Computer Programming Language 💻

🎯 What We'll Learn Today

In this exciting lesson, you will:

• 🧠 Discover what computer programming languages are
• 👩‍💻 Meet Grace Hopper, a real-life coding superhero
• 🐛 Learn about bugs and debugging (hint: it involves a real bug!)
• 🎮 Set up your very own Scratch account
• 🚀 Start creating your first Scratch project

Do you know what is Computer Programming Language? 🤔

Instructions written by humans for computers to understand!

Imagine trying to talk to someone who only understands 0s and 1s - that would be super hard, right? 😅 That's exactly what early programmers had to do!

ℹ️ Info Fun Fact! Binary code is the fundamental language of computers, consisting of only two digits: 0 and 1. It looks like this: 01001000 01101001! (That's "Hi" in binary!)

While computers are designed to process binary code efficiently, humans find it challenging to work directly with these sequences of zeros and ones. Can you imagine writing a whole game using just 0s and 1s? 🤯

This led to the amazing development of:

1. Assembly Language 📝 - A more readable representation of machine code
2. High-level Programming Languages 🌟 - Languages that use human-readable syntax (like English!)
3. Modern Programming Tools 🛠️ - Advanced tools that make coding even more accessible (like Scratch!)

💡 Did You Know?

This evolution shows how computer programming has bridged the gap between machine understanding and human thinking. It's like building a bridge between two different worlds! 🌉

Meet Your Coding Hero! 🦸‍♀️

Who is Grace Hopper?

Grace Hopper (1906-1992) was like a real-life superhero of computers! 💪 She was a brilliant computer scientist, mathematician, and even a U.S. Navy rear admiral who changed the world of programming forever

.

note Amazing Grace! 🌟 Her friends called her "Amazing Grace" because of all the incredible things she did!

Her super achievements include:

• 🔧 Developed the first compiler - A special tool that translates human-friendly code into computer language
• 💬 Created FLOW-MATIC - The first English-language data processing compiler (computers could finally understand English!)
• 🏆 Led the development of COBOL - Which became the most widely used business programming language
  2
• 🌈 Made programming easier - She believed programming should use English-like commands instead of confusing mathematical symbols

What is a Bug? 🐛

Here's a funny story! A "bug" in programming is when your code doesn't work properly - like when your game character walks backwards instead of forwards!

ℹ️ Info The First Real Bug! 🦋 The term became famous when Grace Hopper and her team found an ACTUAL moth (a real bug!) trapped inside their computer in 1945. They taped it in their notebook and wrote "First ACTUAL bug found"

. How cool is that?

What is Debug? 🔍

Debugging is like being a detective for your code! 🕵️‍♀️ When something goes wrong, you need to:

1. Find the problem - "Why isn't my sprite moving?"
2. Look for clues - Check your code blocks carefully
3. Fix the bug - Change the code that's causing trouble
4. Test it out - Make sure everything works perfectly now!

7. Code your sprite! 💻 - Make it come alive with code blocks!

💡 Challenge Yourself! 🌟

Try to complete all 7 tasks. Each one teaches you something new about Scratch!

🤓 Super Smart Questions - Do You Know...

What's the difference between a sprite and costumes? 🎭

• Sprite = Your character or object (like a cat, ball, or spaceship)
• Costumes = Different looks for your sprite (like the cat with eyes open or closed)

ℹ️ Info Think About It! 💭 It's like you're the sprite, and your different outfits are your costumes!

What's the difference between adjusting position in output vs. costumes? 📍

• Position in output = Where your sprite moves on the stage when your game runs
• Position in costumes = How you draw or place parts of your sprite in the costume editor

Oh no! I deleted something by mistake! How do I get it back? 😱

Don't panic! Here's your rescue plan:

1. Quick Fix: Press Ctrl+Z (or Cmd+Z on Mac) to undo! ⏪
2. Lost a sprite? Check the sprite library or upload your saved files 📁
3. Missing costumes? Look in the costume library or your saved pictures 🖼️
4. Code disappeared? Use the backpack feature to save important code blocks! 🎒

note Pro Tip! 💡 Always save your project regularly by clicking File -> Save Now. Better safe than sorry!
