Coral Guard
You're the Coral Guard! Protect the reef by programming IF/ELSE rules — decisions that check what's true and choose what to do. IF a fish is a friend → welcome it! ELSE → warn it away! Every computer decision starts with IF!

⚡ Today's Concept: Conditionals (IF / ELSE)

An IF/ELSE statement is how computers make decisions. You give it a condition — a TRUE/FALSE check — and it does one thing IF true, and a different thing ELSE (if false). It's like a fork in the road: IF the path is clear → walk straight. ELSE (if blocked) → take a detour! Every app, game, and website uses IF/ELSE to make choices!

🤔 Condition — a TRUE/FALSE question ✅ IF true — do this action ❌ ELSE — do that action instead
← Last time you learned BOOLEAN LOGIC (TRUE/FALSE). Now you'll use those TRUE/FALSE checks to make IF/ELSE decisions — the most powerful tool in every program!
Step 1 / 4
A friendly fish approaches! Set the rule: IF creature is friendly → Wave. ELSE → Hide. Then press the check button!

You're a Coral Guard!
You programmed IF/ELSE rules for every creature — the reef is safe thanks to your decision-making code! 🐠✨

💫 What You Learned

  • IF/ELSE is how computers make decisions — check a condition, then choose the right action.
  • The condition is a TRUE/FALSE question. IF it's true, run the first action. ELSE run the other.
  • You can change conditions and actions to create different rules for different situations.
  • Every program uses conditionals — games, apps, websites — they all make IF/ELSE choices!
  • Boolean logic (TRUE/FALSE) powers every IF check. You already learned that — now you used it!
🎬 Come Back Tomorrow!
Next up: combine IF/ELSE with loops to build a creature counter that checks every visitor automatically!
