What this article covers: How UK organisations choose, judge and commission STEM educational videos, covering curriculum alignment, accuracy control, outreach applications and the production process behind custom animation.
Who this is for: Marketing managers, training managers, education publishers, awarding bodies, and SME owners in science and engineering sectors who need STEM content produced to their own specification.
Key takeaway: Free STEM videos answer general questions well. Any organisation with a specification to meet, a brand to protect or an accuracy standard to uphold will need commissioned animation rather than borrowed content.
Expert insight: “The best explainer videos feel like conversations with knowledgeable friends who genuinely want to help.” , Michelle Connolly, Founder and Director, Educational Voice
Quick facts:
- Educational Voice has produced over 3,300 educational animations for LearningMole
- The studio works from Belfast with clients across Northern Ireland, Ireland and the UK
- Production examples across education, healthcare, finance and manufacturing appear on the studio portfolio
STEM educational videos have changed how science, technology, engineering and mathematics reach learners of every age. A single well made sequence can show a chemical reaction, a tectonic shift or a working circuit inside two minutes. For schools, employers and awarding bodies, the question is no longer whether STEM videos help. It is which ones to use, and where those videos ought to come from.
That second question is the one most guides skip entirely. Free STEM videos are plentiful, and plenty of them are genuinely excellent. What they cannot do is match your specification, carry your name or answer to your accuracy checks. Educational Voice is a 2D animation studio based in Belfast. It works with organisations across the UK and Ireland on that gap between watching and providing.
This guide is written for the person deciding, not the person browsing. It sets out when free STEM videos are genuinely sufficient on their own. It also covers when only commissioned work will do, and what separates STEM educational videos that teach from those that merely entertain. Curriculum fit, accuracy control, outreach programmes, quality checks and the shape of a production brief all follow below.
Why STEM Educational Videos Work as a Teaching Medium
STEM educational videos work because most STEM concepts are about change over time. Video is the only medium that shows change over time directly. A textbook diagram of plate tectonics freezes one moment. An animation shows the plates moving, colliding and buckling, which is the actual idea being taught.
The same holds across the disciplines. Sound is a pressure wave travelling through a medium, and a still image cannot show travel. Electrical current is flow. Cell division is sequence. Orbital mechanics is motion. In each case the static representation asks the learner to do the animating in their own head. Many learners simply cannot.
There is a second mechanism at work. Narration and visuals can carry complementary information rather than duplicating each other. When they do, learners process both channels at once and retain more. This is the basis of dual coding, a well established idea in cognitive psychology.
It also explains why STEM videos that read their own on-screen text aloud perform worse than those showing a process while describing it.
Scale matters too. Animation can show the very small and the very large on one screen at the same relative size. Educational Voice produces educational animation handling atoms, cells, machinery and planetary systems within a single visual grammar. That flexibility is difficult to match with filmed footage, and impossible with photography alone.
One practical consequence is worth drawing out. STEM educational videos are usually judged against textbooks, but the fairer comparison is a live demonstration. A demonstration shows the process once, at one speed, from one angle, to whoever happens to be in the room.
Animation shows it repeatedly, at any speed, from any angle, to anyone. That is the actual gain, and it is why the format suits revision and training equally well.
None of this makes video automatically effective. A poorly paced STEM video with dense narration and busy visuals will teach less than a good diagram. The medium creates the opportunity. Production decisions determine whether that opportunity is actually taken.
Library STEM Videos or Custom Animation: Making the Choice
Use library content when the concept is universal and context does not matter. Commission custom animation when the concept must map to a specification, carry your name, or show something that only exists inside your organisation.
That single distinction resolves most cases. The periodic table behaves the same way in every country. A general video about atomic number and element groupings will serve a curious learner perfectly well. A revision resource built around a particular GCSE or Leaving Certificate specification is a different object entirely. It needs the right terminology, the right depth and the right sequence.
