## Objectives

• The students will apply observation and inference skills.
• Introduce students to collecting and recording data with a pictograph.

## Materials

• Large month-long calendar.
• Cut outs of weather symbols (from set provided, glued to cardboard and protected with clear contact paper).
• Large sheets of paper for two graphs.
• 8 x 10 sheets of paper for each child to make paper airplane.
• Rubber cement or two sided tape.

## Teacher Background Information

Make the weather symbols and a large calendar. Make two large graphs. One should have the number of days up the left side and five columns across for Rainy, Snowy, Sunny, Cloudy and Windy. The second should have the number of days up the left side and two columns for "Flying Today" and "No Flying Today" across.

Too rainy, too windy and too snowy days are the days most small plane pilots do not fly. Your students will be basing their decisions on paper airplanes, but thats not too far different from the small plane without the fancy instrumentation of the larger ones.

## Procedure

• Help the children make simple paper airplanes.
• Let them fly their planes inside when they are done.
• Put up the calendar and graphs and explain that you will be charting the weather and deciding each day whether its a good day to fly the paper airplanes outside.
• "What have you noticed about the weather today?"
• "What did you notice yesterday?" "Similarities?" "Differences?"
• "What could happen outside that would make it a good day to fly?"
• "A bad day to fly?"
• Show children symbols for the weather conditions and explain that the class will decide on one of them for each day.
• Before afternoon recess, have students make the decision about the kind of weather.
• Put the symbol on the calendar with rubber cement (on one side only, so you can pull it off easily) or two sided tape
• Have a student color the appropriate square on the first graph.
• Decide, given the weather conditions, if it would be a good day to fly their planes.
• Talk about WHY they think so.
• Color appropriate square on second chart.
• Encourage students to fly their planes on good days.
• At end of month, tally the different weather days and the flying and no flying days and discuss the overall conditions for the month.
