  1. 15°C · The liquid column ends at 15 on a Celsius thermometer. Priya should record 15°C.
  2. Rain gauge · A rain gauge collects rain. Its marked rainfall scale shows how much rain fell, usually in millimeters.
  3. True · True. An anemometer measures wind speed. On a cup anemometer, faster wind makes the cups spin faster.
  4. 4 · The number above Tuesday's bar is 4. The class recorded 4 mm of rain.
  5. Wind vane · A wind vane's arrow points toward the direction the wind comes from.
  6. 6 May, 3 p.m.; 19°C; 3 mm; wind from west · Keep 19 with °C, 3 with mm, and the wind direction as from west. The date and time belong in the same diary row.
  7. Add all daily rainfall readings into a total for each month · Add the daily rainfall readings for each month and compare the totals. The larger total means more rain fell.
  8. 16°C, using 2°C for each space · Each space is 2°C. Three spaces above 10°C reach 12°C, 14°C, then 16°C. Record 16°C.
