Use the blurting method for Science revision: retrieve from memory, brain-dump the topic, check gaps, repair weak links, test transfer and return after a delay.

PSLE Science Reality Lab Vol No.585 | Spectral Resolution = 10 nm — Can the Satellite See Ground Details 10 nm Apart?

—

by

Learn why spectral resolution describes wavelength detail, not ground detail, and how to separate spectral, spatial, temporal and radiometric resolution.

PSLE Science Reality Lab Vol No.584 | Daily Mean Streamflow = 100 m³/s — Was the River Flowing at 100 m³/s All Day?

—

by

Learn why daily mean streamflow summarizes changing river flow over 24 hours, not a constant all-day value, using PSLE Science evidence reasoning.

PSLE Science Reality Lab Vol No.583 | Storm Tide = 3 m — Did the Storm Surge Alone Raise the Sea by 3 m?

—

by

Learn why storm tide combines astronomical tide and storm surge, and how PSLE Science evidence reasoning prevents coastal water-level claims from being mixed up.
