When Science Sticks: Girls in STEM Discover the Power of Bubbles

The Girls in STEM Club gathered at the Discovery Science and Technology Centre with curious eyes and eager hearts, ready to dive into a world of foam and fizz.  The lesson began with something simple yet fascinating, water.  Essential to life, water also holds secrets of its own.  The girls learned that water is “sticky”, not in the messy sense, but chemically, because its molecules like to cling to each other.

With plastic cups and steady hands, they competed to see who could create the largest meniscus, that tiny upward curve at the surface of water formed by the cohesion of water molecules.  The challenge sparked excitement, concentration, and plenty of giggles.

Then came the magic of soap.  The group discovered that soap is made of clever molecules: one end loves water (hydrophilic), while the other avoids it (hydrophobic).  This dual nature allows soap to trap dirt, clean surfaces, and, most importantly for today, make spectacular bubbles.

Eager to test their new knowledge, the girls jumped into hands-on experiments.  They blew bubbles using straws, loops, and even their hands, learning why bubbles are always spheres: because a sphere has the smallest possible surface area for the volume inside, nature’s most efficient shape.

By the end of the session, the room was filled with laughter, shimmering reflections, and floating bubbles of all sizes.  They did not just make bubbles, they understood them.  It was a day of discovery, science, and sticky fingers.  And everyone agreed: learning is even better when it pops.lving skills, all while having fun exploring real-world STEM applications.
