Wouldn’t it be great if someone walked you through science fair season, from planning to presentation? Your very own, personal science fair guide. While we can’t physically join you, we can give you a free printable science fair guide to take along for every step of the way.

While science fair sometimes ends with relief, it always starts with curiosity:

I wonder why…

What would happen if…?

Such questions form the basis of scientific inquiry, and your kids probably ask them all the time! A science fair project lets kids act on questions and discover answers. As they formulate a question, develop a hypothesis, design an experiment, and analyze the results, kids gain valuable critical thinking skills. When they design a presentation and interact with judges, they grow in confidence and public speaking ability.

You might be thinking, “That sounds great…but where do we start?”

Science Fair Guide

One science teacher and homeschool mom said this of our science fair guide:

“Thank you for the science fair guide. It is organized and informative. I appreciate that it gives a general summary and examples. As a teacher, I had more questions from parents concerning their child’s science fair project than from any other topic of the year. I plan to use this guide to help teach my children and others.”
– Jill S., Ohio
