  1. Indirect Measurement By: Michelle Pomposello

  2. Purpose To determine the height of a part of the LAHS using indirect measuring methods.

  3. Theory Indirect Measurement: technique that uses proportions to find a measurement when direct measurement is not possible Example: Eratosthenes was the first person to accurately measure the diameter of the earth using a similar method that I used in my experiment.

  4. Experimental Technique Step 1: Measure the length of my shadow while standing at a certain position Step 2: Measure the length of the chosen point of the school within a quick amount of time to avoid the amount of error Step 3: Convert all of the units into meters Step 4: Use the H/B = h/b formula to solve for H (the height of the school)

  5. Diagrams 1.545 m 14.2 m 24.315 m 2.65 m

  6. Data & Analysis My height: 1.545 m My shadow height: 2.65 m School height: H School shadow height: 24.315 m

  7. Height Indirect Measurement: 14.2 meters Direct Measurement: 12.8 meters Accuracy: there was a difference of 1.4 meters between the 2 measurements To get the direct measurement, I measured the length of the long bricks, the short bricks, and the red bricks. Each brick had a different measurement so I counted the number of bricks in each category and multiplied that by each brick’s measurement. I then added the three measurements together to get the direct measurement of the fixed point of the building

  8. Conclusion In conclusion, by using my direct measurement and comparing it to my indirect measurement I found that my amount of error was only 1.4 meters off. The actual height of the building was 12.8 meters while my indirect measurement was 14.2 meters. Some factors that may have affected the measurement would be the timing between measurements of the shadows.
