Observation — Science definition
Defined in 2 courses:
- A recorded detection or measurement under a stated method. (Science 6: Matter, Energy & Earth Systems)
- Information gathered through senses or instruments. (Earth & Space Science)
Where it is taught
- Scientific Inquiry: Questions, Evidence & Explanations — Inquiry, Measurement & Models, Science 6: Matter, Energy & Earth Systems, Grade 6
- Measurements, Models & Evidence — Investigating Earth, Earth & Space Science, Grade 9
In use
An observation nobody can deny, a list of possible causes, a test that could have come out either way, and a measurement at the end.

Questions using observation
Problem 1
- observation: A recorded detection or measurement under a stated method.
- A plausible explanation is automatically a directly observed fact.
- Every scientific investigation must follow exactly the same steps.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
observation: A recorded detection or measurement under a stated method.
A recorded detection or measurement under a stated method. The sunny tray lost 4 g more in the hour, but sunlight and surface area both differ. Greater exposed area could also affect evaporation. Use identical trays with equal water amounts and matched timing, varying only the intended exposure. The present evidence describes a difference without isolating its cause.
Problem 2
Answer and explanation
The observation is that the rock contains shells of marine organisms and is now at high altitude. The inference is that the rock formed on a sea floor and was later uplifted. The first is what anyone can verify directly; the second is a conclusion drawn from it using what we know about where such shells form.
