Big ideas start with a little play. Guide a robot, create colorful pixel art, and discover how your favorite gadgets connect.
Computer Builder Lab
Give the robot a complete computer! Start with a case, add the parts inside, and connect a monitor, keyboard, and mouse. Tap a part and then its matching spot, or drag a part into place with a mouse.
The case holds and protects the computer’s internal parts.
In this virtual build, the robot handles the small cables for you. Select a part, then tap a labeled spot. No timer—take your time!

Internet Safety Detective
Follow the robot through three simple steps. It shows you exactly what to tap, explains the clues, and helps you choose a safe action. There is no timer.
- 1. Read and checkRead Your situation first. Then tap each highlighted message card.
- 2. Pick a safe actionPress Continue, then choose what you would do.
- 3. Read the lessonSee why your choice helps. Press Next case to play again.
All messages, links, and files here are pretend. Nothing opens or downloads.
What is the safest next step?
Find the clues, then choose your next step.
Step 3 · Here is why
You paused, checked the clues, and made thoughtful choices. That is detective power!
Your detective rule: Pause before clicking. Keep personal information private. When unsure—or if you already clicked—tell a trusted adult. You can always ask for help.
Robot Coding Maze
Our robot needs a recharge! Add instructions, then run your program to reach the battery. Turn commands rotate the robot; Forward moves one square in the direction it faces.
Green arrow = robot and direction · yellow battery = goal · blue blocks = walls
Build your program
Plan a path. Try a few steps, then add more instructions if the robot needs another try.
Robot Memory Match
Our robot has hidden some favorite things! Turn over two tiles and see if their pictures match. Remember where each picture lives and find all the pairs.
Tap a tile, or use Tab and Enter on your keyboard. Matching pictures stay open. Different pictures turn back over. Take your time—there is no timer!
Spot the Difference: Robot Lab
Two robot labs look almost the same. Look for changed colors, missing parts, or extra shapes. Tap a difference in either picture to mark it in both!
Take your time—there is no timer. Use Tab and Enter to check objects with a keyboard. A green circle means you found a difference.
Robot Power-Up Challenge
Can you fill the robot’s battery before 15 seconds are up? Tap the big power button with one finger. The clock starts with your first tap!
Use one finger, a mouse, or press Enter or Space while the power button is focused. Scroll outside the button.

Binary Robot Decoder
The world of computing runs on ones and zeros! Computers represent information using tiny choices called bits. A bit can be 0 or 1. Patterns of bits can represent numbers, letters, pictures, sounds, and instructions.
Think of bits as tiny light switches
In this game, 0 means off and 1 means on. Each switch has a number above it. Add the numbers above the switches that are on to find the total. This way of writing numbers is called binary.
0101 means 4 + 1 = 5.
From right to left, each switch is worth twice as much: 1, 2, 4, 8… Four bits can make numbers from 0 to 15. Eight bits can make 0 to 255. Eight bits together are called a byte.
Explore the switches
Tap the switches and watch the number change. Try making 5 using 4 and 1!
Read left to right. On a small screen with two rows, read the top row first.
A secret about letters
Bits can stand for letters too. For example, the capital letter A is 01000001 in ASCII, a code for characters. Those eight bits make 65, and ASCII uses 65 for A. The code tells the computer how to understand the bits!
Bit-to-Byte Data Builder
One tiny bit is just the beginning! Pack small units into bigger ones and help the robot climb the data ladder—from bits and bytes all the way to yottabytes.
First, meet the building blocks
A bit is one 0 or 1. 8 bits make 1 byte. A byte can hold 256 different bit patterns. Bigger units help us describe how much data a file or device can hold.
The everyday scale: 1,000 bytes = 1 kilobyte (kB). Then 1,000 kilobytes = 1 megabyte (MB), and the same pattern continues.
The binary scale: some computer tools group data in 1,024s. The precise names are kibibyte (KiB), mebibyte (MiB), and gibibyte (GiB). A kB and a KiB are different amounts. In either scale, a byte always has 8 bits.
Build 1 byte
8 bits make 1 byte.
Big names, tiny beginnings
Byte → kilobyte → megabyte → gigabyte → terabyte → petabyte → exabyte → zettabyte → yottabyte.
These units measure amounts of data. Time is separate: bits per second measure how quickly data moves. Watch the letters too—b means bit and B means byte.
Pixel Art Studio
Choose a color, then tap or drag across the squares. Draw a robot, a spaceship, or something nobody has imagined yet!
Drag to draw. Scroll using the space outside the drawing grid.
Your art supplies
Your picture downloads as a PNG. It stays on your device; it is not posted to a gallery.
Cable Match
Match the pictured cable shape to the right port. Devices can use different connectors, so look at the shape instead of guessing from the device alone.
Keyboard Playground
A roomy place to learn your letters before writing a story. On a phone or tablet, tap the practice box to open your keyboard.
Big keys, little discoveries
Explore one letter at a time. Tap the big keys below, or use your keyboard in the practice box. There is no timer or score here.
Typing Quest
Ready for a story? Copy the words below at your own pace. Go slowly, fix mistakes with Backspace, and build confidence. On phones and tablets, tap the typing box to open your keyboard.
Choose your practice style
Take your time with a story, or try a gentle timed challenge when you feel ready.
Blue highlights show matching characters. Underlined red characters need another look. Spaces and punctuation count too. Speed is only a practice estimate; careful typing matters more than rushing. One word is counted as five matching characters.
Built for curious minds. These activities need no account and do not upload drawings or game progress. An adult can help with instructions. Real cables should only be connected with permission, and never forced into a port. Explore the main Tech Tools.
