Science Expo 2019

Celebrate knowledge and discovery with us at the fourth annual Coquitlam Public Library Science Expo (CPLSE) for elementary, middle and high school students throughout the Tri-Cities.

Scheduled for Thursday, May 2, 2019, the Expo invites science-loving students to exhibit their amazing experiments for parents, judges and members of the public. Projects will fit into four categories: Elementary (grades 4 and 5), Middle (grades 6, 7 and 8), Junior (grades 9 and 10) and Senior (grades 11 and 12).

Students whose projects are judged best will win prizes – in the form of a cheque, as well as either a trophy or medal – for first, second and third place in each category. Each year, the Expo awards more than $2,000 in prize money to the young scientists who participate.

To be part of the Expo, students must submit a Registration Form and a Consent Form:

Consent Form

The deadline for submissions is Thursday, April 18, 2019.

We will include as many exhibitors as we can. However, depending on the volume of submissions we receive, we may not have space to include everyone who has tried to register. All students will be notified about the status of their project no later than Wednesday, April 24. 

You can find more information about the event in our introductory document: 

Science Expo Intro

Science Expo 2018

More than 300 people descended on the City Centre Branch on May 10 for the library's third annual Science Expo. Judges from the Faculty of Science and Technology at Douglas College interviewed the participants -- all students who live or go to school in the Tri-Cities -- and scored the projects. 

Highlights included:
  • A blood clotting experiment with implications for sufferers of hemophilia and acidosis
  • A way to reduce cavities using bacteria that infect other bacteria inside your mouth
  • An arm-strengthening sheath called the Exo-Elbow
  • An energy-saving lighting system that uses an Arduino computer with sensors to count people inside a room, then switch off the light after the last one has left
  • An experiment showing that background colour affects memory / word retention
  • An experiment comparing run-off on soil slopes covered with vegetation vs. plastic mesh vs. no stabilizing underlayer, and its implications for local fish-bearing streams
The ever-growing Expo featured 36 projects, compared to 31 the year before, and 23 the year before that. Winners receive medals (for second and third place), trophies (for first), prize cheques and bowling passes from Zone Bowling, a long-time supporter of the event.
Our thanks to all the participants, parents, grandparents, teachers, administrators, judges, and volunteers who supported the event, as well as our dedicated partners: School District 43 and Douglas College!
