Use scratch to remix a program

What can I use instead of a microphone or if I can't log into a Scratch account?

If you don't have a microphone, choose a sound from the Sounds library or upload a sound file in the Sounds tab, and if you can't log in use Scratch Desktop or click Create to work locally (you won't be able to press Remix or share online).

My Remix button is grayed out or the new sound doesn't play when I test—what should I check?

Make sure you're logged into Scratch and pressed Remix to make an editable copy, then in the sprite's script replace the 'play sound' block with the exact name of your new sound from the Sounds tab and add a 'when green flag clicked' event so the script actually runs when testing.

How can I adapt this remix activity for different age groups?

For younger kids (5–7) focus on deleting/adding a sprite and changing a costume or sound and then clicking the green flag, for elementary (8–10) add one simple code change or an event block, and for older kids (11+) have them record custom sounds, create multiple costumes for animation, and add variables or extra scripts before sharing.

What are easy ways to extend or personalize the remix beyond the basic steps?

Personalize by painting or uploading a custom sprite and backdrop, record several new sounds in the Sounds tab and attach them to different 'play sound' blocks, add a score variable or extra event blocks to change behavior, and then include a project description before sharing on DIY.org.
