Bars compare categories. A line can connect one subject’s observations over time. A scatter graph shows paired numerical values for separate subjects. Do not join its points as a time story. Give each graph a title, labelled axes and even scales. Safety: Paper only; no seeds, apps or downloads. Stop: End after graph/key checks; do not claim real plant observations.

Materials: Paper, ruler and pencil; Four large paper scraps 1. Copy invented seedling records onto scraps: A, 2 cm tall, 2 leaves; B, 4 cm, 2 leaves; C, 6 cm, 4 leaves; D, 8 cm, 4 leaves; all on day 3. Separately record A’s heights: day 0, 1 cm; day 1, 1 cm; day 2, 2 cm; day 3, 2 cm. 2. Make a table ID | Day-3 height (cm) | Day-3 leaf count. Draw leaf-count bars: horizontal axis Seedling ID A–D; vertical axis Number of leaves 0–4 in equal one-leaf steps. Add a title. 3. Line graph: A’s height over time. Label horizontal axis Day, 0–3 in steps of 1; vertical axis Height (cm), 0–2 in steps of 1. Plot four time records and join in day order. Add a title. 4. Scatter graph: the four seedlings. Label horizontal axis Day-3 height (cm), 0–8 in steps of 2; vertical axis Day-3 leaf count, 0–4 in steps of 1. Plot paired values without joining; add a title. 5. Draw C schematically: one stem, four leaves, height label 6 cm; mark not to scale. Use this key: Four leaves? Yes → 6 cm tall? Yes C, no D. No → 2 cm tall? Yes A, no B. Test B. This key applies only to A–D. 6. Check points against the records. Which graph shows A’s growth from day 1 to day 2? Explain why the supplied patterns cannot establish a growth cause. Done: The table, three labelled graphs, schematic and tested key agree with the records. Proof: Keep all work. Note supplied data, adult axis help and unfinished components. Stop: End after graph/key checks; do not claim real plant observations.
