When life gives you lemons — make electricity.With the LED tube
prices gradually drop, traditional LED
lighting supplier will inevitably be gradually replaced by Led Tube. he
believes that "the light pipe, no doubt, led the most promising market."

Well, that’s what 10 year old Gabe Davey must have heard, because instead of
fixing a refreshing summer drink, the Claude E. Garton Public School student
MacGuyvered a lamp using little more than the sour fruit and an LED bulb.

Davey’s experiment was one of over 100 science projects on display at
Lakehead University’s C.J. Sanders Fieldhouse gym on Tuesday. The Northwestern
Ontario Regional Science Fair had students from grades 4 to 12 from across the
region showcasing a diverse range of experiments.
“My goal in this was to
examine how many fruits it would take to light the bulb, and my question was
what fruit would take the least,” explained Davey, who pitted lemons, oranges
and grapefruits against each other in a battle of citrus supremacy.
Lemons
came out on top with only three needed to light up the bulb.
Fionna Fenlon’s
eye-catching experiment titled “How Haunted is Your House?” dealt with a phantom
of the energy kind — the electricity that household items waste even when turned
off, often referred to as phantom energy.
“It’s nothing about Ghostbusters,
sorry to disappoint,” Fenlon joked before explaining the worst perpetrators of
phantom energy, such as old TVs, desktop computer towers, and laptops that are
kept plugged in after they have finished charging.
Fenlon, a Grade 10
student from Sir Winston Churchill high school, tested different electronics
using a voltmeter and said that by unplugging rarely-used electronics, money can
be saved and our carbon footprint can be reduced.
Students could choose any
topic they liked, and like Fenlon, many had an environmental angle. Proof of the
importance that environmental protection was on the students’ minds.
For the
record, there were no exhibits either proving or disproving the existence of
ghosts, so that mystery still remains.
Chelsea Kubinec’s experiment may have
lacked a fun prop like a vinegar-fuelled volcano — and yes, there was a volcano
— but her experiment on how age correlates with gender stereotyping was just as
intriguing.
Kubinec said she was bothered by the way gender is portrayed in
marketing as well as the stereotypical jokes she heard from others, so she
created a survey that tested people’s beliefs based on their age.
“I focused
on gender stereotyping because I hear so many people make stereotypical
jokes,Bonded Copper cheaper, rolled copper is energy saving light more expensive.
Electrolytic copper by electrolysis the name suggests is that copper ions to
form copper foil to the substrate, so its features are: high electrical
conductivity, but is relatively weak resistance to bending; so I wanted to make
people aware that they are hurtful, and I wanted to display it with actual
results,” Kubinec explained.
The St. Ignatius High School student found that
older adults tend to believe gender stereotypes, but that the trend rapidly
declines for the 17- to 24-year-old demographic, a promising result to be sure.


Michael Kisro, a Grade 6 student from Sacred Heart School in Sioux Lookout,
built a miniature steam-powered boat using only copper tubing and a candle to
propel it forward, demonstrating the properties of steam and water pressure.

“I wanted to do a steam train but that would be a bit harder,” said Kisro,
who spent one day building the boat and another two constructing his board of
information.
Brendan Sawanas and Kansis Mandamin, two grade 10 students from
Thomas Fiddler Memorial High School, ran a series of tests to see if humans
could develop echolocation, the biological sonar used by bats and dolphins to
“hear their surroundings.”
Indeed, tests showed that blindfolded students
could make sounds and hear echoes to navigate. High-frequency clicking sounds
