Test Tube Science Lab Coloring Page

This coloring page shows a science lab workbench with a tall test tube full of layers from a color-separating experiment. A dropper adds more liquid, and simple flasks, beakers, and measuring tools sit nearby. Perfect for kids who love science.

Fun facts

Test tubes are made of glass or plastic to hold small amounts of liquids for experiments.
Scientists use droppers to add exact drops of liquids without spilling.
Color separation happens in real life when different colors in ink spread out in water.

Coloring tips

Use different bright colors for each layer in the test tube to show the separated liquids.
Color the dropper tip blue or red to match the drop falling into the tube.
Add fun lab colors to the flasks and beakers next to the workbench.