The table below sets out the practical differences.
| Consideration | Library or free STEM videos | Commissioned animation |
|---|---|---|
| Specification fit | General coverage, mapping is coincidental | Built to your scheme of work or exam specification |
| Terminology control | Whatever the producer chose | Agreed at script stage before production begins |
| Branding | Third party branding throughout | Your identity, or none at all |
| Accuracy sign-off | No route to correction | Subject expert review built into the process |
| Ownership and rights | Licence terms set by the publisher | Agreed with the studio at the outset |
| Availability | Can be removed or altered without notice | Held as your own asset |
| Best suited to | General interest, enrichment, background | Assessed learning, outreach, training, regulated content |
The rights column deserves particular attention. A free video embedded in a course can disappear, get monetised, or change without warning. Organisations building a programme they intend to run for several years are quietly taking on risk. They are depending on someone else’s channel.
Educational Voice works with clients who arrive at this point having tried the library route first. The usual trigger is a mismatch. Content covers the topic but not the specification. Footage teaches well but carries another organisation’s branding into a classroom. The animation consultation stage exists to test whether commissioning is genuinely warranted.
A hybrid approach is often the sensible answer. Free STEM videos can cover the general background, while commissioned pieces handle the parts tied to your specification or your organisation. This keeps budgets proportionate and puts custom production where it earns most.
The split usually falls along one line. General principles are shared knowledge and can be borrowed. Applied content, assessment material and anything showing your own processes cannot. Mapping your programme against that line before commissioning saves money. It also produces a clearer brief for whoever builds the STEM educational videos you do commission.
How Animation Explains What Learners Cannot See
Animation earns its cost when the subject is invisible, dangerous, too slow, too fast or too expensive to film. Those five categories cover a striking proportion of the STEM curriculum. That is why animation and science teaching fit together so naturally.
Consider Earth science. The planet’s structure, from crust through mantle to core, cannot be photographed. Neither can the magnetic field generated by the liquid outer core. Nor the field reversals recorded in the rock record. Animation renders all of it visible, at whatever scale makes the point clearest. The water cycle plays out over timescales no camera will capture.
Sound behaves the same way. Waves are created by vibrating objects compressing and expanding the air around them. In air at room temperature that disturbance travels at roughly 343 metres per second. It moves considerably faster through water, and faster still through solids such as steel. Frequency sets pitch and amplitude sets volume. The human ear typically registers between 20 Hz and 20,000 Hz.
Every one of those facts is a moving relationship. Animation is how you show a relationship moving, which is why science education video work leans so heavily on it. A diagram can label the parts. Only motion can demonstrate the behaviour those parts produce.
Chemistry offers the clearest case of all. Reactions happen at molecular scale, sometimes in milliseconds, sometimes hazardously. Animated sequences can slow a reaction down, cut it open and label it, then run it again at speed. Educational Voice draws on the same techniques used across its 2D animation production work for commercial clients. The requirement to make an invisible process legible is identical.
Engineering and manufacturing follow suit. Sub-sea equipment, sealed assemblies and internal mechanisms all resist filming. Animation opens them up. This is why the studio’s manufacturing sector work and its STEM educational videos rely on overlapping production methods rather than separate ones.
Matching STEM Educational Videos to the UK Curriculum
A STEM video that does not match your specification is enrichment, not teaching, and the two should not share a budget line. Curriculum alignment is the most common reason UK and Irish organisations move from library content to commissioned work.
Most highly ranked STEM video round-ups are written for a US audience. They organise material by grade level and cite American agencies. That leaves a real gap for anyone working to Key Stages 1 to 4.
The same gap applies to CCEA specifications in Northern Ireland and to the Junior and Leaving Certificate frameworks in Ireland. It applies equally to the national curriculum in England and Wales. Grade 6 is not Key Stage 3.
Alignment work happens at script stage, not in editing. A properly aligned production starts by naming the specification points the video must cover. Terminology, depth and sequence are then fixed against those points before a single frame is designed. Retrofitting alignment onto finished footage rarely works and always costs more.
Age banding is the other half of the problem. Primary learners need concrete representation, slower pacing and shorter runtimes. Secondary learners can handle abstraction and symbolic notation. Educational Voice covers this range directly. The studio’s guide to primary school animations sets out how production choices shift for younger audiences.
