This collection has 22 free science coloring pages in two clearly different halves: ten cartoon lab scenes with a child or scientist in them, and twelve equipment pages — atoms, DNA helices, molecule chains, flasks, microscopes — drawn on their own with no characters. Every page is black and white on US Letter, downloads as a free PDF, and needs no signup.
That split is what makes the set usable past primary school. The cartoon scenes are for young children who want a story: a bubbling flask, wild hair, a dog in a lab coat. The equipment pages have no cartoon in them at all, which is why they hold up as a middle-school handout — a double helix beside a benzene ring is a diagram a student can label as well as color.
What’s in this collection
Ten cartoon lab scenes and twelve equipment and symbol pages — 22 in total, in the grid below. Each has its own Download PDF and Print button, so you can take one page instead of the whole set.
Cartoon lab scenes
Ten pages put someone in the picture: a girl in goggles mixing at a bench, a boy watching a flask erupt, a scientist with hair standing on end, two children working side by side, a teddy bear reading with test tubes around it, a dog being examined by a man with a stethoscope, a child floating among planets. Thick outlines and busy backgrounds — these are the pages for ages 4 to 8.
Atoms, DNA and molecules
Six pages are built from the icons of chemistry and biology: an atom with its electron orbits, a double helix, ball-and-stick molecule chains, a benzene ring. They are drawn clean and large, with each sphere and bond its own enclosed area, which makes them the best pages here for practising two or three colors in a repeating scheme.
Lab equipment pages
Six more pages show the apparatus with nothing else on the sheet: a rack of test tubes, a conical flask half full, a distillation set-up on a stand, a microscope beside a cell, a magnet with a light bulb, a radiation symbol under a magnifying glass. Empty white space around each object, so a child can add their own background — or a teacher can leave room for labels.
How to print these
Every page is US Letter (8.5 × 11 in), pure black and white, with the drawing inside the printable margin. Plain copy paper is fine; choose “Fit to page” if your printer asks. The equipment pages have wide empty areas, so they take a marker without bleeding — useful if you plan to write labels on them.
FAQ
Are any of these suitable for middle school?
Twelve of them. The atom, DNA, molecule and lab-equipment pages carry no cartoon element, so they work as a labelling or revision sheet as well as a coloring page.
Which pages suit a kindergartener?
The ten cartoon lab scenes. Thick outlines, large characters, and something happening in every one of them.
Do the pages have any text or labels on them?
No — the sheets are drawings only. That is deliberate: it leaves room for a student to add the labels themselves.
Do I need a color printer?
No. Every page prints in black and white; the color comes from your pencils or crayons.
For more pages that teach while they color, the solar system coloring pages include a labelled chart of the planets, and the math coloring pages put a problem inside every section of the picture.
