Lesson Goal
• Experience the practical applications of aerodynamics through a design process.
Objectiveso Identify the four forces on airplanes.o Compare inputs to the flight behaviors.o Understand and apply Newton’s laws of motion and
discover their practical applications in aerospace engineering.
o Design wings while considering certain limits and requirements.
o Build according to defined designs.o Improve designs and test new designs.o Determine the center of gravity.o Balance the weight distribution while building the
airplane.
ActivityThis lesson took three to four days
Day 1 :•Pre-assessment •Styrofoam plat experience•Concepts and new Vocabulary
Concepts & New Terms•Forces: Thrust, Drag, Lift, Weight•Physical Laws: Law of Motion & Applications•Dihedral: Upward angle of the wing which
increases the flight stability
Boeing 737
Harrier GR7
Wing Project OverviewDay 2 to 4:•Project Discussion•Importance of Design with examples•Why we need to consider stuff…•Building and assembling•Testing and modifying
Design Improvements•Center of Gravity•Balancing the airplane•Weight amount and distribution•Flight behaviors•Fins vs. wings
Launching the Airplanes

Reflections & ConclusionWent well Went not well
Improvements/ Recommendations
Activity
Very good helped the students understand dihedral and general
physical concepts NA
Let one student come to the front and explain it to the class
Project
Good needed some adjustments and modifications, Students learned about design inputs Material
Make sure to have enough material
Concepts Applications of Newton‘s laws
Students have problems with
directions, areas, scale and
measurements
Make sure that students have a
basic level of understanding
ReviewGood at the beginning and
summative at the endSometimes at the
end
Warm-ups and Formative
assessment
Time Activity was good
Need more time especially for IEP‘s,
explain concepts and Project
What’s next? •Wings and fins•Changing attributes•Obserevations•Engineering Applications•Three variables in one graph
