In this lesson, students learned to interpret and analyze temperature and rainfall graphs, understanding that average monthly temperatures are represented by a line graph, while precipitation, including rain, snow, hail, sleet, and dew, is depicted by a bar graph. The mean daily temperature is calculated by averaging the daily minimum and maximum temperatures, using the formula: (Daily Maximum + Daily Minimum) / 2. Practical exercises included determining the mean temperature from given data, highlighting the importance of accurately performing these calculations for climate analysis.
