PLE Science & Engineering Fair

PLE Science & Engineering Fair

March 24, 2022

All Projects should be submitted by March 23rd in order to be judged and presented.

This is NOT a competitive Fair; students will have an opportunity to interact with a judge for feedback.


Students may submit a Science Model or Experiment OR an Engineering Project.

If you like asking questions and exploring solutions, start with a SCIENTIFIC PROJECT.

  • The key to a good and manageable investigation is to choose a topic of interest, then ask what is called a “testable question.” Testable questions are those that can be answered through hands-on investigation by the student. The key difference between a general interest science question and a testable question is that testable questions are always about changing one thing to see what the effect is on another thing.

Science Model or Experiment

Things to consider:

  • Scientific Question: A scientific question can be answered through an investigation.

  • What is tested? Scientists call this an independent variable. This is the one thing the investigator chooses to change.

  • What stays the same? A variable that is not changed, and stays the same, is called a constant.

  • Data collected: Data can be qualitative, describes physical properties, or quantitative, uses numbers and tools to collect data.

If you like solving problems and proposing solutions, start with an ENGINEERING PROJECT.

  • Engineering is the application of science and technology to solving a problem. Invention is really about engineering a solution. For students, this can be: 1) A problem they want to solve; or 2) A process or physical design they want to improve.

Engineering Project

Things to consider:

  • Design Question: A design question asks how something could be fixed or improved.

  • Science Topic: Many times design questions are solved using Science, Technology, Math, and Engineering.

Have fun at home with your student doing Science and Engineering!

ALL PLE students may participate - Kindergarten through 6th Grade

Choose one of the three categories:

                  • Science Model (No Question)

                  • Science Experiment
