💡 Topic Summary
In Grade 4 computer science, understanding how to collect data in Scratch is a foundational skill. Data collection is simply gathering information that your program can use. Think of it like your game remembering things! The most common way to do this in Scratch is by using variables. A variable is like a special container that can hold a piece of information, such as a player's score, a timer, or even the number of times an event happens. These values can change as your program runs.
Scratch also uses sensing blocks to collect data directly from the user or the environment, such as asking for a name, detecting if a key is pressed, or if two sprites are touching. By using variables and sensing blocks together, you can create dynamic and responsive projects that react to user input and game events, making your Scratch creations much more engaging!
🧠 Part A: Vocabulary
Match the term to its correct definition by drawing a line or writing the letter next to the number.

- 2. Data
- 3. Collect
- 4. Scratch
- 5. Sensing Block
Definitions:
- 📦 A container in Scratch that can hold different values, like a score or a timer, and can change during the program.
- 📊 Information or facts that your computer program can gather and use.
- 🧺 To gather or bring together information.
- 🐱 A programming language where you drag and drop blocks to make animations and games.
- 👁️ A special block in Scratch that helps your program 'see' things like if a key is pressed or if two sprites are touching.
✍️ Part B: Fill in the Blanks
Complete the following paragraph by choosing the best word from the list below. Each word is used only once.
In Scratch, we can use a special container called a _______ to store information. When we gather this information, we are performing _______ collection. Blocks like the 'ask and wait' block are great for _______ data from the user. This helps make our games and stories more _______.
- 🗂️ variable
- 📈 data
- 🔍 collecting
- 🎮 interactive
🤔 Part C: Critical Thinking
Imagine you are making a Scratch game where a character collects stars. How would you use a variable to keep track of the player's score? Describe the steps you would take in Scratch to make this work.
