St. Mary's Proves that Science Can Be Fun

Curiosity Drives Learning at the St. Mary’s Science Fair

Each group at St. Mary’s participated in the Science Fair. The Blue Group was interested in learning about the effects of sugar in our drinks. The group researched the amount of grams of sugar in drinks we consume. They took ten pounds of sugar and filled up Ziploc bags to show a visual representation of the different amounts of sugar in various, popular drinks. In another experiment, group members wonders what effect the fizz in Mentos candy would have when added to Coke.  Research on the internet led them to this experiment which turned out to be great fun. When the candy was put into a soda bottle, the bubbles broke off the candy’s surface, and the burst caused the soda to shoot out of the bottle. The bottle literally became a geyser and the soda shot high out of the bottle. This happened because the Mentos’ surface caught the small carbon dioxide bubbles and connected with them, turning them into much larger ones. This was a fun experiment, which can be replicated at home, but only with supervision!!!

Another experiment explored whether certain items would sink or float. Two bowls were filled with water, and the researchers added various items including a penny, feather, paper clip and an empty milk carton to determine the effect that weight has on whether items will sink or float. There was also a Skittles experiment which analyzed if the Skittles were packaged in the same way, with the same amount of colors in each package, or if the packing was more random. The latter was found to be true.

Another group constructed a volcano using a water bottle for the foundation of the volcano and then applying wet newspaper, via the paper mache technique, to form the volcano. The scientists added liquid soap, vinegar and baking soda to the bottle to cause the eruption. Lastly, another project presented their own “Umbrella Experiment’ to demonstrate the changes in the weather, how nature reacts to different seasons and what clothing is appropriate for these changes.

We are proud of our inquisitive and creative scientists, and we cannot wait to hear what IAHD – St. Mary’s is planning next!
