An AskERIC Lesson Plan
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 669 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?
May 19940These lesson plans are the result of the work of the teachers who have attended the Columbia Education Center's Summer Workshop. CEC is a consortium of teacher from 14 western states dedicated to improving the quality of education in the rural, western, United States, and particularly the quality of math and science Education. CEC uses Big Sky Telegraph as the hub of their telecommunications network that allows the participating teachers to stay in contact with their trainers and peers that they have met at the Workshops.
