Look first, then use a tool to check a detail. Describe colour, edge, shape, size and pattern. An observation such as a jagged edge is not the same as a guess about the plant’s name. We need not name the species today. Safety: Do not collect unknown plants, insects or mould. Use the hand lens indoors away from direct sunlight; do not taste or smell samples. Stop: End after one checked clue. Stop if the lens or sample is damaged; never point a lens toward the sun.

Materials: Two clean adult-approved leaves or two textured cloth samples; Hand lens, if already available; otherwise a ruler with millimetre marks; Paper and pencil 1. Set the two samples on paper and label them A and B. Draw each outline from direct observation before using the tool. 2. If using a hand lens, move it slowly between your eye and each sample until the detail is clear. If using a ruler, align zero with one end and measure the sample’s longest length in centimetres. 3. Create a table headed Feature | A | B. Complete colour, edge or surface, pattern and size. Use the tool for at least one recorded detail. Write not measured rather than guessing a length. 4. Add one enlarged detail drawing, with a line pointing to the feature actually seen. Say one similarity and one difference supported by the table. 5. Give the adult an identification clue, such as Choose the sample with the straight edge. Have them choose A or B, then check the actual sample. Done: Two samples have specific descriptions, one tool-supported detail and one checked comparison. Proof: Keep the table, outline and detail drawing. Record which tool was used and any adult measuring help. Stop: End after one checked clue. Stop if the lens or sample is damaged; never point a lens toward the sun.
