This chart is used to predict what the weather will be for the week and compare it to the actual weather. Predictions can either be student driven or look at www.weather.com and record what they predicted. Throughout the week, check www.weather.com daily and record the actual weather for that day or record weather from the day before. Predictions can then be changed or modified. This is great to use over a 2-4 week period to see patterns in weather.
