Lesson 1.2: Computers Are Everywhere!

Now that you’re an expert computer detective, let’s dive deeper! In this lesson, we’ll investigate the secret behind how all computers “think” and work.

What You’ll Learn

By the end of today’s investigation, you will be able to:

Sort different computers into groups based on their jobs.
Explain the secret three-step process all computers use: Input → Processing → Output.
Point out the “inputs” and “outputs” for everyday devices.
Feel comfortable finding your way around a tablet or computer.

Our Investigation Plan

Let’s hear about your computer discoveries from the “Family Computer Hunt” you did at home!
We’ll add all your new finds to our giant class computer chart.
It’s a celebration of all the amazing and different computers you found!

The Secret of Input-Output (20 minutes)

We’ll uncover the “input-processing-output” secret with fun examples.
In small groups, you’ll become investigators, figuring out the inputs and outputs for different gadgets.
Get ready to be a human computer! We’ll do a fun activity where you act out the steps to process information.

Digital Explorer Time (15 minutes)

Time to get hands-on with the classroom tablets and computers!
We’ll practice turning them on and navigating the basics.
You’ll get to explore some cool, pre-loaded educational apps. The goal is to get comfortable, not to become an expert today!

New Tech Words to Master

Input: Any information you give to a computer (like clicking a mouse, typing on a keyboard, or speaking to a smart speaker).
Output: The way a computer gives you information back (like showing something on a screen, playing a sound, or printing a page).
Processing: The computer’s “brain” thinking about the input to create an output.
Interface: The screen and buttons you use to interact with a device.
Navigate: Finding your way around a website or a computer’s screen.
