Hollis Elementary PTA and Brookline PTO Science/Engineering Fair is proud to sponsor this each Spring open to all students K-6.  This event has been postponed at this time due to school closures and event cancellations caused by COVID-19. 

But wait, we now are having a virtual Science and Engineering Fair! The science fair rules have not changed, only the delivery and more creativity is needed. Using what you have and making substitutions for what you don't is encouraged!  Take pictures or video of your scientist explaining their project.  Post your project on our virtual Fair Facebook Page between April 15th and April 17th.  Then be sure to check out everyone's projects and provide feedback in the comments.


                               Hollis Elementary PTA/Brookline Elementary PTO Virtual Science Fair: 


Project Guidelines:

All students in grades K-6 may participate

Students may work alone, in pairs, or in groups of 3.

Students are asked to design and complete a project that is either:

  • Experiment
  • Invention or Re-Design
  • Model
  • or Collection (Grades K-2 only)

Parents may consult for the project, but please be more of a guide and let your child do the work. Be creative, no 


Be creative - use what you have for supplies and display.  Don't go out to get anything. Safety is very important.  The use of fire, matches, flammables, latex balloons, food samples to be given out, gas, and propane are not allowed.  


Please complete the registration form so certificates can be prepared later for participants: Registration Form


An Experiment:  In this type of project, students seek to answer a question- the hypothesis – which they set at the beginning of the experiment. It is not necessary for the hypothesis to be proven, in fact, it often isn’t. However, students need to follow the scientific method and show how they went through each step.

Scientific Method: More Info coming soon!



An Invention or Re-Design:   In this type of project, students can solve a real-life problem or take an existing design and make improvements to it. Students should follow the Engineering Design Process and show how they went through each step and the resulting data for each invention. It is not necessary for the invention to actually work, but it is necessary to show the process.  Models, prototypes, blueprints, posters, multimedia presentations or software demonstrations are all acceptable. 



A Model:  In this type of project, students demonstrate a particular STEM principle or fact. Students may wish to demonstrate how something works, a scientific phenomenon, or how something is created naturally or in the lab. Students should show how they used the steps of the Engineering Design Process to complete it.


Engineering Design Process: Diagram coming soon!



A Collection (for grades K-2 only): In this type of project, younger students make an assembly of natural objects that are labeled and grouped to show how they relate to each other and how they differ. Collections should include as many samples as possible to fully represent the topic such as sea shells, birds, nests, rocks, minerals, types of soil, insects, etc.


Celebrity judges are being sought to review and comment on all the virtual entries! 

This is not a school-sponsored event.
