Over the last 500 years humans have gone from seeing a man in the moon to seeing a man on the moon. This phenomenal advance in collective learning has taken place thanks in large part to a group of strategies which have come to be referred to as The Scientific Method. If humankind has made so much progress by using the Scientific Method, then why not teach all our children to use it at an early age rather than waiting until high school or college to teach a few who are fast-tracked into science and technology careers. If we have made this much progress with a few humans using these strategies, then what will our collective learning curve look like if we are all trained to make science discoveries and/or to appreciate the discoveries of others?

HOW CAN WE MEASURE DIRECTION?

OBJECTIVE: CONSTRUCT AN AZIMUTH CHART

Time Needed: One period

Materials: Protractor, pencil, paper

Procedure:

1. Make a dot in the middle of your paper.
2. Place the center mark of the protractor over the dot on the paper.
3. Mark the two zero points on either side.
4. Use the bottom edge of the protractor to draw a line that connects the two zero marks and the center.
5. Place the protractor so that it lines up with the center and zero marks.
6. Draw the hemisphere arc that connects the two zero points. Mark the 90 degree point.
7. Flip the protractor upside down.
8. Line up the center and the zero points.
9. Draw another hemisphere arc. Mark the 90 degree point.
10. Draw a line that connects the two 90 degree points and passes through the center.
11. Mark off every ten degrees between the zero marks and the 90 degree marks.
12. Label the four cardinal points: North, South East, West.
13. Label the Azimuth numbers for the cardinal points.
North – 0/360 degrees
East - 90 degrees
South – 180 degrees
West - 270 degrees
14. Label every ten degrees between the cardinal points.
