This week’s Girls into STEM Club session explored the fascinating world of water and its incredible superpowers! The girls eagerly embarked on a series of engaging experiments that taught them about the unique properties of water while having fun.
The first experiment involved creating a water vortex. The girls gathered around, pouring water into a container and stirring it to watch a mesmerizing whirlpool form. Laughter erupted as they marvelled at how water could spin and create a vortex that pulled everything into its centre.
Next, they took on the challenge of keeping water in a bucket while spinning it. Through teamwork, they swung the bucket above their heads, giggling with delight as they discovered that the water stayed inside, demonstrating the powerful force of centrifugal motion.
Then, it was time for an intriguing air pressure test. Alissa asked one girl to help by putting on a rain poncho. She poured water into a glass, placed a small piece of card over it, and, with a sense of anticipation, flipped the glass up-side down. The card held the water in place for a moment, teaching the girls about air pressure creating a seal.
The excitement continued with an air pressure experiment using a glass and a candle. As they placed the glass over the candle, they watched the flame flicker and go out, marvelling at how water rose into the glass.
Finally, the girls discovered how water can protect us from fire. Alissa held a water-filled balloon over a flame, and the girls gasped as it did not pop, unlike an air-filled balloon. This powerful demonstration highlighted how water can absorb heat and provide protection.
By the end of the day, the girls left with smiles, inspired by the science behind water and its extraordinary capabilities.
Thank you, Alissa, for once more providing the photos and brief of the session.
