Grade 7 Cracked the Code of Cell Transport… and Shared It! 🥚
Our Grade 7 scientists turned a raw egg into a living lesson on cell transport — and then brought the magic of science to our Preschool, Grade 1, and Grade 2 friends! 💙
First, they soaked the raw egg in vinegar to dissolve the shell — leaving behind a “naked egg” with just its membrane. The egg swelled up, showing how molecules can move into the cell.
Next came the corn syrup test 🍯 — the egg shriveled as water rushed out, proving that big sugar molecules can’t squeeze through the membrane.
Finally, the egg took a colorful dip in dyed water 💧, expanding even more than before as water molecules rushed back inside!
Through swelling ➡️ shrinking ➡️ swelling again, our Grade 7 students made osmosis and cell transport come alive! And the best part? They confidently explained every step to the little ones, inspiring the next generation of curious scientists.

🔥 Grade 8 Scientists on Fire! 🔥
Our young chemists just proved science in action! First, they tested the Law of Conservation of Mass by reacting acetic acid + sodium bicarbonate in a closed system. Even with all the fizz and bubbles, the mass stayed the same—showing that matter can change form, but it’s never lost.
Then, things heated up with the Fire Bubbles Demo! 🔥 A safe and exciting experiment for students, it perfectly showed combustion, an exothermic reaction where ethyl alcohol reacts with oxygen:
👉 C2H5OH+3O2⟶2CO2+3H2O
The flames were spectacular—but completely safe—demonstrating how energy is released when chemical bonds break and new ones form.
Proud of our Grade 8 students for proving the laws of chemistry and bringing reactions to life! Keep experimenting, keep exploring, and keep shining!
Our Physics class took out of the textbook and into the workshop with their DIY roller coaster project — built entirely from cardboard, popsicle sticks, and imagination.
But this wasn’t just arts and crafts — it was Physics in motion:
They timed marbles racing down drops to calculate speed.
They proved velocity changes whenever direction changes, even if speed stays constant.
And they measured how a steep slope caused a bigger change in velocity over time — the very definition of acceleration.
Every loop, curve, and drop became an experiment. Students collected data, ran calculations, and saw first-hand how Physics explains the thrill of a ride.
What’s most impressive? Their roller coasters weren’t just creative — they were precision-built test tracks for real-world Physics.
Here’s to our Grade 11 & 12 physicists — proving that science isn’t just studied, it’s experienced at full speed!
