Select a checkpoint to chart and graph for one week. Then check the weather for that checkpoint each day using the weather links below. Make note of the high and low temperatures on your chart. Plot those points on your graph. Be sure to use a different color pencil for high and low. That way you won't confuse them.
Once you have plotted the points for several days you can begin to connect the points to each other using a straightedge or ruler to get a straight line. Be sure that your graph has the following; a title, horizontal label, vertical label, key, a carefully selected scale and appropriate intervals.
Here is a tip - while the vertical scale on many graphs starts at 0, you might want to start yours in negative numbers (perhaps -40 degrees Celsius) depending on the actual temperature. Below is a sample of what your chart and graph might look like:
Bonus Question: How would meteorologists use this type of data to predict changes in temperature?
