Line up your students' chairs 2-3 in a row with an aisle in between. They should resemble the cabin of an airplane. Pretend to be the flight attendant and tell your students how to be safe on an airplane. Explain to them that they cannot move around when the seatbelt sign is turned on because the ride may be bumpy and they could hurt someone. Also, talk about how airplanes are specially made so that we can breathe like normal even when we are high up in the air.
Bring in a model airplane to pass around to the students. Let them hold it and see it so that they feel more involved in the activity. Name the parts of the airplane with the students. Many of your students will have never been in an airplane before, so it is important that you give them a chance to learn the parts of the plane and get to experience it like the other students.
