Explicit physics instruction
Different materials reflect, absorb, and emit different fractions across wavelength bands, creating spectral signatures.
Inference requires calibration and comparison with references; one color or band rarely identifies a target uniquely.
Spatial, spectral, and temporal resolution tradeoffs influence what questions a remote-sensing system can answer.
Vocabulary: spectral signature; calibration; band; spatial resolution; inference.
Worked example
A surface that strongly reflects near-infrared but absorbs red light can be distinguished from another surface using a ratio or multi-band pattern.
Guided question
Why is a multi-band pattern stronger evidence than one brightness value?
Independent work
- Compare three synthetic spectral signatures.
- Identify one likely match to a reference.
- State one ambiguity or confounder.
Misconception check
A bright pixel is not automatically one material; brightness depends on illumination, geometry, sensor response, and wavelength.
Formative check
What makes a remote-sensing inference traceable?
Reveal response
Calibrated measurements, stated bands, reference comparisons, and uncertainty.
Mentor evidence conference
Ask Archaemenes to separate direct measurement from inference and audit model assumptions.
