3. Train the Model

 Click "Train Model" (this takes a bit longer for audio)
 Wait for training to complete

4. Test Your Model

 Speak each command clearly into your microphone

 See if your model correctly identifies each command

 Ask family members to test it with their voices

What to Observe:

 Does your model work for voices other than yours?

 Does background noise affect accuracy?

 Are similar-sounding words ever confused?

Hands-On Activity: Plant Classification Model

Problem: Create an AI model that can identify three types of plants:
 Flowers  Trees  Shrubs

Steps to Follow:
1. Collect Images

 Take 20-30 photos of flowers (roses, daisies, sunflowers, etc.)

 Take 20-30 photos of trees (oak, pine, maple, etc.)
 Take 20-30 photos of shrubs (lavender, boxwood, holly, etc.)

 Try to vary the background and lighting in your photos.

2. Upload and Label
 Open Teachable Machine and start a new image project.

 Create three classes: "Flowers" "Trees" and "Shrubs"

 Upload your images to the appropriate classes.
3. Train the Model

 Click the "Train Model" button and wait 30-60 seconds.

 Your model is now learning to recognise different types of plants.
4. Test Your Model

 Find new plant images that your model hasn't seen before.

 Use your webcam or upload photos to see what your model predicts.

 Note whether it correctly identifies each type of plant.