Organisations such as STEM Learning and awarding bodies including CCEA publish specification material that forms the starting point for this mapping. Any studio producing STEM education videos for a UK or Irish audience should be reading from those documents. A general topic list is not a substitute.
Video for STEM Outreach, Recruitment and CSR Programmes
Employers commission STEM educational videos for a reason schools do not. They need to show young people what a technical career actually involves. No library video can show your site, your equipment or your people, which makes this category almost entirely custom.
Engineering, energy, life sciences and technology firms across Northern Ireland and the UK all run outreach and early careers programmes. Those programmes face a recurring problem. A fourteen year old has no mental model of what a process engineer does all day.
A slide deck will not build one. Animation can, and it does so without the site visit, the safety induction or the scheduling difficulty.
The same asset usually earns its keep several times over. An outreach animation built for school visits often works again in recruitment materials, at careers fairs and in corporate responsibility reporting. Educational Voice regularly finds that a project briefed for one audience is specified to serve three. That changes the production approach from the beginning.
There is a further application inside the organisation. Technical onboarding and process explanation for new starters draw on identical methods.
That is why corporate training animation and STEM outreach content are frequently commissioned together. Both need accuracy, pacing discipline, and the ability to survive repeated viewing.
Timing matters for these programmes. Schools plan visits a term ahead, and careers events cluster in particular months. A studio brought in shortly before a fixed date has fewer options than one engaged early. Build the animation requirement into the programme plan rather than treating it as a late addition. That tends to produce better work with less pressure on everyone.
Sector context matters here. Regulated environments such as healthcare and financial services carry accuracy requirements that STEM content shares.
The studio works across technology, financial services, healthcare and education, applying the same review discipline to its education sector work. In regulated content a factual error is a compliance problem, not a minor edit.
Common Mistakes in STEM Video Production
The most expensive mistakes in STEM video production happen before animation starts, which is also when they are cheapest to fix. Four recur often enough to be worth naming.
Briefing a topic instead of an objective. A brief that says “explain photosynthesis” produces a video about photosynthesis. A brief that says “learners should be able to describe the inputs and outputs of photosynthesis” produces a video that teaches. The second is harder to write and far more useful.
Filling every second. Complex visuals need silence to land. Narration that runs continuously over a demanding animation forces learners to choose which channel to follow. Most choose the audio and miss the visual, which defeats the purpose of commissioning animation at all.
Deciding output formats late. Runtime, aspect ratio and caption requirements shape storyboarding. Discovering after delivery that you also needed a ninety second social cut means re-editing rather than planning. Good STEM video production settles this in the first conversation.
Treating accuracy review as a final step. Subject experts brought in at the end can only approve or reject. Brought in at script stage, they can shape terminology and depth while changes are still cheap. Educational Voice builds that review into scripting for precisely this reason.
A sixth mistake belongs to buyers rather than producers. Commissioning a STEM educational video without deciding who owns the source files leaves you unable to update it later. Science moves, specifications change, and branding gets refreshed. Agreeing at the outset what happens when an update is needed costs nothing then and a great deal afterwards.
A fifth mistake sits behind the others. Organisations often judge candidate STEM videos on how impressive they look rather than on what learners can do afterwards. Production polish is easy to assess and easy to overvalue.
A Quality Checklist for STEM Educational Videos
Judge STEM videos on whether a learner could explain the concept afterwards, not on view count or production polish. High view counts reward entertainment. Learning rewards clarity, and the two only sometimes coincide.
Run any candidate video against these checks before it enters a programme.
Accuracy and currency. Is the science correct, and does it reflect current understanding? Older videos on fast moving topics quietly become wrong.
Specification mapping. Does it cover the points you need, in the depth you need, using the terminology learners will meet in assessment?
Pacing and cognitive load. Does narration compete with dense on-screen text? Is there enough silence for a complex visual to land?
Visual honesty. Are scales, colours and simplifications labelled as such? Misleading representation is harder to unlearn than absence.
Representation. Do the people shown reflect the learners watching? This matters for participation in STEM careers, not just for appearances.
