Submission guidelines

Acceptable activity formats

• A paper drawing or map of the five layers. A photo of that paper is enough later.
• A PDF, PNG, JPEG, or WebP of your own activity work, once upload exists.
• A short optional reflection. Long answers are not required.
• No computer is required to complete the activity.

Leave these out

• Do not upload passwords, secrets, or access tokens.
• Do not upload private school, medical, or financial records.
• Do not upload another person's image or voice without permission.
• Minors should avoid uploading identifying photos, audio, or video.

Showcase

Community showcase is moderated. Asking to be included is separate from submitting, and approval is not automatic. You can participate in private and never appear in the gallery.

Engineer / Researcher is an educational lane. It does not make the activity a research study.
