📚 Topic Summary
In computer science, a program is like a set of instructions that tells the computer what to do. These instructions are often represented visually using blocks, especially in introductory programming environments. The "green flag" is often the starting point – it's the signal that tells the computer to begin executing the code. An 'event block' is triggered by a specific action, like pressing a key or clicking the mouse. In this activity, you'll be acting out these blocks, making you a real-life computer!
