PBS1282 · Friday September 11 · Original John Hay practice

Documentation practice

Measure a paper scene and check what five photo examples can show.

Open your D05 evidence sheet, Case A

Complete the whole D05 evidence sheet. Use this supplement for B1, B2 and the sketch and photo records. Do not copy the older sample measurements or photo answers. Keep the existing B3 calculation and A, C, D and E tasks.

PLAN-1 reference

This practice area is 200 cm wide and 160 cm long. RP1 and RP2 are fixed reference points. All four points are north of their connecting line. Each grid step represents 20 cm. These dimensions describe this simulation only.

PLAN-1 dimensioned training area. The rectangle is 200 centimeters east to west and 160 centimeters south to north. RP1 is its southwest corner and RP2 its southeast corner. 200 cm in the training area160 cmRP1 (0, 0)RP2 (200, 0)RP1 to RP2 = 200 cmN P1P2P3P4

Scale

1 cm on paper represents 20 cm in the training area.

Example:
100 cm ÷ 20 = 5 cm on paper.

At actual-size printing, the rectangle is 10 cm wide and 8 cm tall. Screen size varies.

Help with the plan and the numbers

RP means reference point: a fixed place you measure from. RP1 is the southwest corner, at (0, 0). RP2 is the southeast corner, at (200, 0). Each position gives centimeters east, then north, of RP1. Distances are rounded to 0.1 cm. These are supplied simulation values, not measurements from a photograph.

PLAN-1 · B1 and your measured sketch

Your sketch and four measurements

  1. Use the blank frame below or draw a 10 cm by 8 cm frame on paper.
  2. Keep the north arrow and both reference points. Add P1 to P4 using the reference plan.
  3. Copy the supplied RP1 and RP2 distances into your record. Use them to plot and check your sketch; these are simulated values, not measurements you collected.
  4. Complete the four rows below. On D05 B1, write “See PLAN-1 page”. Do not make a second copy.

Print at 100% or Actual size. Check the rectangle with a ruler before using it as a scale drawing. If it is not 10 cm by 8 cm, draw your own frame at that size.

PHOTO-1 and PHOTO-2 · Your section scene

Compare the framing

A frame is the part of an image shown. These are training views, not five recovered photographs from a previous case. A digital crop does not move the camera.

PHOTO-1 · Complete studio overview

Simulated studio scene with a console, cabinet, blanket and numbered markers.SIMULATED
Source: Case A scene illustration, a01.png. Purpose: show the relationships between visible objects. What cannot be measured from this overview?

PHOTO-2 · Digital detail crop of PHOTO-1

Digital detail crop of PHOTO-1, centered on the numbered cabinet and blanket area.SIMULATED
Source: the same scene image, cropped for a framing exercise. No object was changed. Purpose: show an item in relation to its surroundings. Is enough context visible? Name an additional view that would help.

PHOTO-3 to PHOTO-5 · Shared illustrations

Check identification and scale

For C1, use your own Case A image and case records. PLAN-1 and these shared illustrations add no case facts. A reddish-brown mark does not identify a substance.

PHOTO-3 · Digital crop

Digital crop centered on a reddish-brown mark on a rough surface.SIMULATED
Source: scene-scale illustration, cropped. Purpose: establish the mark's size and item identity. Which needed features can you see?

PHOTO-4 · Backpack

Illustrative backpack in a hallway with a blank tent card, L-shaped ruler and measuring tape.SIMULATED
Source: D05 parallel illustration, unchanged. Purpose: connect the frame to a numbered record. Is the item identified? Do not infer movement from this one view.

PHOTO-5 · Complete scale illustration

Simulated reddish-brown mark beside an L-shaped scale and marker numbered 1.SIMULATED
Source: scene-scale illustration, unchanged. Purpose: support a size measurement. Compare it with PHOTO-3. What else would you need before giving a numerical size?
Photo vocabulary and viewing help

Overview: a wide view. Detail: a smaller area. Scale: a measurement reference beside an item. Item identifier: a label connecting an image to a record. A ruler's presence alone does not make a measurement reliable.

This original John Hay practice supports observation and documentation skills connected to PLTW. It does not record completion of a separate official PLTW activity.

Five photo records · Include once in your D05 packet

Record and judge each frame

Use the source captions on pages 3 and 4. Write “not visible” or “not supplied” when needed. Never make up a photographer, time, camera direction or original item position.
