Effective Presentations
What separates a forgettable talk from one people actually remember.
What we'll cover
Learning Objectives
- Understand what makes a presentation effective or ineffective
- Learn slide design principles that support — not replace — speaking
- Practice good speaking habits: eye contact, pacing, clarity
- Identify common mistakes presenters make
- Design and deliver a short, well-structured mini presentation
Let's start with a story
The Presentation That Put Everyone to Sleep
A speaker reads every word off the slide, in a flat voice, for ten minutes straight. The slide has twelve bullet points in size-8 font. By the end, no one remembers a single thing.
Discuss: What did this presenter do wrong? How many mistakes can the class identify?
The core idea
Slides Support — They Don't Replace You
A slide deck is a visual aid, not a script. The presenter is the star. Slides exist to help the audience understand — not to do the talking for you.
Wrong mindset: "My slides tell the whole story so I don't have to say much."
Right mindset: "My slides help my audience follow what I'm saying."
The three pillars
What Makes Presentations Work
1Clear Slides
Simple, visual, focused
2Strong Delivery
Voice, eye contact, pace
3Audience Awareness
Who are they? What do they need?
Slide design
The 6×6 Rule (and Why to Break It)
A common guideline: no more than 6 bullet points per slide, 6 words per bullet. But even better — replace bullets with visuals, diagrams, or one big idea per slide whenever possible.
- One main idea per slide
- Large, readable font (minimum 24pt)
- Use images and diagrams, not walls of text
- High contrast: dark background + light text, or vice versa
Slide design: compare
Bad Slide vs. Good Slide
❌ Bad
Photosynthesis
• Photosynthesis is the process by which plants use sunlight
• Plants absorb carbon dioxide through their leaves
• Water is absorbed through the roots
• Chlorophyll is what makes plants green
• The plant produces glucose and oxygen as outputs
[Font size: 9pt]
✅ Good
Photosynthesis
☀️ Sunlight + 💧 Water + CO₂
↓
🍃 Glucose + O₂
Presenter explains the details out loud
Delivery skills
How You Speak Matters As Much As the Slides
Eye Contact
Look at different people in the room — not the screen, not the floor, not your notes constantly.
Voice Pace
Slow down. Most nervous speakers rush. Pause after key points to let them sink in.
Volume
Speak clearly and loudly enough for the whole room. Not shouting — projecting.
Body Language
Stand confidently. Avoid fidgeting, crossing arms, or turning your back to the audience.
Structure
Every Good Presentation Has a Shape
①Hook
Grab attention in the first 30 seconds
②Body
2–4 key points, clearly explained
③Close
Summary + memorable ending
A strong opening hooks the audience. The body delivers information clearly. A strong close makes it stick.
Common mistake
The Wall of Text Slide
A student pastes their entire essay onto a slide and reads it word-for-word during their presentation. The audience stops listening within 20 seconds.
Why it fails: The audience reads faster than you speak. If everything is on the slide, they've finished reading and are now bored while you're still talking.
Common mistakes
Presentation Mistakes to Avoid
- 🚫 Reading directly from the slides
- 🚫 Too much text on each slide
- 🚫 Distracting animations and sound effects
- 🚫 Font too small to read from the back of the room
- 🚫 Skipping practice — then stumbling on your own slides
- 🚫 Ending with "that's it" instead of a real conclusion
Think about it
Class Analysis: Spot the Mistake
Here is a list of presentation behaviors. Vote: good habit ✅ or bad habit ❌?
- Making eye contact with the whole room
- Reading every bullet point off the slide
- Having 15 slides of text for a 3-minute talk
- Using one large image with a short caption
- Speaking very fast to "get it over with"
- Pausing for 2 seconds after an important point

Hooks
How to Start Strong
The first 30 seconds decide whether your audience pays attention. Great openers include:
- A surprising fact: "Did you know 65% of people would rather go to the dentist than do public speaking?"
- A question: "What if your phone disappeared for a week — could you survive?"
- A short story or scenario
- A striking image
Closing strong
How to End Well
A weak ending destroys a great presentation. Avoid:
❌ Weak
"That's basically it... um... yeah. Any questions?"
✅ Strong
"So to summarize: great presentations are simple, visual, and practiced. The next time you watch a presenter — look for these three things. Thank you."
Class discussion
What Presentations Do You Remember?
Think of any time you've watched a presentation — a teacher, a YouTube video, a TED Talk, even a student presentation.
Discuss: What made it memorable? Was it the content, the visuals, the speaker's energy, or something else?
Class activity
30-Second Pitch Challenge
Each student (or pair) has 30 seconds to "pitch" a topic — no slides. Just speaking. The class evaluates: clear? engaging? structured?
Topics to choose from: Why their favorite game is great · Why school lunch should be improved · Why we should/shouldn't have homework · A skill they know
Mini project
Build a 4-Slide Presentation
Design a short 4-slide deck on any topic you choose, applying today's principles.
1Hook slide
2Key point #1
3Key point #2
4Strong close
Rule: No more than 10 words per slide. The rest must be delivered by speaking.

One Thing You'll Do Differently
Think about a presentation you've given before — a class project, a reading aloud, anything.
Reflect: Name one specific thing you would do differently next time, based on what we learned today. Share with a partner, then with the class.
Before you go
Today We Learned...
- Slides support your speaking — they are not a script
- Good design: one idea per slide, large font, visuals over text
- Strong delivery: eye contact, clear voice, confident pace
- Every presentation needs: a hook, a body, and a strong close
- Practice is the single most important factor in a confident delivery
Well done, Grade 6! This is the final chapter of the year. You've covered online safety, logic, Scratch, AI, and now presentation skills — a full toolkit for the digital world.
