Scientist coloring pages

Bubbles everywhere! A cheerful scientist with curly hair, big glasses and a beard pours a fizzing liquid from one flask into a large bubbling beaker. He wears a roomy lab coat, and his workbench holds a rack of three test tubes and a round-bottom flask. The bold, thick outlines and large open spaces suit little ones aged 2 to 5 who love pretend experiments. Fill each container with a different bright color, like lime green, purple and orange, so the potions look magical. Prints on A4 or US Letter.

In a sunny lab, a smiling bearded scientist in safety glasses carefully pours liquid from a cone-shaped flask into a round one. Around him you can spot a microscope, a rack of test tubes, a measuring beaker, a thick book, a potted plant on a shelf and a window with puffy clouds. Kids aged 5 to 10 will enjoy the mix of big shapes and small lab gear. Use markers in two contrasting colors for the two liquids, then blend them in the round flask where they meet.

Mid-experiment, a bearded scientist with glasses and a neat lab coat pours a pale liquid into a frothing flask, pens tucked in his pocket. The busy lab around him is packed with detail: an atom poster, a microscope, shelves of bottles and jars, trailing ivy, a mortar and pestle, a petri dish, goggles and a spiral notebook with a pen. Fine lines make it a satisfying page for older kids and adults. Try soft colored pencils in cool teal and aqua for the glassware, leaving small white highlights for shine.

Every corner of this dense lab is filled with pattern. A grinning scientist with glasses and a beard pours a bubbling potion into a flask, surrounded by a globe, a microscope, a coiled glass condenser and bottles decorated with moons, stars and flowers. A barn owl watches from the shelf, a striped cat naps on the bench and a planet chart hangs behind him. Made for experienced adult colorists who enjoy zentangle-style detail. Use fine-tip gel pens in jewel tones for the potion bottles so they glow against muted backgrounds. Prints on A4 or US Letter.
