Every teacher has heard this line in an interview at some point:
"Can you take a demo class for us?"
More and more schools now want to see you teach before they invite you for an interview. A résumé tells them where you have worked and what you have studied. A demo video shows them something a résumé cannot: how you actually teach.
The good news is that you do not need a studio, a professional camera or editing skills. A smartphone, a quiet room, a whiteboard and five well-planned minutes are enough.
In this article, we walk through how to plan, record and share a short teaching demo video that helps you stand out, and how to add it to your EduStaff India profile so schools can watch it when they view your application.
Why Schools Want to See You Teach First
When a school receives many applications for one vacancy, the people shortlisting often face the same problem. Many résumés look alike: similar degrees, a B.Ed., a few years of experience, the same list of skills.
A short demo video helps them answer the questions that really matter:
• Can this teacher explain a concept clearly?
• Does this teacher speak confidently and pleasantly?
• Will students stay interested in this teacher's class?
• Does this teacher check whether students have understood?
• Is this teacher comfortable with the board and level we need?
A teacher with an ordinary résumé and an excellent five-minute demo can easily be shortlisted ahead of someone with a stronger résumé and no evidence of classroom practice.
Your demo video works for you even while you sleep.
Step 1: Choose the Right Topic
The most common mistake is choosing a topic that is too big. You cannot teach "Electricity" or "Photosynthesis" in five minutes. You can teach one idea within it.
A good demo topic:
• Covers one concept only. For example, "Why the sky looks blue", not "Light".
• Has a clear "aha" moment. A point where the student suddenly understands.
• Matches the level you are applying for. If you are applying for Classes 9–10, do not record a Class 3 lesson.
• Matches the board. A CBSE school will relate more easily to an NCERT-based topic. A Cambridge or IB school will look for inquiry and student thinking.
• Allows a simple demonstration or real-life example. Objects, diagrams or everyday situations make a lesson memorable.
If you teach more than one subject or level, you may record two short videos rather than one long one.
Step 2: Structure Your Five Minutes
A good demo video is not a full lesson squeezed into five minutes. It is a sample of your teaching, with a clear beginning, middle and end.
Use this simple structure:
0:00 – 0:30 — Introduction: Your name, subject, the class level and the topic. Keep it short.
0:30 – 1:15 — Hook: A question, a surprising fact, an everyday situation or a quick demonstration.
1:15 – 3:30 — Explain: Teach the core concept step by step, using the board, a diagram or an object.
3:30 – 4:30 — Check understanding: Ask a question, give a quick problem or ask students to predict something.
4:30 – 5:00 — Wrap-up: Summarise the key idea in one or two sentences and link it to the next lesson.
Notice that explaining takes only about two minutes. Schools are not testing how much content you can cover. They are watching how you teach.
Step 3: Teach to Learners, Not to the Camera
A demo that sounds like a speech or a news reading rarely impresses anyone. Schools want to see a teacher who is talking with students, not at them.
Even if there are no students in the room, you can still make the lesson feel interactive:
• Ask questions and pause: "What do you think will happen if…?"
• Respond to an imaginary answer: "Some of you might say… That's a good guess, but let's check."
• Use names occasionally, as you would in class.
• Address common mistakes students usually make.
• Smile. Warmth comes through on camera.
If you are currently teaching and your school allows it, recording a short part of a real lesson can be very powerful. However, always get the school's permission and parents' consent before recording students. A safer option is to film only yourself and the board, or to show students from behind without faces or names.
Step 4: Record With What You Already Have
You do not need expensive equipment. A reasonably recent smartphone records good-quality video.
Camera and framing
• Record in landscape (horizontal) mode, not portrait.
• Place the phone on a tripod, stand or a stack of books at chest height. Do not hold it by hand.
• Make sure both you and the board are in the frame.
• Leave a little space above your head. Avoid cutting off the top of the board.
Light
• Face a window or a light source. Never stand with a bright window behind you, or you will appear as a dark shape.
• Avoid harsh overhead tube lights directly above your face if possible.
• Do a 10-second test recording and check the result before you begin.
Sound
Poor sound will ruin a good lesson faster than poor video.
• Choose a quiet room and record at a quiet time of day.
• Switch off fans if they make noise, and close doors and windows to reduce traffic sounds.
• Keep the phone close to you, or use a basic clip-on microphone, which is inexpensive and makes a big difference.
• Put your phone on silent or flight mode so calls do not interrupt you.
Board and materials
• Write large and clearly. Test from the camera's position whether your writing can be read.
• Use dark markers on a whiteboard or white chalk on a clean blackboard.
• Keep your teaching aids ready within reach before you press record.
Step 5: Avoid These Common Mistakes
Many teachers lose the school's interest in the first minute because of avoidable errors:
• Too long. Anything beyond 6–7 minutes is rarely watched completely. Keep it close to five.
• A long introduction. Do not spend a minute on your qualifications. They are already in your résumé.
• Reading from slides or notes. It shows that you are not confident with the content.
• Turning your back to the camera for long periods while writing on the board.
• No student interaction. A lesson without a single question looks like a lecture.
• Factual errors. Check your content carefully. A wrong formula in a demo is very hard to forget.
• Distracting background. Clothes drying, cluttered shelves or a television in the background take attention away from you.
• Inappropriate dress. Dress exactly as you would for a formal interview.
Do not worry about being perfect. A small slip that you correct naturally can actually show that you are calm and genuine. Record two or three takes and choose the best one.
