TITLE:     FLYING OBJECTS

AUTHOR:   Daniel L. Ormond; Mary S. Black Elementary, NV

GRADE LEVEL/SUBJECT:     3rd on up     Science

OVERVIEW:
The students need a general background in measuring using metric
systems and have an awareness of types of flight formations of
boomerangs.

PURPOSE:
This activity is a culminating activity that provides an application
to measurement and to flying objects.

OBJECTIVE:
The students will measure, draw, and cut out a flying wheel out of a
six inch card.

RESOURCES/MATERIALS:
Compass, light weight cardboard, scissors, metric rulers,
protractor, and a book.

ACTIVITIES AND PROCEDURES:
1-  First of all the students need to have a six inch square of light
weight cardboard.

2-  Using a compass at 7 cm. the student will draw a circle. They
must keep the compass at 7 cm..  and mark off six equal arcs.

3-  Using a protractor mark off the 120 degree mark, and draw a
line.  You should have a shape that is a cross that resembles the
peace sign.  Then use a metric ruler and measure 1 cm. on each side
of the line.  Now the student will have a line that has 2 cm. thick.

4-  The students will then need to cut out the design.  It is their
paper boomerang.

5-  Place this on a book with an edge hanging over and flip it with
your finger and it will fly.  It actually flies and will return.

TYING IT ALL TOGETHER:
1-  Now have the students measure how far their boomerangs fly.

2-  Try flying them inside vs. outside.  This can be charted and the
results compared.

3-  Have the students write about if they were a boomerang, how
would it feel?
