Science Club Posters & Dancing Raisins

The students at Science Club have been busy combining creativity with curiosity.

First, they designed wonderful posters celebrating famous scientists from all different heritages. Each poster highlighted the achievements of pioneers in science, showing how diverse backgrounds have contributed to discoveries that shape our world today.

Alongside their artistic work, the club carried out a fun practical: the Dancing Raisins experiment.

When raisins are dropped into fizzy soda, they sink because they are denser than the liquid. Carbon dioxide bubbles from the soda cling to the raisins’ rough surfaces, acting like tiny flotation devices. This increases buoyancy, lifting the raisins to the surface. Once the bubbles pop at the top, the raisins lose buoyancy and sink again. The cycle repeats until the soda goes flat.

The students watched with delight as the raisins bobbed up and down like little dancers, learning firsthand about density, buoyancy, and gas release. It was science in motion - simple, visual, and memorable.

Magic Milk Experiment 

Science Club also explored the fascinating world of chemistry with the Magic Milk experiment.

Milk contains minerals, proteins, and fats, which can be disrupted by soap. When the students added drops of food colouring to milk and then touched it with dish soap, they witnessed a spectacular display:

This movement disrupts the surface tension of the milk and pushes the food colouring around. The food colouring looks like fireworks because it’s getting bumped around, causing a colour explosion.

The soap breaks the surface tension of the milk. When the soap molecules head for the fats, they form spherical micelles. This causes movement and creates cool bursts and swirls of colour. After all the fat molecules have been found and equilibrium has been reached, there is no more movement.

The experiment was not only visually stunning but also a clear demonstration of how chemistry works at a molecular level. The girls learned how everyday substances – like soap and milk - can reveal the hidden forces of science in action.
