OSWEGO, NY â€“ Would you like to find a way to keep cool this summer?. Perhaps youâ€™re looking for a way to put a little spring in your step when you exercise.
Maybe you just want to be able to eat an entire ice cream cone before the treat turns into a gooey, sticky mess in your hand.
Some elementary students just might have what youâ€™re looking for.
Trinity Catholic School held its Invention Convention science fair recently.Â Students put their science skills as well as their imagination on display in the school gym.
Diane Jackson (of SUNY Oswego) was a judge for the science projects.
â€œThese students are very talented and resourceful,â€ she said. â€œI am really impressed by these projects and all the hard work the students put into them.â€
Mary Bornheimer invented a fan hat. The fourth graderâ€™s ball cap design had a pair of small fans that were attached to the end of the bill.
Annie Seo, another fourth grader, came up with the idea for a spring powered exercise shoe.
Fifth grader Phillips Cummingsâ€™ project looked at the effects of different liquids on seeds.
After completing the experiment, he found that his hypothesis was correct. The seeds he â€œwateredâ€ with cola and distilled water would germinate, and those he used apple juice, vinegar and rubbing alcohol didnâ€™t.
â€œWhen the planted seeds started growing, both the distilled water plants and the cola plants grew faster the first couple of days and then their growth slowed down,â€ he pointed out.
Sixth grader Alex Flack did a project to determine whether the color of a candle had any effect on how quickly it burned down.
â€œThe red candle burned faster than the others,â€ he said. â€œI actually though the white candle would be faster because there is less added coloring.â€
His classmate, Anton Porcari, wanted to see how good peopleâ€™s sense of smell really is.
â€œCan you know a food or an ingredient? Like if youâ€™re holding an apple, do you know itâ€™s an apple? Yes,â€ he said. â€œYou can know it if youâ€™re seeing it or tasting it. But I want to know if you can do that with your nose. Because, your nose is your most powerful weapon.â€
He placed five everyday ingredients in containers and listed six options for each. People sniffed and tried to identify the mystery item.
His conclusion was â€œvery far off from my hypothesis,â€ he said.
â€œI thought everyone that I tested was going to get it right,â€ he said. â€œBut they didnâ€™t do as well as I thought they would; most didnâ€™t get it correct.â€
Some of his choices â€“ a tangerine or orange, scallions or onions for example – were a bit tricky, he admits.
Kaitlynn Todd made a solar panel out of used soda cans.
â€œI wanted to see if I could generate heat using items from around the house without using electricity, thereby saving money for my family,â€ the fifth grader explained.
She created a panel with six cans across and four cans down; the cans were spray painted black.
She placed the contraption outside in the sun and hooked it to a thermometer in the basement.
The basement started at 56 degrees, and within 10 minutes the room temperature was up to 65 degrees and the next day it reached a high of 85 degrees, she noted. The panel could be created larger to generate more heat if needed, she added.
The room cooled overnight and warmed up the next day when the sun came out, she said.
â€œIt was a fun project. I used items that we had in our house,â€ she said. â€œThe total cost was $3.96.â€
Lynch Rabyâ€™s project was to determine which milk goes bad first.
He studied skim, two percent and whole milk.
â€œSkim milk lasted the longest. The two percent was next and whole milk went bad the quickest,â€ he noted.
Another sixth grader, Ana Alcasid, wanted to see how well people could tell time â€“ without a clock.
Using a stop watch, she timed subjects to see how close theyâ€™d come to determining when one minute had elapsed.
The older people tested had a larger percent of error than others, she said.
Classmate Clare Donovan experimented to see which battery would last the longest in a flashlight (if left on).
She tested Duracell and Energizer batteries.
â€œI found out, sadly, that my hypothesis was wrong and the Energizer lasted longer,â€ she said. â€œI was holding the flashlight (with Energizer batteries) going, â€˜when are you going to run out?â€™ I thought it was dying and it wasnâ€™t dying. It lasted nearly three hours; if youâ€™re camping and get lost, that is a long time.â€
â€œWhat did you learn from that?â€ Jackson asked.
â€œThat if my first hypothesis is wrong I have to come up with a new one an test that one,â€ Clare replied. â€œYou have to try again.â€
Some of the other projects and inventions included a no-drip ice cream cone (with flavored edible sides), a wind-powered flashlight, the perfect pickle server, a notched hockey stick grip, a pet food bag spout to make serving easier, and a lighted camperâ€™s jacket.
“I’m really amazed by the ideas these students came up with,” said David Friedlander, principal. “You certainly have to admit, our students have an awful lot of creativity.”
