Writing Lab Reports earth Science Online Each lab report should contain

Writing Lab Reports earth Science Online Each lab report should contain the following: I. Heading: This should be the name and number of the lab, the date, and your name. II. Purpose: A one or two sentence purpose in your own words. Do not copy mine.

III. Procedure: A one or two paragraph explanation of what went on in the lab exercise. I don’t want fine details—this is an overall view. IV. Data and/or Observations: Some labs will ask you to record numbers and/or make observations—these should be in your report. Many of the online labs do NOT ask you to do this—don’t make up stuff that isn’t called for. V. Sample calculations: If the lab procedure asks you to calculate something, show your work. VI. Results: If the lab procedure asks you to calculate something and/or make a decision (such as the type of mineral present), you should show these results. Again, many of the online labs do NOT ask you to do this. VII. Questions: This is probably the most important part of the report in that it shows me that you did the exercise and hopefully learned from it. You need to write the QUESTIONS as well as the ANSWERS. Please write your Answers using bold or italic letters - it will really help me grading VIII. Conclusion: A one sentence statement as to whether you achieved the purpose or not. Lab Reports should always include I, II, III, VII, and VIII. They may be submitted electronically by attaching them to the assignment box. They must be done with MS WORD. Lab # 6 (Summer)—Earth Science Weather Purpose: To keep a weather diary to check the accuracy of local forecasts for a given location. One of the forecasting tools used by weathermen is the historical record for a given location coupled with the type of weather approaching the region. Although general comments can be made such as “high pressure signals good weather†or “low pressure signals bad weatherâ€, the actual prediction depends on the location in question and the weather for the preceding days for that location. In this first of two weather labs, you will keep a “ weather diary †for a week which will reflect the predicted high temperature, low temperature, and weather conditions for a given location each day as well as the actual weather conditions for that same location. The data for this diary must come from an Internet source or a newspaper (most of the local TV stations have a website with weather information if you don’t like one of my suggestions below.) You must use the same source everyday and you should get the predicted weather the day BEFORE each entry date and the actual high and low temperatures the day AFTER each entry date.

If you are doing this for your home location (which I suggest), you can use what you observe outside in the blank labeled “Actual Weather†each day. Procedure: 1. Although this lab is for one full week’s worth of weather, it may take more days to compete the data record so plan ahead. You can start any day of the week that you want, but you need the forecast from the day before . 2. You can use the data sheet provided under the icon on the lab page of Blackboard or make up your own. However, the minimum amount of information for each day consists of the predicted high, low, and weather (from the day before) and the actual high, low, and weather (on the day following.) 3. Once you have gathered the data for all days, you should construct 3 line graphs as described below. a) Using the 7 days of the week as the horizontal axis and temperature as the vertical axis, plot the forecasted high temperatures as a line graph (connected dots.) On the same graph, plot the actual high temperatures as a line graph. Be sure to label completely. b) (New graph) Using the 7 days of the week as the horizontal axis and temperature as the vertical axis, plot the forecasted low temperatures as a line graph (connected dots.) On the same graph, plot the actual low temperatures as a line graph. Be sure to label completely. c) (New graph) Using the actual high and low temperatures for the 7 days, find the average temperature for each day. Using the 7 days of the week as the horizontal axis and temperature as the vertical axis, plot the average temperatures for the week. Be sure to label completely. Questions: 1. Compare the actual temperatures to the predicted temperatures for the first two graphs and discuss any trends observed. Explain your reasoning for each. 2. Looking at the third graph (average temperatures), do you see any trend for the week. Explain your reasoning. 3. Explain why this weather diary may or may not be useful for the same week next year. 4. Comparing the forecasted weather and the actual weather for the whole week, how would you rate the forecasting ability of the source you chose? Explain your reasoning. Suggested Weather Sites: The Weather Underground at At the top left corner, type in your zip code or the zip code that you will observe for the week and after the local forecast is loaded in Internet Explorer, save this as a Favorite. I like this site as it is easy to click on “Yesterday’s Official Weather†to get the actual readings from the day before. The Weather Channel at Near the top, type in your zip code or the zip code that you will observe for the week and after the local forecast is loaded in Internet Explorer, save this as a Favorite. To see the current forecast for the next day, scroll down. To see yesterday’s actual readings, click on “Yesterday†in the yellow bar near the top (you may have to choose a different town as all reference points don’t collect temperature data.) National Weather Service (NOAA) at When the opening screen loads, click on Arkansas on the U.S. map. (If you are not doing this diary for some place in the continental U.S., this site won’t work well.) On the next screen, look below the map and choose a town (or the nearest one to you) and the seven day forecast will come up. To see what happened yesterday, you click on 2-day history, but the information is very detailed and hard to read.

To accurately assess the reliability of weather forecasting methods, this report embarks on a systematic weather diary over one week for a specific location. The primary purpose is to compare the predicted weather conditions with actual observations to evaluate forecast accuracy and identify potential trends. This process not only reinforces understanding of weather patterns and forecasting skills but also offers insights into the practical utility of meteorological predictions for planning and decision-making.

The procedure involves collecting forecast data from a consistent online source or newspaper daily, ideally the same source throughout the week to maintain consistency. The forecast data should include predicted high and low temperatures along with weather conditions, recorded the day before each date. Following each day's actual weather—either from online sources or personal observation—the actual high and low temperatures and weather conditions are documented for the subsequent day. This process requires continuous daily data collection for at least a week, with the flexibility to extend the period if necessary to complete the data set.

Once data collection is complete, three key graphs are constructed for analysis. The first graph depicts forecasted versus actual high temperatures across the seven days, with properly labeled axes and data points. The second graph similarly compares forecasted and actual low temperatures over the same period. The third graph calculates the average daily temperature, combining the high and low values, and plots these averages over the week, providing a visual trend of temperature fluctuations.

To interpret the data, the report critically compares the forecasted and actual temperatures, discussing any noticeable differences or patterns. These include potential overestimations or underestimations in forecasts, consistency in temperature deviations, and the reliability of the forecast source. Analyzing the trend in the average temperature graph helps determine whether the week's weather showed stability, warming, cooling, or variability.

Additionally, the report considers the usefulness of such weather diaries for future reference, discussing their practicality for planning activities or assessing forecast accuracy in subsequent years. A comparative evaluation of the forecasting source encompasses assessing the closeness of predictions to actual weather, potential sources of errors, and overall reliability.

Finally, this study emphasizes the significance of accurate weather prediction in societal planning, agriculture, disaster management, and daily life activities. The findings highlight the strengths and limitations of current forecasting tools and stress the importance of continuous improvement in meteorological sciences to enhance forecast precision. Overall, this report demonstrates a comprehensive approach to understanding weather forecasting's accuracy and utility through systematic data collection, analysis, and critical evaluation.
