Science among its neighbours
Chemistry has flasks and formulas, Physics has forces and circuits, Biology has cells and organs. Science is the general shelf for the process of finding out: experiments, lab sheets, the hands-on part of a school subject.
The experiment scene
Clean outlines and pale fills, no text, so it fits a worksheet header, a science-fair poster or a slide on lab safety without clashing with the page.
The pulley worksheet
A real printed handout with a problem, materials list, numbered steps and two apparatus drawings. Useful as a sample of how a lab report is laid out, or as a background prop in a teaching blog.
