In the main menu of the Sandbox AR App, there is a Made By DE section.  This holds ready-made sandboxes for you to explore.

A ready-made Sandbox can still be edited and saved as though it were your own creation.

Loading from a QR Code

You can also open ready-made sandboxes using a QR code.

To do this, tap on Load from QR in the top righ-hand corner of the screen.  This will open a QR scanner.

Some Discovery Education lessons and resources contain a QR code to load a Sandbox.

You can also use this feature to scan a QR code generated by another Sandbox user.
