What colors make black ink?
- NGSS Physical Science DCI PS1
- Pre and post-laboratory assessments
- Links to real world concepts
- Estimated class/lab time required: 45 minutes over 1 day
In this lab activity, students will master the techniques of paper chromatography. Using paper chromatography, students will separate the inks of several water soluble pens, calculate the relative rate of flow for each color dye on the chromatogram, and identify a type of pen based upon the quantitative measurements obtained. This activity allows students to explore NGSS Physical Science Disciplinary Core Idea PS1 (Matter and its Interactions).
This kit has been aligned with all published National Standards. Pre- and Post-laboratory assessments and vocabulary words all target specific Science and Engineering Practices and common core standards. The teacher guide also contains specific “Did You Know” concepts that link the real world with the scientific standards explored. A student copymaster is also included.
: Lab materials include Chromatography vials with caps, Chromatography paper strips, 4 different pens with water soluable ink, Rulers, Microfuge tubes, and Pipets. Materials not included are Distilled water; 100 mL, Scissors, Pencils, Notebook paper, and Plain white paper.
