DIXFIELD — Why do flattened straws sound like a kazoo once you lower up one finish and blow by them? And why does a wine glass full of water make a singing sound once you rub your fingers across the fringe of the glass?
These are a number 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 making an attempt his experiments and guessing how and why issues had been occurring, or not occurring in some instances.
It doesn’t matter what experiment Ionta confirmed, he needed them all the time to be considering, ‘How come?’ and ‘Why?’
With each experiment, whether or not it’s the tin can with a ribbon working from it that squawks out a particular message or the suction cups that nobody can probably pull aside except they know the trick, he desires the kids to consider the scientific ideas behind every of the experiments.
“As an illustration, you fill that jar with water, (with a screened lid) it goes proper by simple. (However) tip it over rapidly 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 identical time.
One other thought-provoking experiment Ionta confirmed the youngsters 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, suppose, ‘how do they try this?”
One woman stated, “They opened the jar and put the pickle in it!” whereas a boy provided that “the pickle was dehydrated once 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; in the event you reply a query, even when your unsuitable, you’re being scientific,” Ionta informed them.
After Ionta’s presentation, Isabelle Campbell, 7 of Peru, stated 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 preferred the query of how the enormous pickle received contained in the glass jar.
Olivia Jeselskis, 10, of Canton and her siblings, Alana, 13, and Callen, 6, additionally stated they preferred 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 stated, she likes the “magic of science.”
The final day of the library’s summer season studying program will embody a craft program for youngsters from 2 to three p.m. July 27.
