📚 Topic Summary
An 'unplugged activity' in computer science means learning concepts without using a computer. Making a Peanut Butter & Jelly (PB&J) sandwich is a fun way to learn about sequencing, which is the order in which steps must be performed to achieve a specific outcome. In computer programming, the order of commands is crucial; messing up the sequence can lead to unexpected or incorrect results. Just like in code, if you spread the peanut butter *before* opening the jar, you're going to have a sticky mess! This activity helps visualize how algorithms work.
Think of each step in making the sandwich as a line of code. The sequence of those 'code lines' must be accurate for the program (or sandwich!) to work correctly. This hands-on example simplifies complex programming logic, making it easier to grasp foundational concepts.
🧮 Part A: Vocabulary

✏️ Part B: Fill in the Blanks
Complete the paragraph using the words: sequence, algorithm, steps, outcome, order.
An ______________ is like a recipe that tells you the exact ______________ to follow to achieve a specific ______________. The ______________ is crucial; the ______________ of actions will determine if your result is as expected.
🤔 Part C: Critical Thinking
Imagine you're writing instructions for a robot to make a PB&J. What are some things you might need to be *extra* specific about to avoid any hilarious (or disastrous!) mishaps?