Audio clarity. Is narration clean and intelligible to a learner working in a second language or a noisy room?
Accessibility. Are captions accurate rather than auto-generated? Is essential information carried by more than colour alone?
Rights and permanence. Do you hold a durable right to use it, and will it still be there next term?
Educational Voice builds these checks into production rather than applying them afterwards. The studio’s animation examples show how the standards translate into finished work.
Commissioning STEM Educational Videos: What the Process Involves
Commissioning is mostly planning, and the planning stages decide the outcome. Organisations new to animation often expect the process to be dominated by design work. In practice the script and storyboard carry most of the risk and most of the value.
The studio runs seven stages. Discovery establishes the audience and the gap in their understanding. Script development fixes terminology and depth. Visual concept development decides how the subject will be shown. Storyboarding locks those choices before animation begins. Animation production follows, then voice-over and sound design. Optimisation and delivery close the project across the formats you need.
Subject review at the scripting stage is the step most often skipped, and skipping it is expensive. Correcting a factual error in a script costs a rewrite. Correcting the same error after animation costs a rebuild of every affected scene. The studio builds expert sign-off into scripting for this reason, particularly on regulated and assessed content.
Format planning belongs at the start as well. The same STEM content may need a long form version for a lesson and short cuts for social channels. It may also need a silent captioned version for a reception area screen. Deciding this early costs nothing, while deciding it late means re-editing. Character animation, motion graphics and whiteboard sequences each suit different STEM subjects.
Scale is a reasonable thing to ask any studio about. Educational Voice has produced over 3,300 educational animations for LearningMole. That represents sustained subject matter production rather than one-off marketing work. Organisations planning a series rather than a single video are right to weigh that difference. The team behind the studio can talk through what a multi-part programme involves.
Delivery platform shapes the brief too. For organisations running STEM content through online learning environments, the studio’s commissioning guide for virtual learning animations covers the additional considerations that apply.
FAQs
What format works best for a STEM educational video?
2D animation suits most STEM subjects because it handles abstraction, scale changes and process sequences without needing physical footage. Live action works well for real laboratory technique and authentic workplace settings. Many effective programmes combine both. The deciding factor is whether the subject can be filmed at all. Invisible, hazardous or very slow processes leave animation as the only genuinely workable option available to you.
How do we make sure a STEM video matches the UK curriculum?
Start by listing the specification points the video must cover, before any script is written. Share that list with your production partner. Agree terminology, depth and sequence against it, then have a subject specialist review the script rather than the finished animation. Educational Voice runs this mapping at script stage. That keeps alignment cheap to fix, and it prevents costly correction later in the build.
Why commission custom animation instead of using free STEM videos?
Three reasons: specification fit, accuracy control and permanence. Free STEM videos cover topics generally rather than matching your scheme of work. They offer no route to correcting any errors, and they can be altered or removed without notice. Commissioned animation carries your branding, follows your review process and remains your asset. For enrichment, free content is fine. For assessed or regulated material, it rarely is.
How long does professional STEM video production take?
Timelines depend on runtime, subject complexity, the number of review rounds and whether subject expert sign-off is needed. Scripting and storyboarding usually take longer than clients expect, while animation itself runs more predictably. Series work moves faster per minute than single pieces once the visual style is settled. The studio sets realistic dates during the consultation stage, based on the particular specifics of your brief.
Are STEM educational videos suitable for learners with additional needs?
Animation offers real advantages here, provided accessibility is planned rather than added afterwards. Controlled pacing, consistent visual language and the removal of distracting background detail all help learners. Accurate captions, clear audio and information carried by more than colour alone are essential too. The studio treats these as production requirements from the brief onwards, rather than as adjustments bolted on once the animation is finished.
Who commissions STEM education videos besides schools?
Employers running outreach and early careers programmes, education publishers, awarding bodies, universities, science centres and charities all commission this content. Manufacturing, energy and life sciences firms use it to explain technical roles to young people. Training teams apply the same methods to internal process explanation. Educational Voice works with organisations right across Northern Ireland, Ireland and the wider UK on all of these varied applications.
