If the students were able to look at pictures of older planes in the pre activity, have them note if they see any at the airport. Remind them to look for similarities and differences of this airport to bigger airports. Have students make paper airplanes and measure how far they fly using the meter stick. Make a list of things about this airport. Use a Venn Diagram for the comparing and contrasting of the little and big airports.
Students can make a class book about the uses of big and little airports.
Discuss with the class the importance of aircraft and the changes in the airplanes. Students could illustrate what they saw on the field trip and put into a class booklet. Many of these activities could be used for visiting Montgomery County Airpark and Dulles International Airport.