Step 6: Upload It to YouTube the Right Way
Once you are happy with your recording, upload it to YouTube.
• Visibility: Choose Unlisted. Only people who have the link can watch it, and it will not appear in public searches. Choose Public only if you are comfortable with anyone seeing it.
• Title: Make it clear and professional, for example: "Physics Demo Class – Newton's First Law (Class 9, CBSE) – [Your Name]".
• Description: Add two or three lines about the topic, the class level, the board and your subject expertise.
• Thumbnail: Choose a frame where you are looking at the camera and the board is visible.
• Comments: You may turn them off to keep the video focused.
Before sharing, open the link on another phone, while signed out of your account, to check that it plays correctly.
Step 7: Put Your Demo Where Schools Will See It
A good video is useful only if schools actually watch it.
• Add it to your EduStaff India profile. Your profile has a dedicated field for a YouTube teaching demo link. Schools browsing teacher profiles can watch your teaching straight away.
• Include it in your résumé. Add a line under your contact details or at the end of your professional summary, such as "Teaching demo: [link]".
• Mention it in your cover letter or application email. A short line is enough: "You can view a five-minute sample of my teaching here."
• Add it to your teaching portfolio and your LinkedIn profile.
Update your demo every year or two, or whenever you move to a new level or board. Your video should always reflect the teacher you are today.
Quick Checklist Before You Hit Record
Run through this list before every recording:
1. ☐ I have chosen one concept with a clear "aha" moment.
2. ☐ The topic matches the class level and board I am applying for.
3. ☐ I have planned a hook, an explanation, a question and a summary.
4. ☐ My lesson fits within 5 minutes (practised at least once with a timer).
5. ☐ My phone is in landscape mode, on a stand, with flight mode on.
6. ☐ I am facing the light, and both the board and I are clearly visible.
7. ☐ The room is quiet, and I have checked the sound with a test recording.
8. ☐ My writing is large enough to read on a phone screen.
9. ☐ I am dressed as I would be for a formal interview, and the background is tidy.
10. ☐ I have checked my content for errors, and I have permission for any students who appear.
Final Thought
A demo video is not about showing schools a perfect performance. It is about giving them a genuine glimpse of the teacher you are: someone who explains clearly, connects with learners and cares whether they understand.
Five well-planned minutes can open the door that a hundred applications could not.

Sample Script: Physics Demo – Newton's First Law of Motion (Class 9, CBSE)
Use this as a model. Adapt the wording to your own style. Timings are approximate. Materials: a whiteboard, a glass, a stiff playing card or postcard, and a coin.
[0:00 – 0:30] Introduction
"Good morning! I'm [Your Name], and I teach physics. In this short demo, I'll be taking a Class 9 CBSE lesson on Newton's First Law of Motion, from the chapter Force and Laws of Motion."
[0:30 – 1:15] Hook
"Let's begin with something all of you have experienced.
You are standing in a bus. The driver suddenly starts the bus. What happens to you?
(pause)
Yes, you fall backwards. And when the driver suddenly applies the brakes?
(pause)
Exactly. You fall forwards.
But here's the interesting question. Nobody pushed you. So why did your body move? Let's find out today."
[1:15 – 2:15] Demonstration
"Watch this carefully. I have a glass, and on top of it, a card. On the card, I've placed a coin.
What do you think will happen if I flick the card away quickly? Will the coin fly away with the card, or will it fall into the glass?
(pause)
Some of you might say it will fly away with the card. Let's check.
(Flick the card sharply. The coin drops into the glass.)
The coin dropped straight into the glass! The card moved, but the coin did not want to move with it. It stayed where it was, and then gravity pulled it down."
[2:15 – 3:30] Explanation
(Write on the board as you speak.)
"This tendency of an object to stay as it is has a name. We call it inertia.
Newton described it in his First Law of Motion:
An object remains in its state of rest or of uniform motion in a straight line unless an external, unbalanced force acts on it.
Let's break it down into two parts.
Part one: An object at rest stays at rest. That's our coin. It was at rest, so it 'wanted' to stay at rest even when the card was pulled away.
Part two: An object in motion keeps moving. That's you in the bus when the brakes are applied. The bus stops, but your body was moving forward, so it keeps going forward.
Now, back to our first question. When the bus starts suddenly, your feet move forward with the bus, because they are in contact with the floor. But the upper part of your body is still at rest, and it tends to stay at rest. That is why you fall backwards.
One more thing: the more mass an object has, the more inertia it has. That's why it is harder to push a heavy almirah than an empty chair."
[3:30 – 4:30] Check for understanding
"Now it's your turn. Think about this:
When you shake a branch of a mango tree, some mangoes fall down. Why?
(pause)
Take a moment… Yes! When the branch moves suddenly, the mangoes tend to stay at rest because of inertia. The connection to the branch breaks, and they fall.
One more quick one: why should we always wear a seatbelt in a car?
(pause)
Because if the car stops suddenly, our body continues moving forward due to inertia. The seatbelt provides the external force that stops us safely."
[4:30 – 5:00] Wrap-up
"So today we learned:
• Objects resist changes to their state of rest or motion. This is called inertia.
• Newton's First Law tells us that an object will not change its state unless an unbalanced force acts on it.
• More mass means more inertia.
For homework, find three examples of inertia from your home or your journey to school.
In our next class, we'll find out how to measure the force needed to change an object's motion — that's Newton's Second Law. Thank you!"
Tip: Practise the coin-and-card trick a few times before recording. A quick, sharp, horizontal flick works best.
