In this task, you'll use spreadsheet software to analyze and graph the average temperatures measured on Earth for the past 136 years. You'll then use your data and graph to determine what's happening to the global
temperature over time.
Estimated time to complete: 1.5 hours
You'll need these materials:
• computer with Internet access
• graphing software such as Microsoft Excel or Google Sheets
Part A
Begin by reflecting on what you already know about global temperature trends. What trends do you
expect to see as you plot how temperatures have changed over time? What are your sources of prior
knowledge, and would you consider them reliable?

explanation:

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
