If you the kind of student who likes competition then you will find a good number of High School Competitions to participate in. This list of science competitions in this article is unique as the competitions here are open to middle and elementary school student.

Every year, thousands of High School students challenge themselves on online and offline science competitions, in math, physics, chemistry and other STEM subjects. And every year more and more students seem to show up in domestic and international competitions not only in science, mathematics, or STEM courses in general but also in writing, literature, critical thinking, problem-solving, debate and many other areas.

This makes it more difficult to figure out where to spend your time researching domestic and international competitions. With limited time and resources, it can be difficult for parents, educators, and students to know what science fairs and competition to take on or to figure out competition ideas that are available to compete for in other fields, other than science.

Stay Informed Group Team prepared this article to help parents, educators, and students navigate the world of academic completion for domestic and international students.

What is Science Competitions for Elementary and High School Students?

High School Science competitions

Science or scientific competitions for is an event organized by schools or other organizations around the world open for high school, and elementary students who are interested in exhibiting their science competition ideas. The feature of a science competition is that project entries use the scientific method to test a hypothesis.

Science fairs are not mere exhibitions of projects. The students present the results of their science projects in the form of a report, a blackboard display and/or models created by them. At science competitions, primary, secondary and elementary school students can take part in scientific and/or technological activities.

The ideas and goals of an international or domestic science fair or competition are for students to answer a question based on a hypothesis. Students often work on science fair projects in addition to their homework. Therefore, most entries of the science fair are generally modified versions of already existing experiments. Scoreboards help convey the nuances of a project to the judges, visitors and other participants in the science fair or competitions

The science competition also provides a mechanism for students with a keen interest in science to be partnered or merged with mentors from nearby colleges and universities to provide them with access to education and equipment available in the local school.

Benefits of STEM and Science Competitions for High School and Elementary Students

Indeed, STEM competitions provide an indispensable structure for those who just want to get into science, tech, engineering, and mathematics, while providing an opportunity for skill development for those who are more advanced in coding and developing games, Robotics and much more.

The benefits of science competitions for students domestic or international in middle school include the ability for students to think critically and, in some cases, work independently or work together as a team in others to improve collaboration and social skills.

Also, good competition for those who are just starting in the science or STEM related area can offer little pressure and a low entry barrier. Many other experiences with limit tests are available for advanced students.

As you can see, such Science competitions for middle school offer opportunities for everyone on the experience ladder. In any case, all participants can look forward to real problem solving, challenges that require practical participation and innovative thinking. We haven’t talked about the enjoyments and the pleasure factor that come from such competitions.

How to get started with any Science Competition

As mentioned earlier, the good news is that there are countless competitions ( STEM competition ) to think about, and more are added every year, some of which are only online and others require more personal participation.

The not so good thing here is that I have no idea where you live and I will have to do my best to list the best domestic and international science and STEM competition that I can find! This list is therefore fluid, and even if the year is rolling there have already been some opportunities which have gone, and new ones are still coming

How to win Science Competitions for Middle School and Elementary School Students

We have discussed some some tips that would help you win high school science competitions with ease. The tips will also be of benefit to elementary school students who are also looking science competitions for at their level.

High and middle School Science competitions  for students

Choose a topic that interest you

First of all, make ensure you choose a topic that interests you. It is said that, in science or general STEM competition, the person with the superior idea or ideas wins.

Once you’ve chosen a topic, do a lot of research. Learn everything about your topic. This is probably the most important step of all. Become an expert in your field, because this is what science fairs and STEM competitions for elementary and middle school students are designed for: they teach students an important scientific concept.

Plan your project

State the goal, discover the controls and variables, and build your hypothesis. Then make a plan of how you will experiment with it. Also, think about the possible data that results from your experiment. It is better to think about it before you even start the experiment.

Keep a laboratory booklet (also called an activity journal). Make notes, lots of notes, in your lab book. Don’t forget to record your goal, your process, your material, your variables (these are the things that change), your controls (these are the things that stay the same) and your data. This is important for all the science competitions for middle school students you can think of.

Make an assumption and test it

Remember, a hypothesis is a guess that is informed, not a question. one of the most important tips on how to win science competitions for middle school is to make sure that you don’t make assumption only; also test your assumption and know whether or not is is true as science itself is based on proven theories.


Don’t be discouraged if you have problems. It is natural and real scientists hit it every day. Judges also love perseverance, so stick with it. Indicate whether your hypothesis has proven to be true. Write your conclusion.

Find out what happened and why and document the result.

Make your display

Repeat your presentation in front of your parents, friends and family members. Listen to your parents’ suggestions, but also remember to take the dog’s suggestions with a grain of salt.
