Field worksheet

Observation & Experiment Record

Document what you actually saw. Separate direct observation from inference. Never claim a result is decisive when multiple models predict the same outcome — the worksheet will flag that for you.

Question being tested *

Competing prediction A *

Competing prediction B

Location

Date & time (local + UTC)

Equipment (make, model, calibration)

Procedure (step by step)

Environmental conditions (weather, refraction, seeing, etc.)

Raw measurements (numbers you actually recorded)

Calculations (show your work)

Potential errors and their magnitudes

Result (what you observed, not what it means) *

Does this distinguish the two predictions?

Independent replication

If it distinguishes, why? (Show which prediction it rules out)

This worksheet is a personal record. To submit for review, use the Community Science lane — reviewers may request raw files and independent replication before any result is treated as evidence.
