“KHOA HỌC TỰ NHIÊN 9” is a text effect created with FontVibe AI.

A disciplined secondary-school science poster set inside a dark graphite laboratory wall, with a wide central field of matte charcoal paneling. Along the outer margins, arrange faint technical diagrams in thin desaturated cyan and muted amber linework: atom orbit schematics, a prism splitting a narrow beam, molecular bonds, a pendulum trace, a leaf cross-section, and small measurement ticks. Keep every diagram low contrast and partially cropped at the frame edges so the center remains clear. A narrow band of cool white light falls from high left across the wall, while a warmer tungsten practical glow is visible as a soft pool near the lower right, creating structured depth in the environment only. Place the exact text "KHOA HỌC" on the first line, "TỰ NHIÊN" on the second, and "9" centered beneath with generous vertical separation; use a centered, poster-scale composition occupying the middle two-thirds of the frame. Preserve crisp empty space immediately surrounding each line. At the base, a black lab bench silhouette holds out-of-focus glass flasks, a small globe, and a metal microscope, all kept below the text area. Fine airborne chalk dust catches the side light without crossing the lettering. Clean editorial print composition, sharp focus at the text plane, restrained cyan-charcoal-amber palette.
