
● Record observations and results carefully.
● Use ChatGPT to learn Snell’s law.
● Use Snell’s law to predict the refraction angle. Compare it with the measured refraction angle.
Section 2: Comparative Refraction Experiments
Activity:
● Conduct similar refraction experiments using glass blocks, acrylic prisms, and other transparent materials.
● Measure and document the refracted angles carefully.
● Compare how different materials affect the bending of light.
● Can we predict the refractive index of an unknown material using incident and refraction angles of the laser pointer beam?
Snell's Law Calculation (Google Colab):
Write a Python code in Google Colab to automatically calculate refractive indices based on Snell’s Law, given incident and refraction angles.
Google Website Documentation:
● Clearly document each experimental setup, including step-by-step photographs.
● Provide detailed sections on methodology, collected data, calculated results, and conclusions.
● Include graphs comparing refractive indices of various materials.
● Personal reflection section from group members on their learning experiences, challenges, and discoveries.
Final Outcome: Each group will present on the Google Website showcasing:
● An introduction to refraction and its applications.
● Detailed documentation of experimental setups and findings.
● Calculations and comparisons using Snell’s Law.
● Reflections on the scientific and teamwork experience.
As a finale, the students wrote a Python script using ChatGPT and Google Colab to generate a HTML script to embed into the website. Some of our high ability students already went through Python coding class “tuition” by their own parents. Our parents are preparing their children for the future.
They proudly created a Snell’s Law Calculator each! Even those who do not have programming background learned to do that using the help of AI. Try out their applets here!

Below are some samples of their Snell’s Law calculators. There are so many possibilities for them to create their own applets, simulations, and scientific applets to manipulate variables as part of Inquiry!
