Measure:
Distance between markers =
Distance from #1 to base of tower =
Distance from #2 to base of tower =
5. Collect marker #2, but leave marker #1 where it lies.
Task Set 2: Solving Triangles
Id like you to collect a series of three sets of measurements, from dierent parts of the eld. The
rst should be near the tower; the second should be an intermediate distance away; the third should
be farther away.
Series A
Stand near the light tower, but not too near. Aim for an angle of inclination between 60 and 75 .
Drop marker #2 at your feet. Measure:
Angle of inclination:
Distance from #2 to base of tower = Series B
Stand farther from the light tower. Aim for an angle of inclination between 35 and 55 . Drop
marker #2 at your feet. Measure:
Angle of inclination:
Distance from #2 to base of tower =
Series C
Stand still farther from the light tower. Aim for an angle of inclination between 20 and 35 . Drop
marker #2 at your feet. Measure:
Angle of inclination:
Distance from #2 to base of tower =
Collect marker #2, but leave marker #1 where it lies.
Task Set 3: Extrapolated Direct Measurement
The light towers are reinforced with zig-zagging metal beams. Find a
repeating structural unit. Describe it, such as zig zag zig zag for a
unit with four diagonal beams, as pictured at right.
Description:
Height of structural unit:
Number of structural units in tower:
How far is marker #1 from the shadow of the top of the tower?
Distance =
Collect all your materials. Youve nished the Park component.
How could you use the information you collected to compute the height of the light tower? There
are ve independent calculations you can do to nd it (one from Set 1, three from Set 2, one from
Set 3). Perform these calculations on a separate piece of paper and attach it to this worksheet.
Which one(s) do you trust the most? How might you explain any discrepancies?
