The most common understanding of the term STEM is Science, Technology, Engineering and Mathematics. STEM can be a confusing title because it seeks to group a range of subjects which are distinct, yet have fundamental commonalities in their underlying principles.



Scientists study natural phenomena and create formulae to explain, or predict, the behaviour of light, sound, chemicals, energy, organic and inorganic materials, and the universe.



Technologists use Engineering, Science and Mathematics to make an existing task, process or item, safer, more efficient or more cost effective.



Engineers use a combination of Mathematics, Technology and Science, to design and build things and systems, in a safe and reliable way, at the lowest reasonable cost.



Mathematicians study the relationships between numbers to create formulae. Formulae can be used to create “models” of behaviour of the physical world and are utilised in Science, Technology and Engineering.


To assist in their fields, STEM professionals often use computers to solve complex tasks. Computers are becoming more common in every day life and their use is becoming crucial to all kinds of careers. The four basic computational skills that students should develop are:

Sequential Commands

Sequential Commands

The concept of using a number of simple commands to create more complex operations. This includes the concepts of which instructions to use, and the order, or sequencing of the instructions is required, to achieve a desired outcome.

Test Conditions

Test Conditions

The concept and use of the “test” instruction to modify the results, or perform a different operation, based on the values of the input data. Students need to understand which test to use, how many tests are needed and when to perform a test.

Repeating or “Loop” Operations

Repeating or “Loop” Operations

The concept and use of a loop to repeat a number of operations to achieve something. e.g. A 10 cm square can be drawn by repeating the following command, 4 times, “draw a line 10 cm long, then turn 90 degrees to the right.”



A subroutine is a set of instructions that calculates values, implements features, that are used repeatedly in a program.
e.g. printing, getting a command or data, calculating the square root of a number, etc. Students need to understand how to send a value or values to a subroutine and how a subroutine can send or “return” a value or values to the main program.

The Engineering Design Process

When Engineers need to solve a problem, they use a process known as the Engineering Design Process. This process can lead to new technology which solves a new problem, or solves an already solved problem in a new way. The Engineering Design Process is similar to the Scientific Method used by Scientists.



The first step of the Engineering Design Process is Ideation. In this phase the team considers what problem they are looking to address, and what Mathematics, Science and/or Engineering principles might be able to help them solve the problem. During this phase it is important to think through the following:

What is the problem?
Who has the problem?
Why is it important to solve?

Finding solutions

Finding solutions

Now it is time to start thinking about solutions. It’s best to brainstorm solutions and generate as many ideas as possible. It doesn’t matter how weird or wacky the suggestions are. Once this is done, each of these ideas should be discussed and measured against the original problem. Does it meet the requirements of the user? Are there parts of the idea which might work with another idea? The goal should be to collect one or more great ideas which are worth exploring further. These ideas will be refined and improved throughout the project.



A prototype is a test of the solution. It may not be the final version of the technology, but it should demonstrate the key elements of the solution and allow the design team to see how the solution might work.



The design process involves multiple iterations and redesigns of your solution. You will likely test your solution, find new problems, make changes, and test new solutions before settling on a final design.



To complete your project you will need to prepare to show it to others, so that they may understand the problem you are trying to solve, your process and your solution. Professional Engineers always do the same, thoroughly documenting their solutions. This presentation should not just be about the final solution that you came up with, but the whole design process. It should include ideas you tried, other things you might have liked to do with more time and ways you think your solution could been better.

The 5 Criterias of Judging

There are 5 criteria that the Judges use to score the projects, over the two rounds of virtual project presentations.

Explain the problem they are  trying to solve

Explain the problem they are trying to solve


Student should be able to explain why they chose the problem, who the solution is likely to benefit and talk about other similar solutions which they researched during the ideation phase of their project.

Describe the benefits of their  solution

Describe the benefits of their solution


Students should address the specific benefits of their solution, how it will solve the problem, and why it would be preferable to other similar solutions, if applicable.

Explain the formulae or  equations used

Explain the formulae or equations used


Students should be able to show the principles of any Mathematics used to formulate their solution, to a level appropriate for their age group. It is suggested that younger students may want to use a worked example as a memory aid.

Explain the scientific principles  used

Explain the scientific principles used


Students should be able to briefly describe the theory behind any scientific principles they have used to formulate their solution. Use of sources is encouraged. Older students should be able to talk about any flaws or limitations in applying the principles to their problem.

Describe any improvements to  their solution

Describe any improvements to their solution


Students should have thought about any improvements that they would like to make given extra time or resources. They should be able to talk about why these improvements would be beneficial.


Teams will be divided into 4 categories based on year group:









i.e. A team of year 5 and 6 students is eligible, but a team of year 8 and 9 students is not.

Suggested Themes

Teams may choose a project that addresses any one of the United Nations 17 Sustainable Development Goals. If a team needs some help in making a choice, we have highlighted four themes below, to get the brainstorming underway!


Gamechanger Category People


Gamechangers category prosperity


Gamechanger Category Place


Gamechanger Category Space

Alternatively, we welcome the use of themes belonging to the UN’s Sustainable Development Goals found here.

How to enter

This year’s Game Changer Awards Event will be judged virtually via Zoom followed by a Virtual Award Ceremony live streamed from the Game Changer Awards website.

To make this happen the Register Now link will require you/your team to provide:

  • The School Name, Year Group, Team Name.
  • Teacher name, email and mobile number.
  • Project Description 150 words (this is your project “pitch” describing your project from concept to solution).
  • An audio recording with each student in the team reading out the Project Description. The audio clip will be used in the final production to showcase your project during the Virtual Awards event.
  • A minimum of 10 photographs in a file like Word or PowerPoint showcasing your working model / prototype – please make sure these are good quality images in either JPEG, PNG or PDF format.
  • Video footage of your working model/prototype (optional) – this can be recorded using a mobile phone.

IMPORTANT: The images, video and voice recording will be used by our Judges to prepare for your project presentation during Judging Week and will also be used to showcase your project during the Game Changer Virtual Awards event on 16 December.

We will need parental approval if any students are featured in photos or videos.

Virtual Project Presentations

  • After you have submitted your entry, you will receive an email from the Game Changer Awards Event Manager to arrange a time for your team to present your entry to our panel of Judges.
  • Judging this year will be done virtually using the platform ‘Zoom’. You will be provided with a link to the Zoom meeting prior to your scheduled presentation time.

REMEMBER to prepare for your Virtual Project Presentation and practice with your team. Look at the judging criteria and think of the sorts of questions that you might be asked and agree on the answers as a team.

Virtual Awards Evening
