Science Color By Number Worksheets (9 Free Coloring Pages)
Science color by number worksheets became one of my favorite low-prep ways to sneak in science when my son just wanted to color.
Instead of a full lesson, we’d sit down with crayons and talk about planets, magnets, or microscopes, just enough to get him curious.
These worked especially well during quiet time or transitions between subjects.
If you’re looking for something fun that still builds early STEM skills like number recognition and observation, these free color by number printables do a great job of making science feel accessible and creative.

How to Use These Worksheets to Build STEM Skills
We mostly used these during quiet time or as a way to ease into new science topics. But I quickly realized they were doing more than just keeping my son busy.
- Matching numbers helped reinforce early math without him noticing.
- Coloring things like flasks and magnets gave us an easy way to talk about new vocabulary.
- It also gave him confidence, he felt like he understood science just by recognizing the tools and ideas.
You can also add these to a science journal, pair them with hands-on experiments, or just use them as a creative transition between lessons.
