SCIENCE FIELD STUDY — PLANNING AND RECORD SHEET
Version: 2026-09-11
Guide: https://yenra.com/mobile-data-acquisition/

Purpose: preserve enough context to compare field measurements fairly.
Use the equipment's instructions and your school's fieldwork procedures.
This sheet supplies a recording framework, not instrument acceptance limits.

Question / intended comparison:
Date / team / responsible teacher or investigator:
Site codes and location-record method:
Access permission / appropriate handling of location or personal information:
Quantity measured / units / fixed depth or height:
Independent sampling unit (for example, a distinct plot):
Number of independent plots or pairs / repeat visits:
How sites or pairs were selected:
Variables held constant / remaining differences between sites:
Collection order / plan to avoid confusing site effects with time changes:

EQUIPMENT AND PILOT
Sensor model / ID / range / accuracy specification and its conditions:
Device and app / software version:
Power / storage / offline collection check:
Clock, timezone and timestamp check:
Response-time or stabilization rule and supporting instructions:
Sensor comparison or reference check / readings / acceptance rule:
Calibration record, if applicable (a comparison check is not calibration):
Pilot export opened successfully / units and timestamps retained:
File naming / raw-data location / backup location:

FIELD RECORD — copy a row for each observation
Plot or pair ID | condition | date/time/timezone | sensor ID |
depth/height and units | reading and units | stabilization | notes

Record weather, shade, ground cover, setup changes and unusual events.
Preserve raw readings; record any exclusion and its reason separately.
Readings repeated at one plot do not create additional independent plots.

FICTIONAL WORKED EXAMPLE (soil temperature at a fixed depth)
Paired sun-minus-shade differences: 3, 4 and 2 degrees Celsius.
Mean of the three paired differences = (3 + 4 + 2) / 3 = 3 degrees Celsius.
These invented data represent three pairs on one visit. Repeated readings
can assess stability at a plot; broader claims require broader sampling.

ANALYSIS AND INTERPRETATION
Pair definitions / calculation with units:
Number of independent pairs and visits:
Variation across pairs / sensor uncertainty:
Missing observations / exclusions / reasons:
Other explanations or uncontrolled differences:
Conclusion limited to the sampled conditions:
Next visit or comparison needed:
