## Complete activity

X04 — Soil display for busy visitors, two 15-minute sessions. Materials: complete Day44/F3, three big headings, paper flaps or AAC. Make Plant, Habitat and Water doors. Explain two source-supported roles with one specimen-level unknown each. Put the full source card beside the doors so a visitor can check it. A possible ordinary habitat door says soil can be habitat but our sketch names no organism. Do not promise drinking-water safety or plant growth from the general role. Invite a visitor question or self-check whether your source and actual observation are distinct. Keep the product for a later source update rather than requiring field collection.
