Previous Winning Science Fair Projects To Inspire Your Creativity

Time. It’s something we all experience. But, when you have a science fair rapidly approaching and you still haven’t got any idea what to do for a project, time seems to go faster than ever!

Coming up with a science fair project is no easy task. If you’re stressing about it, then many others in your class will be too. The only difference is that you’re reading this article to get a head start on potential ideas.

Thinking of a science fair project can be more challenging than the project itself. Once you have an idea in mind, you can focus primarily on that and give yourself the best chance of winning the fair.

Previous Winning Science Fair Projects to Inspire Your Creativity

If you’re suffering from “writer’s block” and your usual creative flair is lacking inspiration, we have you covered. In today’s blog, we will be taking a look at previous science fair-winning projects to help get those creative cogwheels turning.

While we do not recommend copying any projects, some of the following winners from the past may inspire you into creating something similar but obviously better!

So, sit back, relax, and get inspired as we summarize hundreds of previous winning science fair projects for 6th graders through to 12th graders.

Why Partake In A Science Fair Project?

We understand that participating in a science fair project isn’t always your choice alone. Although many students decide to enter these fairs of their own volition, many must enter as part of a class.

Sometimes, pressure from parents makes students participate while others just like to challenge their scientific capabilities and simply have some fun.

Whatever motivates people to enter science fairs, the joy they can bring is what matters most. Let’s take a look at some of the top reasons to do a science fair project below.

The main reasons students participate in science fairs are:

  • To challenge themselves
  • To learn more about science
  • To design and make something that could possibly help the world
  • To explore new and exciting technology
  • To participate and do something that they can be very proud of
  • To win prizes. Sometimes, money is included!

The majority of students at science fairs are there as part of their class. While these science fairs are usually on a smaller scale, there are national competitions with over 1,000 participants.

If you take your science seriously and/or have a project in mind that you think could make a real difference to the world, then entering these national competitions could be the kickstart to a life of science!

There are also numerous maker events, engineering fairs, and hackathons out there, waiting for people like you to join. There has never been a better time to be a scientist with modern-day technologies and understandings growing every day.

Below are some of the national events that happen every year in the U.S:

  • Google Science Fair
  • JSHS Program
  • Regeneron Science Talent Search
  • Conrad Challenge
  • Regeneron International Science and Engineering Fair
  • Exploravision

Do a little research into each competition to see if any would suit your potential science projects.

Google Science Fair Idea Generator

If you’re still struggling to think of a science fair project, Google has a tool to help you. This idea engine takes advantage of a few search terms. This comes up with patents, websites, news stories, and more to help inspire you in creating a new project.

This tool allows you to combine certain things that you love with others that you are good at doing. You can create a project aimed at solving climate change issues or fuel-saving techniques. The possibilities are endless!

While this tool sounds amazing, it may not be the answer to your science fair prayers. When you type in various texts, the number of results can be overwhelming. Hundreds can come back instantaneously which can be hard to comprehend and understand.

Before you use the Google Science Fair Idea Generator, we suggest writing down “why does…” and “I wonder if…” questions for a week or so. This may help you come up with something more original than Google could muster.

Keep track of various questions you may have about the world around you. Keep a notepad on you or record your ideas on your phone. Other people may ask interesting questions too, which could spark some creativity in you. The more ideas you have, the better!

Review your list of ideas at the end of the first week and try brainstorming some potential experiments to answer your questions. If you’re still struggling, try turning to Google.

In Summary

The best science fair projects and, science experiments for that matter, attempt to answer a specific question.

As you can see with our list of previous winners above, many of them are simple questions such as “Dog or human: Who has the cleaner mouth?” or “How does sleep duration affect the body?”

Try and come up with a testable question. From here, you can create an idea and help it grow into your science fair project.

Try not to pick something too difficult unless you want a real challenge. Choose a fun topic. Something that interests you and excites you. If you have fun doing the project, it will usually show and give you a better chance of winning!
