Look at the way the height of the blue columns changes on different birthdays. The highest column means the windiest weather, so which birthday gave most trouble in keeping the nest still?
Were there any birthdays when the amount of wind was exactly the same?
Which birthday had the least wind?
Was it more windy when Hawk was nine or when he was six?
Can you now choose a question to ask about this graph?
Repeat the same exercise with the following graph of mean daily temperatures at Manteo.
Hawk's birthday this year will be very special. He shares it with the 100th birthday of powered flight which began when Orville and Wilbur Wright first flew their airplane at Kill Devil Falls in North Carolina, very close to the places where Kitty and Hawk live now.
We would like you to tell us what you think the weather will be like at 10:35AM on December 17 this year?
There will be a big party in North Carolina and maybe you would like to have a party in your school on the same day!
The story above helps to set the scene for this classroom activity.
Present the graph so that it can be viewed at the same time by all students. Discuss the presentation then ask each student to pose a question, based on the graph, to the others. Watch the resulting questions range from the simplest to the most complex. From
Which birthday was the warmest? (simple)
Which birthday was colder than Hawk's fifth but warmer than his ninth?
The type of weather is also important to the way we enjoy being ouside. The four most common types are: clear, cloudy, rain, or snow. Kitty made four pictures, or symbols, to use instead of the words and they look like this for the last four years:
Make a game in which some small teams have only the text version of conditions and others have only the symbol version. As they question each other, see how well each teams does in recognizing words and correlating symbols. Finally, ask for predictions about the weather for Hawk's birthday this year, when he is ten.
To show Kitty's treasured data in its full glory we must include her more precise decimal values on each y axis and the actual years of recording on the x axis Her complete tables and graphs are as follows:
