Event Focus

Imagine teaching about engineering and scientific practices by engaging your students in real scientific research. Do your students struggle with identifying the IV and DV in experiments?

Description

Teachers will learn how to engage students in the investigation of variables that affect flight patterns of paper aircraft. Students manipulate wing shape to evaluate the affect on flight patterns. Students launch paper aircraft in the classroom to collect, measure, and evaluate data. All materials needed to implement the lesson will be created during the workshop.

When implementing the activity with your students, the students will

• use algebra to calculate wing area, wingspan,

chord length, and aspect ratio;

• use a portable glider catapult to analyze wing

geometry based on measurement (distance rating)

and observations (glide rating and speed rating);

• design, construct, and test an experimental wing to

achieve maximum distance;

• incorporate collaborative problem-solving

strategies in a real-life application.

Vocabulary:

Aspect ratio - Wingspan length divided by the average chord length.

Chord - Straight line distance joining the leading and trailing edge of an airfoil.

Fuselage - The part of the airplane to which the tail and wings are attached. The fuselage holds passengers and cargo and is streamlined to produce the least possible drag.

Horizontal stabilizer - The horizontal part of the tail.The horizontal stabilizer helps to increase the stability of the aircraft.

Lift - A force that is perpendicular to the air flow around the aircraft.

Thrust - A force created by the engines that pushes an aircraft through the air.

Weight - The force of gravity acting on an object. The weight force pulls an aircraft toward the Earth and must be overcome by a combination of lift and thrust.

Wingspan - Distance from wing tip to wing tip.

Reynolds number - When testing a small scale plane or flying object inside a wind tunnel, the Reynolds number helps aerospace engineers adjust the wind tunnel test conditions to make sure results of the wind tunnel match the full scale model in flight. Engineers sometimes use a gas other than air (for example nitrogen, carbon dioxide), increase air density by pumping the wind tunnel up, adjust temperature, and run the tunnel at different speeds so the Reynolds number in the wind tunnel matches flight conditions.

Instructional Objectives

Engage |
Learners will observe flight patterns. |

Explore |
Learners will explore various wing dynamics, and discuss observations and possibilities for differences in flight patters observed. |

Explain |
Learners will develop and test hypothesis, identifying the IV, DV and other components of scientific practices. |

Elaborate |
Learners will identify another hypothesis that could be developed and tested using the practices listed above. |

Evaluate |
Learners will evaluate data collected, and form a conclusion. |
