short, is a type of technology that allows machines to learn and make decisions like humans do. It's like having a robot brain that can think and solve problems on its own! • For example, is self-driving cars, which use AI to navigate and avoid obstacles. Pretty cool, right? 5 Scratch Tutorial for kids by Doaa Mohey
tool introduces machine learning by providing hands-on experiences for training machine learning systems and building with them. • Scratch-based Artificial Intelligence is considered a type of technology that allows machines to learn and make decisions like humans do. It's like having a robot brain that can think and solve problems on its own! 6 Scratch Tutorial for kids by Doaa Mohey
works by using algorithms to analyze data and make decisions based on that analysis. One way that AI can be used is through machine learning, where the system is trained on large amounts of data to recognize patterns and make predictions. • Scratch AI can be used is through natural language processing, which involves teaching computers to understand human language. This can be used for tasks such as a language translation or speech recognition. 7 Scratch Tutorial for kids by Doaa Mohey
• Scratch coding is defined as the process of writing and running programs using Scratch, a free programming language and code editor that helps young learners understand coding logic using blocks and visual aids. This article defines the concept of Scratch coding and its uses in computer science and programming. • Scratch AI project for kids can create using Scratch is a virtual pet. Kids can use different blocks in Scratch to program their pet to perform certain actions, such as playing fetch or responding to their name. Scratch Tutorial for kids by Doaa Mohey 11

what is machine learning? • What is Scratch-based machine learning? • How does machine learning work? • Creating a machine learning model in scratch. • Testing and improving your model. • conclusion 18 Scratch Tutorial for kids by Doaa Mohey
learning systems and creating things with them, this tool introduces machine learning. • It offers a simple-to-use guided environment for developing machine learning models for text, numeric, or image recognition. • By integrating these models into Scratch (a popular educational coding platform), this expands on current initiatives to introduce and teach coding to kids. • This will enable kids to construct projects and develop games using the machine learning models. Scratch Tutorial for kids by Doaa Mohey 19
a branch of artificial intelligence (AI) and computer science which focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy. • Machine learning is a type of computer program that helps computers learn from data, just like how you learn from your experiences. Imagine you're trying to teach a computer how to recognize different types of animals. 20 Scratch Tutorial for kids by Doaa Mohey
when computers learn how to do things without being specifically programmed to do them. It's like teaching a robot to think for itself! • For example of machine learning (ML), ML is teaching a computer how to play a game. Just like how you get better at a game the more you play it, a computer can use machine learning to improve its performance. • Example, the computer would then use this information to try and recognize new animals it hasn't seen before! 21 Scratch Tutorial for kids by Doaa Mohey
learning model in Scratch, we first need to gather data. This can be done by collecting information from sensors or by manually inputting data into the program. • Next, we need to train the model using algorithms that allow it to recognize patterns and make predictions based on the data we've collected. We can then test the model and make adjustments as needed to improve its accuracy. • For example, a machine learning algorithm cloud be trained on a dataset of cat images to recognize when a new image contains a cat. 22 Scratch Tutorial for kids by Doaa Mohey
Motion blocks (Blue): control the movement of a sprite (character or object) on the stage. For example, you can use motion blocks to make a sprite move in a certain direction or go to a specific position. 2. Looks blocks (Purple): change the appearance of a sprite, such as by changing its costume or size. 3. Sound blocks (Pink): play sounds or music in your program. 4. Events blocks (Yellow): set up events that trigger your program to run, such as when the green flag is clicked or when a certain key is pressed. 5. Control blocks (Tangerine): control the flow of your program, such as by repeating a section of code or stopping the program. 6. Sensing blocks (Teal): create programs that respond to input from the user or the environment. For example, you can use sensing blocks to check if the mouse is clicked or if a sprite is touching another sprite. 7. Operator blocks (Green): perform mathematical operations or compare values in your program. 8. Variables blocks (Orange): create variables (named values that can change) in your program and use them to store and manipulate data. Scratch Tutorial for kids by Doaa Mohey 30

For training machine learning models to recognize text, numbers, photos, or sounds, it offers a simple, supervised environment. Machine learning is pervasive. Everyday tools like spam filters, recommendation engines, language translators, chatbots and digital assistants, search engines, and fraud detection systems are all examples of machine learning systems that we all use. Machine learning systems will soon be commonplace in driving our automobiles and assisting medical professionals in the diagnosis and treatment of our illnesses. The program is fully web- based and may be used without any installation or complicated setup. It has an admin page that teachers or group leaders may use to monitor and administer access for their students. It was created for usage in the classroom by schools and volunteer-run coding groups for kids. It is being built by Dale Lane using APIs from IBM Watson.
33 Pre-trained models Kids can employ pre-trained models in their assignments. These sophisticated models make projects possible that would otherwise be too difficult for students to complete on their own and offer practical insights into some of the other capabilities of machine learning.

your machine learning model, it's time to test and improve it. Testing is essential for ensuring that your model is accurate and reliable. • One way to test your model is to use a validation set, which is a subset of your training data that is used to evaluate the performance of your model. You can also use metrics such as precision, recall, and F1 score to measure the accuracy of your model. • To improve your model, you can try adjusting various parameters, such as the learning rate, batch size, and number of epochs. • The experiment has different types of algorithms and architectures to see which ones work best for your particular problem. Additionally, you can try using techniques such as regularization and dropout to prevent overfitting and improve generalization. 34 Scratch Tutorial for kids by Doaa Mohey
a powerful tool that can help us make predictions and decisions based on data. We've seen how it works through the process of data collection, training, and prediction.
