During the event, the James Buchanan High School pupil told attendees about how she’d collected bacteria and fungi from her grandmother's home.
“I wanted to basically figure out how many germs were floating around in the air,” said Samantha. The young scientist gathered samples from her grandmother’s bedroom, kitchen, basement, garage and barn, recorded observations and counted bacteria colonies over the course of two weeks. Her original hypothesis stated that the barn’s petri dishes would yield the most results due to the presence of animals.
“I’ve never used the excuse ‘my dog ate my homework,’ but this time, she really did," said the Mercersburg pupil. "She ate the petri dishes in the barn.”
In the end, it was the basement that offered the largest amount of microbes.
Meanwhile, two pupils in Bursa, Turkey have produced electrical energy by using the rainwater they collected from a roof. According to the Daily Sabah, Ahmet Emir Ceylan and Mehmet Enes Erdem of Dilek Özer Middle School ran the Collect Rain Water, Produce Electricity project. This was done under the supervision of teacher Eda Pınar Tüccaroğlu.
“We mainly produce energy from fossil fuels,” said Ceylan. “However, these resources are dwindling and pollute the environment. Our project neither need lots of funding nor pollutes. It produces clean and sustainable energy.”
The sustainable energy competition won 1st place at Science Fair Project Competition, which was held and organised by Bursa Science and Technology Center, Turkey’s most comprehensive scientific facility. It is part of the Ecsite European network of science centres and museums.
