Students I worked with on Module 3 included: ______________________________________________________

SCORING

5 points-all elements labeled and found in the diagram (1 point for each item found)

5 points-correct building height (1 point deducted for every 2 feet in error)

MODULE FOUR-Using an Angle of Elevation to Predict the Time of Day (15 Points)

Materials Needed: Protractor, shadow, sunset & sunrise times, calculator (or trig. tables), pencil

Find the angle of elevation of the sun using any object’s height and the length of the shadow the object is

casting. You will not need to look into the sun for this and please don’t! Draw a picture showing your

measurements. Show your work as to how you found your angle of elevation.

What was the date and the exact time of the measurements taken? __________ on ___________

The sunrise time is _____. The sunset time is _____. (Use the Old Farmer’s Almanac Web Page)

Determine the time of day by using the sunrise and sunset times and your angle of elevation. SHOW YOUR

WORK!!!

Using this information, develop a formula to approximate the time of day.

Students I worked with on Module 4 included: ______________________________________________________

SCORING

6 points-correct drawing (2 points) with labels of the measurements found (2 points) and correct angle of elevation

with work (2 points)

3 points-approximate time of day found with appropriate calculations

3 points-correct method of finding the approximate time of day using simple trigonometry
