One of the many activities at Kids of the Community this summer has been Science Experiment Day.
For an hour and a half, teams of children rotated between different stations to learn some science, have some fun, and prime themselves for a field trip to Hands-On Science Center in Tullahoma.
The 5-year-olds began with the station, “How many drops of water fit on a coin.” The children used droppers to deposit drops of water on plastic coins, counting how many drops a coin could contain before the accumulated water ran over. Occasionally kids would apply the water to their heads to ward off the midday heat.
The 6-year-olds worked at the “leak-proof Ziploc bag” station, at which Ziploc bags filled with water were poked with pencils to demonstrate unleakability.
The 7-year-olds started at the invisible ink station. The kids used a concoction of invisible ink, which included grape juice among other things, to write and draw on sheets of paper.
The 8-year-olds worked on making water float.
The 9- and 10-year-old girls used different ingredients to make Ooblceck, a white substance somewhere between a solid and a liquid that the participants reported felt like a less viscous kind of glue.
The 9- and 10-year-old boys started at the “Oreo cookie phases of the moon” station inside at the dining hall. Cookies were pried open, and the cookie end that contained the cream was manipulated (that is, you left all the cream, left certain amounts of cream, or removed all the cream) to show the different phases of the moon: new moon, full moon, waxing gibbous, waning gibbous, crescent, etc. Cookies were consumed during and after the station activity.
The 11- and 12-year-old girls worked on making closed sandwich bags expand and pop using vinegar, baking soda, and juju.
Finally, one of the most popular stations was the “exploding Diet Coke” where the 11- and 12-year-old boys were posted. Mentos mint candies were added into full two-liter bottles of soda to create some sort of pressure and make the soda shoot out of the bottle. Soda was consumed during and after the activity.
The groups of children rotated between stations so that every group got to participate in every station.
Haley Prater, a Kids of the Community summer staff member and a rising freshman at Warren County High School, chaperoned the 8-year-olds during the science experiment day. She said her kids liked the “leak-proof Ziploc bags” station and the invisible ink stations the most. “I think they enjoyed poking the pencils through the water bags,” Prater said.
Zoe Crichlow, an aspiring pediatrician and rising senior at Warren County High School, was Prater’s teammate with the 8-year-olds. Crichlow said she saw enthusiasm from her young charges at the “Oreo cookie phases of the moon” station. “Because they got to eat cookies,” Crichlow said.
Pacey Caffrey, one of the young participants in Science Experiment Day, described the Oobleck. “If you punch hard on it, throw something on it, it’s just going to be solid for you. If you go soft in it, it’s going to be like liquid,” Caffrey reported. “I saw it on YouTube.”
