ABOUT the lakeridge Science Fair 


Challenge Your Mind, Satisfy Your Curiosity.
The goal of the Lakeridge Science Fair is to inspire and nurture scientific curiosity. Our event is a celebration of science. Either as a presenter or as a spectator, we guarantee you will learn something new and have fun doing it too.


The Lakeridge Science Fair is a noncompetitive event designed to encourage students to experience the fun true nature of science: to ask questions and find the answers yourself! Every student will have a chance to present their project and discuss their findings.


Our goals for the Science Fair are:

  1. Show kids that science can be fun and exciting.
  2. Show kids that they can ask questions about anything and discover the answers by themselves.


Benefits to our students are:

  • Encourages independent thinking and a chance to think “outside the box”
  • Opportunity to investigate and explore a new idea
  • Builds presentation and data collecting skills
  • Gets students acquainted with scientific terms and thought processes


A Science Fair certificate and medal will be awarded to each child following their presentation.

parent testimonials

  • "My kids learned a ton when they did their projects.”
  • “My kids are inspired to try it next year. They had a blast just going and looking at the entries.”
  • “My child explained her project at least 20 times that evening and got better and better at her explanation and demonstration each time.”
  • “I watched my child’s discussions with the judge and couldn’t help but think that he was improving his verbal communication skills and building his self-confidence.”
  • “My child commented on the way home that the science fair was a lot more fun than he had expected.”
  • “We learned more about science and the process of conducting an experiment. We also had dinner, petted a corn snake, watched the Pacific Science Center show, and had some treats from the bake sale. Needless to say, our experience exceeded any expectations that I and my family had coming into the evening!”
  • “Our son loved the non-competitive aspect and listened intently to his judge’s feedback.”
  • “I loved the vast array of ideas that the kids came up with and their enthusiasm to share them.”
