Scientist Analyzing Chemical Sample in Lab - Illustration #3056013 (License: Personal Use)

The black-and-white line drawing shows a bespectacled scientist holding a test tube, brow furrowed, with a large question mark hovering above his head. On the lab bench sit a round-bottom flask connected to a condenser, a beaker with liquid, and a mortar beneath the table-suggesting organic synthesis or analytical work. The illustration conveys curiosity, experimentation, and the iterative nature of scientific discovery.

Used in educational websites, science blogs, or chemistry curriculum pages to visually represent hypothesis formation, lab troubleshooting, or introductory scientific method concepts; targets students, teachers, and curious learners.
