a finished AI Collector Game presented out loud

Teacher demo

Today is short. Show the room one thing — the entire demo — front to back, in under 90 seconds:

  1. Open your project. Both tabs ready.
  2. Say sentence 1 of the demo script. Click the green flag.
  3. Play one short round. Talk over it (sentences 2 and 3).
  4. After the round ends, say sentences 4, 5, and 6.
  5. Step back. Smile.

That's the whole demo. 90 seconds. No more. The kids should see it once before they do it.

The big idea​

For five days you built something. Today is the hour where someone who has never seen it gets to watch.

   Build the game     (Days 1–4)
   Polish the game    (Stage 9)
   Show the game      ← today

There are no new blocks today. No new code. No new sprites. The game is already done. This final hour is about presentation — making sure both tabs are open, your AI is loaded, your script is memorized, and your laptop is positioned where parents can see.

You'll use the demo script you wrote yesterday. Six sentences. They will carry you through the entire demo, even if something glitches mid-game. Confidence comes from preparation — not from being unsurprised. Pros call this rehearsal for a reason.

Before you start

Your Stage 9 game should be bug-fixed. Your demo script should be filled in. You should be able to play a full round without anything weird happening.

Build it​

Step 1 — Open both tabs and confirm the AI loads​

This is the single most important check of the morning.

  1. Click the Teachable Machine button at the top of this page. Confirm your project still loads. The camera should turn on.
  2. Click the RAISE Playground button. Open your saved project from Stage 9.
  3. Click the green flag once. Make any hand sign. Confirm the game responds.

If anything fails here, flag a coach immediately. Don't wait. There is time to fix one thing before parents arrive — but only if you flag it now.

Step 2 — Practice the demo from memory​

Open your demo script on paper. Read it once, silently.

Now put the paper face-down. Look at your laptop screen. Recite all six sentences out loud, looking at the screen the whole time.

Here is the script template again — yours should be filled in:

1. My game is called __________________________.
2. I trained my AI to recognize ______________________.
3. My AI controls __________________________.
4. The hardest part was __________________________.
5. My favorite part was __________________________.
6. Now I will show you my game.

If you stumble, look at the paper, fix the sentence, and try again. Three full run-throughs from memory should feel comfortable.

Step 3 — Time yourself doing the whole demo​

Set a timer for 90 seconds. Start it.

Do the whole thing — script + game — in one go:

  • Sentences 1–3 (about 20 seconds): introduce the game and the AI.
  • Sentence 6 ("Now I will show you my game"): click the green flag.
  • One round of gameplay (about 30 seconds): play, narrate as needed.
  • Sentences 4–5 (about 20 seconds): the hardest part, your favorite part.
  • Step back and smile.

If you ran past 90 seconds, find the slow part and shorten it. If you finished under 60 seconds, you went too fast — slow down sentence 2 (the AI training one).

Step 4 — Set up the laptop for the demo​

Where will you stand? Where will your parent stand?

  • Position the laptop so the camera has a clear view of your hand. (Sit straight in front of it.)
  • Position the screen so someone over your shoulder can see it. You may need to tilt it.
  • Plug in the charger. A dead laptop mid-demo is the worst kind of failure.
  • Make sure the volume is up so they can hear your catch sound and win sound.

Step 5 — The actual demo​

When your parent arrives at your station:

  1. Take a breath.
  2. Say sentence 1.
  3. Walk through your script, click the green flag, play a round.
  4. Finish with sentences 4–6 and "Now I will show you my game" (wait — you already said that one as the cue to play).

You did it. The hour we've been working toward all week just happened. Smile.

Understand it​

Everything you needed for today, you already did yesterday. The game works. The script is written. The model is trained. Today is not a coding day — it's a showing day. The biggest mistake on demo day is trying to add one more feature instead of practicing what's already there.

