The giant room at West Hills Intermediate School seemed very small as dozens of would-be inventors and scientists displayed their projects to the public last Friday night.
The experiments ranged from the very simple to extremely complex, not always having the outcome as predicted.
Such was the case with ten-year-old Aiden Claypoole. His experiment was entitled “Elephant Toothpaste.” However, the premise of the experiment was to watch the effect when several compounds are put together. Aiden took peroxide and mixed it with yeast. The yeast works as a catalyst to release the oxygen molecules from the hydrogen peroxide solution. The oxygen-filled bubbles, which make up the foam, are actually the remainder of what happens when the hydrogen peroxide breaks down into water (H2O) and oxygen (O2). The bottle felt warm to the touch because this is an exothermic reaction in which energy, in the form of heat, is given off.
Aiden took the time to explain the process to everyone who came to see his experiment. However, he is really fascinated with the nuts and bolts of things and wants to be a mechanic some day.
Ariana Burtt is in Fifth grade. She used raw eggs placed over a flame and placed in water to create the illusion of it turning silver.
“When you put the burned egg into the water, the density of the water and the light makes our eye think it’s silver,” she said. “My Mom found it on Pinterest and I thought it was a kewl idea.”
Ariana hopes to become a teacher one day when she grows up.
