DIXFIELD — Why do flattened straws sound like a kazoo whenever you reduce up one finish and blow by means of them? And why does a wine glass stuffed with water make a singing sound whenever you rub your fingers across the fringe of the glass?
These are a few of the science experiments Ted “Bitsy” Ionta of Dixfield demonstrates for youngsters throughout his shows.
On Tuesday, the retired science trainer introduced his demonstrations to Ludden Memorial Library the place kids took turns attempting his experiments and guessing how and why issues had been occurring, or not occurring in some circumstances.
It doesn’t matter what experiment Ionta confirmed, he wished them at all times to be pondering, ‘How come?’ and ‘Why?’
With each experiment, whether or not it’s the tin can with a ribbon operating from it that squawks out a particular message or the suction cups that nobody can presumably pull aside except they know the trick, he needs the kids to consider the scientific ideas behind every of the experiments.
“For example, you fill that jar with water, (with a screened lid) it goes proper by means of simple. (However) tip it over shortly and a tiny, tiny little bit of water will come out and the remainder of the water will keep in there,” he defined as he demonstrated on the similar time.
One other thought-provoking experiment Ionta confirmed the kids is a really giant pickle tightly packed right into a glass jar with some vinegar and a small opening to the jar. “How did they try this?” he asks his crowd. “If I present you one thing, assume, ‘how do they try this?”
One lady mentioned, “They opened the jar and put the pickle in it!” whereas a boy provided that “the pickle was dehydrated after they put it in” after which it expanded.
John Watson, 12, lastly received closest to the reply, saying, one thing “like a cucumber” was put within the jar with the vinegar.
“Yup, you’re heading in the right direction; when you reply a query, even when your flawed, you’re being scientific,” Ionta instructed them.
After Ionta’s presentation, Isabelle Campbell, 7 of Peru, mentioned a few her favourite experiments had been the one of many blob within the water jug; when it’s upright it seems to be like plain clear water and when it’s sideways it takes on a blob formation. She additionally favored the query of how the large pickle received contained in the glass jar.
Olivia Jeselskis, 10, of Canton and her siblings, Alana, 13, and Callen, 6, additionally mentioned they favored the blob within the jar of water, the pickle within the jar experiment, and the jar of water held again from dumping out by a display screen cowl. As Olivia mentioned, she likes the “magic of science.”
The final day of the library’s summer time studying program will embrace a craft program for youngsters from 2 to three p.m. July 27.
