An investigation undertaken to test a scientific hypothesis using experiments. Experimental variables, if identified, are controlled to some extent.


Sometimes you won’t be testing a new hypothesis, but you will be coming up with a novel approach to existing data.  You might not be collecting data, but analyzing existing data in a new way. Many studies are carried out using surveys given to human subjects.


A project involving the development and evaluation of innovative devices, models or techniques or approaches in fields such as technology, engineering, or computers (both hardware and software).


(Primary and Elementary divisions only)

Illustrates a known scientific principle. Does not investigate or prove an idea but shows an understanding of the concept. It could also involve re-testing an experiment already done.

All projects and exhibits entered in the Peterborough Regional Science Fair must meet the following criteria:

  • Under 21 years of age

  • Attending classes from Kindergarten to Grade 12:

    • home-schooled

    • a public, separate, private school​ or home school

  • Deadline for submitting entry fee and signature pages is Tuesday March 23, at 4 pm (four pm).  Late Entries will NOT be accepted. There are NO exceptions.

  • Deadline to upload your Project: Monday March 29 at Midnight

  • A project with two students is eligible but more than 2 students is not allowed

  • Students may not enter an identical project at any subsequent regional Science Fairs. However, a project may be improved and entered again to compete

  • A project cannot be entered in more than one regional Science Fair per school year for competition leading to the Canada Wide Science Fair

  • A student may not present more than one project each year

  • Except for grades K-3, a project summary (maximum 500 words) is required for the online registration. It is worth 10% of your mark. The summary is also used to determine the project's eligibility for special awards. It should include:

    • purpose of the project

    • brief description of procedures

    • brief summary of results

    • conclusions 

    • may also include any possible research applications

    • how to write a project summary

  • The exhibit can no more than 3.5m high, 1.2m wide and 0.8m deep, self-standing and stable. Exhibits which exceed these dimensions will be disqualified.

  • Projects must not involve living vertebrates except for observations of normal living patterns. No living vertebrates shall be displayed in exhibits. Parts of vertebrates slaughtered for other purposes are permitted. For details see the YSC Rules related to human and/or animal use

  • Entry fee:  $10.00 per student (a group project is still $10 per student) 

  • If 2 students enter a group project and they are in different divisions they will compete in the higher division


All projects and exhibits entered in the Peterborough Regional Science Fair must follow the following safety rules.

  • ​Exhibits must meet YSF safety regulations

  • Any display or backboard must be unlikely to ignite (three fold display boards found at stores like Staples are acceptable)

  • All hazardous or moving parts must be protected

  • Your exhibit does not contain pressurized containers

  • Your exhibit does contain any open flames

  • Any radio-isotopes are sealed properly and at normal background activity

  • Your exhibit does not contain flammable or poisonous materials

  • Power cables and switches must be supplied by the student and CSA approved, provide proper grounding and protected by fuses. Electricity (AC110 volt and 60 cycle) will be supplied but no gas or water outlets

  • Moving parts must be firmly attached

  • Cell or battery-fed circuits should be both safe in design and operation

  • All electrical connections are insulated

  • Any non-current carrying metal materials used are grounded properly

  • Your exhibit does not generate voltages above 10kV

  • Any exposed live components are at a potential of less than 36 V to ground.

  • Lasers are not operated during public display

  • X-ray and other high radiation sources are registered and approved by provincial authorities.

  • Live animals are not displayed at any point

  • Procedures or activities that could harm or distress have not been used in your project.

  • There are no biological toxins present in your exhibit

  • You have not performed experimental manipulations with recombinant DNA or animal viruses
