```Flight Angles Of InclinationMarie C. Smith                 Anthony Overton Elementary School                               221 E. 49th St.                               Chicago IL 60615                               (312) 535-1430Objectives:

The students will:
1.  Observe the flight of a glider.
2.  Measure the distance flown from a given point.
3.  Analyze the effect of a change of angle of inclination on the
launch/flight of sling launched gliders.
4.  Collect data on distance flown when glider is launched from two
different angle-ramps.
5.  Record and communicate test results to the class by use of a horizontal
bar chart for students to generalize conclusions from data.  The effect
of angles and comparison of their size/measure will be given by
students.

Materials needed:

Glider
Trundle wheel
Yard stick
Ramp
Airplane Flight Chart
Hinged Angle

Strategy:

1.  Explain that airplanes have engines and gliders do not.
2.  Use a chart to demonstrate angles of flight for airplanes.
3.  Demonstrate how to launch glider from ramp, use  trundle wheel and record
data.
4.  Divide the class into four groups.  Distribute a glider, trundle wheel,
yardstick, an angled ramp, and data collection sheet to each group.
5.  Proceed to a launch site (outside, weather permitting).
6.  Launch gliders, measure distance traveled, and record results.
7.  Students will assume the following roles:
Pilot-to launch glider from ramp
Navigator-uses trundle wheel to measure distance traveled
Air Traffic Controller- assist in location of straight line distance of
flight and checks trundle wheel reading
Flight Attendant- stabilizes ramp and records data.
8.  Each student assumes each role once and ramps should be exchanged by each
pair of groups.
9.  Return to class, discuss and analyze data using a pictograph.
