Marymount Academy students took part is what was likely the world's largest ever science lesson Oct. 12.

Students from Grade 7, 8, 10 and 12 science classes took part in the attempt at a world record for the largest practical science lesson with the hopes of inclusion in the Guinness Book of World Records.

Different groups took part in this activity across Canada as the official launch of National Science and Technology Week 2012.

Following strict guidelines, students had to sign in, and the entire activity was documented with time-stamped video and pictures to ensure the group was following the outlined rules.

After a brief video introduction from Canadian astronaut Chris Hadfield, the students watched another short clip that demonstrated the two different experiments – “the Kissing Balloons” and “the Water Mister.”

Using simple materials such as balloons, string, plastic cups and water provided at each table, the students then worked together in groups to perform both experiments and document their findings.

Marymount science teacher Lise Callahan was the organizer for the event and made sure she followed all outlined instructions for her students.

“It seemed pretty simple at first,” Callahan said.

“Just sign up the students and provide the materials. However, I quickly realized that it was a much more involved process. We have to ensure that everything is done properly to be included in the world record attempt.

“The students have been quite excited leading up to this event and we are thrilled to be a part of it. At Marymount Academy, we have really outstanding students and knew that their enthusiasm for this project would be really high. I am proud of our school for participating and can’t wait to see if we do actually set the record.”

All of the participants had to submit their results by Oct. 19. They will find out soon if their attempt was successful for inclusion in the Guinness Book of World Records.
