This instrument is a Six's maximum-minimum thermometer, used to record the highest and lowest temperatures reached over a period. Step 1: Identify the instrument. The diagram shows a U-shaped thermometer containing alcohol and mercury, with two metal indices. This is a Six's maximum-minimum thermometer. Step 2: Read the minimum temperature. The minimum temperature is indicated by the bottom of the metal index on the left (alcohol) side. The scale on the left increases downwards. The index is at 22^ (two divisions above 20^). Step 3: Read the maximum temperature. The maximum temperature is indicated by the bottom of the metal index on the right (mercury) side. The scale on the right increases upwards. The index is at 27^ (two divisions above 25^). Step 4: Read the current temperature. The current temperature is indicated by the level of the mercury column. Both sides of the mercury column should show the same current temperature. The mercury level on both the left and right sides is at 20^. Name of the instrument: Six's maximum-minimum thermometer* Minimum temperature: 22^ Maximum temperature: 27^ Current temperature (W): 20^ 3 done, 2 left today. You're making progress.
