Documenting material experiments for GCSE

A trial only works if one thing changes at a time
AO2 rewards genuine experimentation, and a genuine experiment changes ONE variable and holds the rest constant. Testing three different papers with three different media at once produces results nobody can read — was the outcome about the paper or the media? A useful trial answers one question at a time.
A worked trial: which paper holds a wash
Three identical washes, same brush, same amount of water, same pigment, painted onto three different papers side by side. CARTRIDGE: buckles, the wash pools unevenly. WATERCOLOUR PAPER: stays flat, the wash dries even. TRACING PAPER: barely absorbs, pigment sits on the surface and can be wiped off. One variable — the paper — with everything else held constant, so the difference in result can only be about the paper.
A grid beats a scatter of separate tests
Laying trials out in a grid, side by side on one page, lets a marker compare them directly — and lets the maker compare them directly too, which is the actual point. Scattered tests across different pages, done days apart with slightly different conditions each time, are far harder to draw a real conclusion from, even when each individual test was done carefully. The grid format is what turns several trials into one readable comparison.
A rejected material is still evidence
A material trial that produces a poor result has not failed the assessment — leaving it out of the sketchbook would be the failure. "Tested tissue paper collage over acrylic: the tissue disintegrated once the acrylic was wet, unusable here" is a genuine finding, and the annotation explaining what happened and why is worth marks the blank space where it should have been is not.
Turning a result into the next decision
A trial is only useful once its outcome changes what happens next. "Watercolour paper held the wash best, so the final piece uses watercolour paper" closes the loop between testing and deciding. A page of trials with no stated conclusion, and a final piece that does not obviously follow from any of them, wastes the work the trials represent.
What a strong experiment page contains
One stated question. Several results laid out so they can be compared directly. A sentence naming what changed between them. And a decision about what happens next, tied explicitly back to the results. Missing any one of these turns a genuine experiment into what merely LOOKS like one.
