Science (STEM / STEAM) for Kids: Chromatography Butterfly Craft- Explore chromatography with coffee filters and turn your results into colorful butterflies! Perfect for spring or a color unit. ~ Buggy and Buddy
A fun chromatography lab with filter paper as the solid phase and isopropyl alcohol/water as the mobile phase. We tested 2 brands of water-soluble markers and 2 brands of permanent markers. The students got an appreciation that "green" isn't just "green".
