AI Model Creation
Unlock Audio Lesson
Today, we're diving deep into creating our own AI models. Can anyone tell me why it's important to learn how to build models?
Is it because we can teach machines to learn from data?
Exactly! By training models, we understand the training and testing process, learning patterns from datasets. Remember the acronym 'TTP' which stands for Training, Testing, and Patterns!
What tools can we use for this?
Great question! We can use tools like Teachable Machine or Machine Learning for Kids that are designed for our level. What do you think we can create with these tools?
How about making an image classifier for pets?
That’s an excellent idea! Remember to collect your sample data and document your findings. Let’s summarize: understand TTP—Training, Taking data, and Finding Patterns!
Sustainable Development Goals (SDGs)
Unlock Audio Lesson
Now, let’s shift gears and discuss our next project which focuses on Sustainable Development Goals, or SDGs. Can anyone name some SDGs?
I know about reducing poverty and ensuring clean water!
And also climate action!
Perfect! These SDGs give us a framework for identifying problems. Let's think about how we can use AI to solve issues like pollution. Has anyone thought about using the 4Ws Problem Canvas?
What is the 4Ws canvas exactly?
The 4Ws canvas helps clarify our problem by answering Who, What, Where, and Why. For example, if we take air pollution, Who is affected? What is the problem? Where is it occurring? And Why does it concern us? Remember this framework as W^4!
That makes it easier to understand!
Exactly! Alright, let’s summarize: when approaching SDGs, use the 4Ws canvas—Who, What, Where, Why—our W^4 tool!
Data Collection and Visualization
Unlock Audio Lesson
Next, let's discuss data collection and visualization. Why is this step crucial in our projects?
It’s important to gather accurate data to support our AI models!
Absolutely! We can use spreadsheets to record our data. What types of visualizations can help us understand our findings?
Bar charts and pie charts help to see the differences clearly!
Yes, and we can use line graphs to show trends over time! Remember the mnemonic 'DRA'—Data, Representation, Analysis —to keep track of the data management process.
What if we spot a correlation?
Great question! Finding patterns means we can better tailor our AI solution. To summarize, think of 'DRA'—Data, Representation, Analysis—when handling your project data!

Students will build a basic AI model using user-friendly tools. This project helps students understand the training and testing process, concept of datasets, and how machines learn patterns.
Detailed Explanation
In this project, students are tasked with building a basic AI model. This involves using user-friendly tools designed for beginners, making the learning process engaging. The objective is to grasp several key aspects: first, understanding the idea of training a model—where you teach the AI using various examples. Secondly, you will learn about testing the model, which is how you check if the AI is working correctly. Third, you will explore the idea of datasets, which are collections of information the model learns from, and lastly, how machines learn patterns from the data provided to them.
Examples & Analogies
Imagine teaching a child to recognize different animals. You show them pictures of cats, dogs, and birds (this is your dataset). You first explain that a cat is a furry animal that says ‘meow.’ This is similar to the training process. Later, you show them a new picture and ask, ‘Is this a cat?’ and depending on their answers, you guide them until they learn to recognize cats correctly. The child represents the AI model learning from examples.

Tools to Use
1. Teachable Machine https://teachablemachine.withgoogle.com/ A web-based tool by Google that allows anyone to train a model using images, sounds, or poses.
2. Machine Learning for Kids https://machinelearningforkids.co.uk/ Designed especially for students to create and train models using text, images, or numbers and use them in Scratch or Python.
Detailed Explanation
Two specific tools are suggested for building AI models: Teachable Machine and Machine Learning for Kids. Teachable Machine is a simple web-based platform created by Google. It allows users to train AI models using various types of data, like images, sounds, or poses of people. The second tool, Machine Learning for Kids, is tailored for students, enabling them to create and train models that they can integrate into projects using Scratch (a visual programming language) or Python (a versatile programming language). These tools aim to simplify the concept of training AI, making it accessible and enjoyable for learners.
Examples & Analogies
Think of Teachable Machine like a customizable toy where you can train it to recognize your voice, claps, or even dance moves. Just like how you personalize a toy to respond to your own commands, Teachable Machine lets you teach it to recognize specific inputs and act on them—like identifying your favorite song when you clap or speak.
Steps to Build the AI Model

Steps to Perform
1. Choose a type of data (Images/Text/Sound).
2. Collect sample data for different classes.
3. Train the model using the tool.
4. Test and refine the model.
5. Present the output and share your learning.
Detailed Explanation
The process of building the AI model involves several systematic steps. First, you need to choose what type of data you will work with, which could be images, text, or sounds. Next, you collect sample data that you will use to train your model—like gathering pictures of different animals if you're building an image classifier. The third step is to use the chosen tool (Teachable Machine or Machine Learning for Kids) to train the model on your collected data. After training, it’s essential to test the model to see how well it performs, which may involve making adjustments to improve accuracy. Lastly, you will present your AI model and share what you learned during the process.
Examples & Analogies
Consider a cooking class where you decide to make pizza. First, you choose your ingredients (data type), like cheese, sauce, and toppings (sample data). Then, you gather everything you need (collect sample data). You follow a recipe to combine them (train the model) and bake it to see how it turns out (test the model). If it doesn’t taste right, you might tweak the recipe (refine the model). Finally, you proudly serve your pizza to others and explain your cooking journey (present your output and share learning).

Example Ideas
• Image Classifier: Recognize happy and sad faces.
• Sound Classifier: Differentiate claps, whistles, and snaps.
• Text Classifier: Identify positive or negative feedback.
Detailed Explanation
Here are some practical examples of projects students can undertake. For an image classifier, students can create a model that distinguishes between happy and sad facial expressions, helping them explore emotions visually. A sound classifier could be a model that identifies different sounds, such as claps, whistles, and snaps, which reinforces auditory recognition skills. Lastly, a text classifier could be developed to analyze feedback, determining whether comments are positive or negative, helping learn how machines can process and interpret human language.
Examples & Analogies
Imagine you have a pet dog. When it sees you smile, it wags its tail, but if you're sad, it may come close and nuzzle you. An image classifier doing something similar would recognize your happy face and respond appropriately. Similarly, if you clap and whistle to call it, it learns the difference between those sounds, much like how a sound classifier works.