A demo script sounds like a tiny thing, but it carries a huge load. If your AI glitches mid-demo, the parent doesn't know what was supposed to happen. You do. The script keeps you talking and re-routing — "...and the AI is reading my hand right now, see how the sprite moves..." — even when something behind the scenes is broken. Words bridge what's missing.

The 90-second target matters because attention is short. A 30-second demo feels rushed. A 3-minute demo feels indulgent. Ninety seconds is enough to show the magic — AI training + game built — and short enough that the parent's smile is still fresh at the end.

Confidence is built, not granted. It comes from the rehearsals you did yesterday. The reason you're not nervous (much) is that you've done this five times already today. Real engineers, scientists, and artists all rehearse before they present. You just learned that.

Try this​

Learning beat

Try this

Three short experiments. Predict before you run, then test your guess.

Predict first

Predict: out of the six sentences in your script, which one will get the biggest reaction from your parent? Sentence 2 (the AI training)? Sentence 4 (the hardest part)? Mark your guess. After your demo, check if you were right.

Compare

Try the demo once silently — just the game, no script. Now do it again with the full script. Which version is more demonstrably impressive? The script does more work than you'd think.

Connect

Look back across all 10 stages. Pick the stage where the biggest thing clicked for you. Tell your parent about that stage in sentence 5 (the favorite part). The most memorable moment of your week is also the most memorable thing for them.

Test your finished demo​

  • Both tabs (Teachable Machine + RAISE Playground) are open.
  • You clicked the green flag once and confirmed the AI responds.
  • You said all six demo sentences out loud from memory.
  • You did a full 90-second run-through and stayed under time.
  • Your laptop charger is plugged in.
  • Your volume is on.
  • Design check. Imagine your parent has never seen Teachable Machine or RAISE Playground. After your 90-second demo, can they explain (in one sentence) what your game does? If yes, your demo works.

If it breaks (during the demo)​

This is the real demo-day playbook. Things will go wrong. Keep talking. Fix calmly.

  • My game doesn't start when I click the green flag. Don't panic. Say "give me one second — let me reload" and use the demo script to introduce the AI while it loads. Refresh the RAISE tab if needed.
  • The AI doesn't recognize my hand mid-demo. Move closer to the camera. Adjust the lighting. If it still fails, say "sometimes the AI needs a moment — that's part of working with real machine learning" — that's true, and it sounds confident.
  • The catch sound plays 10 times. Don't acknowledge it. Keep playing. The parent will laugh once and forget by the end.
  • The game crashes mid-round. Say "that's a bug I found in playtest — let me reset" and click green flag again. Bugs in demos are normal.
  • A parent asks a question I don't know. Say "good question — let me show you the part that does that" and open your code. Parents love seeing the code. The answer often shows itself.
  • I forget my demo script entirely. Just play the game and narrate what's happening. "My hand makes the sprite move. The score goes up when I catch the star. I trained the AI from scratch this week." Three sentences is enough.

The thing nobody tells you: parents don't expect a perfect product. They want to see that their kid built something this week. The game running is enough. Talking about it with confidence is the rest.

Coach notes

This is the most emotional stage of the week. Some campers will be over-the-moon excited. Some will be quietly anxious. Both are normal at ages 7–9. Walk the room ten minutes before parents arrive and check in with the quiet ones — a small encouragement ("I watched your demo run, it works great") goes a long way.

The single biggest risk on demo morning: a model URL that no longer loads. Have a coach do a sweep at the start of this hour and confirm every camper's green flag triggers a working AI. If one is broken, re-export from Teachable Machine before parents arrive.

When parents are circulating, your job as a coach is to be invisible. Don't translate for the camper. Don't finish their sentences. Let them stumble through their script. The parent is here to see their kid speak — not a polished presentation. Quiet support beats running commentary every time.

If a demo fails completely (model won't load, RAISE crashes), have the camper show the screenshot or screen-recording backup from Stage 9's hard stretch. Always have a backup.

After the parent leaves the camper's station, give a quick fist-bump or "that was great". Five days of work landed today. The camper needs to feel that the work was seen.
