In this post, you are going to learn a few amazing ScratchJr project ideas! Scratch Junior, an introductory programming language, is a fun and fantastic way to introduce young children (ages 3-7) to programming. This amazing platform allows young minds to create their own animated stories and games.

ScratchJr is a block-based programming language, where students pull blocks and arrange them to perform actions. Children can alter a character's appearance, add their own voices, and even add customized backgrounds by importing their own photographs. Before putting together the programming blocks to make their characters come to life! So today, we're going to take a look at some fun ScratchJr activities for kids.

What is the difference between Scratch and ScratchJr?

ScratchJr was inspired by the popular Scratch programming language. Scratch was designed for kids ages 8-16 years old. Meanwhile, ScratchJr was developed keeping younger children in mind. So that it helps enhance young children's cognitive, personal, social, and emotional development.

ScratchJr has a simpler interface

ScratchJr's interface is much simpler than that of Scratch to reduce the complexity to entry for young children. For example, the number of blocks used in ScratchJr is comparatively less than Scratch.

Different blocks

Instead of stacking block top to bottom, in ScratchJr blocks are stacked left to right. ScratchJr also has fewer types of blocks than Scratch coding, for example there are more operators and variables blocks in Scratch.

Sound effects

Only one “pop” sound is available to use in ScratchJr. However kids can record any sounds they want. Though the recording time is limited to a minute.

Broadcasts

ScratchJr has a limited number of broadcast blocks: up to six on each page. Instead of passing a message in the form of text, each broadcast block contains a letter indicating a color associated with its specific message.

Optimized for mobile

ScratchJr is optimized for mobile and tablet devices, as opposed to Scratch which is built for computers. The ability to touch the screen of an iPad or an Android tablet helps make ScratchJr more accessible, too.

Grid system

ScratchJr's stage is divided into a grid that is 20 x 15 squares in size. Unlike Scratch's stage, which uses regular pixels that are not broken into a grid.

Paint editor

In ScratchJr, there's a paint editor where kids can alter pre-existing sprite/backgrounds or draw something of their choice. This feature helps kids learn how to create and express themselves.

Pages/stage

In ScratchJr, pages are "scenes" that hold their own sprites, background, and broadcasts. And you can only have up to 4 pages per project. Whereas in Scratch, students can make many more backdrops.

How do you create a project on Scratch Jr?

ScratchJr was specifically designed for young minds. So the interface and instructions are quite simple. Today, we'll walk you through the SratchJr app.

Just download the ScratchJr app to your device. Launch the app. And click on the Home icon to start a new project.

That will take you to your My Projects page. Click on the little “ + “ icon to start a New Project.

Here's how to make a game on ScratchJr

When you start a project, the default ScratchJr sprite will appear. If you want to change this default sprite, just click and press on the sprite until an “x” appears. Click on that “x” to delete the sprite from the stage.

1. Choose your sprite.

Select a new sprite by pressing the “+” icon on the left side to open up the characters gallery.


2. Change the background.

Once you have the sprite of your choice up on the screen, change the background by clicking on the “landscape picture” icon on the top of the screen. This will bring up the background gallery.

Choose whichever background you want. And tap on the check icon on the right corner of the screen to set the background.

3. Add your character to the stage.

Select the character of your choice by tapping on them on the stage. You’ll see the image on the bottom left corner - to double-check that you have selected the right sprite.

4. Run the code.

Hit the yellow block (the triggering block) and select the flag icon, which is the start button for the code.

Now you can explore the other colored blocks to create your own script. These programming blocks are divided into these categories:

  • Triggering (yellow block): Starts the code and sends messages to other scripts.
  • Motion (blue block): Where to move a sprite, how long a sprite moves, and changes angles.
  • Looks (purple block): Controls visibility, appearance, and text output.
  • Sound (green block): Plays a predefined “pop” sound or a recorded sound.
  • Control (orange block): Repeats a certain part of the script with a specified number of times.
  • Endings (red block): Controls when and how to end the script.

Explore fun ScratchJr projects, and discover a quick way to learn how to do new things it!

1. Racing: ScratchJr project idea

Use 2 characters/sprites to move across the screen from left to right.

Challenge: Get the characters to move across the screen at different speeds.

Guiding questions:

  • Why do we use the green flag?
  • How can we make the characters move?
  • How do we join the blocks together?
  • What do the numbers below the blocks mean?
  • What does the end block do?
  • How can you use different speeds for different characters?

Tips:

  • Start your program with a yellow-colored flag block.
  • Use the speed block to set the speed of each character.
  • Make both the characters move forward from left to right according to grid almost 16 numbers.
  • Use disappear block to hide your character once it reaches another end.
  • Use the red color end block to finish your code.

Solution:



2. Size up and down: Scratch project for kids

In this ScratchJr project, make your character change size by clicking on it. One character should increase in size, and one character should decrease in size, when you click on it. Also, the character will come back to its original size when the green flag is clicked.

Challenge: Make your character change its size by clicking on it. And also return your character back to its original size by clicking on the green flag.


Guiding questions:

  • How can you make your character change its size?
  • How can you start a project by clicking on the character?
  • How can you bring my character back into its original size?

Tips:

  • Start your program with yellow-colored START on tap block
  • Make your character increases or decreases by adding the shrink or grow block from the looks category.
  • Use another yellow-colored flag block.
  • Reset the size by putting the reset size block from purple blocks.

Solution:
