Core Skills Analysis
Science
- Understanding the physical process of chromatography and how solvents can separate mixtures based on different pigment solubility.
- Gaining hands-on experience with experimental setup: using filter paper as a medium and water as the solvent to observe ink separation.
- Observing color properties and how complex colors like those in felt tip pens consist of multiple pigments.
- Developing skills in making observations, predicting outcomes, and drawing conclusions based on visual results of the experiment.
Art
- Exploring the hidden colors within standard felt tip pens by separating pigments, linking scientific and artistic perspectives.
- Using color and design principles to create patterns that can change dynamically when exposed to water.
- Enhancing fine motor skills and precision with drawing lines on filter paper as part of the experiment.
- Stimulating creativity through observing surprising color combinations and effects during the chromatography process.
Tips
Tips: To deepen Ted's understanding and make the chromatography activity more engaging, encourage him to experiment with different types of pens or markers (such as water-based, permanent, or gel pens) to compare how pigments separate differently. Try using various solvents like alcohol or vinegar to observe changes in pigment separation beyond water. Integrate cross-disciplinary learning by combining science with art—Ted could design colorful patterns on filter paper before performing chromatography to see how art transforms under the scientific process. Another idea is to challenge Ted to hypothesize what colors might emerge from mixed or blended ink lines and record his predictions and observations. Lastly, discussing the real-life applications of chromatography, such as forensic science or environmental testing, can help Ted connect classroom learning to everyday life.
