**Course Title:** Introduction to Programming with Scratch **Section Title:** Introduction to Lists and Data Structures in Scratch **Topic:** Develop a project that uses lists to track and display information, such as a leaderboard or inventory.(Lab topic) **Objective:** In this lab, you will learn how to apply lists in Scratch to create a project that tracks and displays information, such as a leaderboard or inventory. By the end of this lab, you will be able to create a project that demonstrates the practical use of lists in Scratch. **Project Overview:** One of the most common uses of lists in Scratch is to track and display information, such as scores, high scores, or inventory items. In this lab, you will develop a project that uses a list to store and display information. You can choose to create either a leaderboard or an inventory management system. **Step 1: Planning Your Project** Before you start coding, take a moment to plan your project. Think about what information you want to track and display. What kind of data will you be storing? How will you organize your list? Make sure to write down your ideas and think critically about how you will implement them. **Step 2: Creating a List** To create a list in Scratch, you will need to use the "Make a list" block under the "Data" category. This block allows you to create a new list and name it. For example, if you are creating a leaderboard, you might name your list "High Scores." Once you have created a list, you can add items to it using the "Add to List" block. This block allows you to add a new item to the end of the list. You can also use the "Insert at List" block to insert a new item at a specific position in the list. **Step 3: Populating Your List** Once you have created a list and added items to it, you will need to populate the list with data. You can use variables to store data and then add that data to the list. For example, if you are creating a leaderboard, you might use a variable to store a player's score and then add that score to the list. **Step 4: Displaying Your List** To display your list, you can use a "List" block under the "Data" category. This block allows you to display the contents of the list on the screen. You can also use the "Item of List" block to display a specific item from the list. **Lab Exercise:** Your task is to create a project that uses a list to track and display information. You can choose to create either a leaderboard or an inventory management system. **Leaderboard Project:** Create a project that allows players to input their scores and stores those scores in a list. The list should be displayed on the screen, and the player with the highest score should be displayed first. **Inventory Management System Project:** Create a project that allows players to input items they want to add to their inventory. The items should be stored in a list, and the list should be displayed on the screen. Players should be able to remove items from the list as well. **Tips and Resources:** * [Scratch Documentation on Lists](https://en.scratch-wiki.info/wiki/List_(data_type)) * [Scratch Discussion Forums](https://scratch.mit.edu/discuss/) **What to Do Next:** Once you have completed this lab, you can move on to the next topic: "Common issues in Scratch projects and how to identify them." from the section titled "Debugging and Troubleshooting Scratch Projects." **Leave a Comment or Ask for Help:** If you have any questions or need help with this lab, leave a comment below.
