Explain a measurement so that a comparison is fair
Einen Versuch nachvollziehbar erklären
Describe a procedure with clear agents and conditions, and compare absolute and relative measurements without inventing a universal ranking.
Scientific explanation needs more than a result. State what was measured, how and under which conditions. Two fictional samples are weighed dry and after ten minutes in water: A changes from 40 g to 48 g, B from 50 g to 60 g. The absolute increases are 8 g and 10 g; relative to dry mass, both are 20 percent. Thus B takes up more grams in this measurement, but neither has a higher relative increase. Mit derselben Waage and nach derselben Zeit describe comparable conditions; they do not make two differently sized samples identical. Only one measurement per sample is supplied, so repeatability and general material performance remain untested. Passive sentences foreground the procedure: Die Proben wurden gewogen. An active version can name a known agent: Das Team wog die Proben. Do not invent an agent where none is reported.
Das Team wog beide Proben vor und nach dem Versuch.
The team weighed both samples before and after the experiment.
Die Proben wurden jeweils zehn Minuten ins Wasser gelegt.
The samples were each placed in water for ten minutes.
Anschließend wurden sie mit derselben Waage erneut gewogen.
They were then weighed again using the same balance.
Probe A nahm acht Gramm, Probe B zehn Gramm zu.
Sample A increased by eight grams and sample B by ten grams.
Bezogen auf die Ausgangsmasse beträgt die Zunahme bei beiden zwanzig Prozent.
Relative to initial mass, the increase is twenty percent for both.
Eine einzelne Messung erlaubt noch keine Aussage über die Wiederholbarkeit.
A single measurement does not yet establish repeatability.

Describe a procedure with clear agents and conditions, and compare absolute and relative measurements without inventing a universal ranking.
Do not declare B universally more absorbent solely because it gained more grams, or claim repeated confirmation from a single measurement.
Define measured quantity and procedure; retain starting mass, time and instrument; distinguish absolute from relative change and a single observation from a general conclusion.
Write a 180–220-word German explanation for classmates: sample A dry 40 g, wet 48 g; B dry 50 g, wet 60 g; both immersed for ten minutes and weighed on the same balance; one measurement per sample, no further material information. Describe the procedure, compare both absolute and relative changes and propose a repeat measurement. Use one passive and one active sentence with the team as agent.
