How do you explain chromatography to a child?
Chromatography is a method using mixed substances that depends on the speed at which they move through special media, or chemical substances. It consists of a stationary phase (a solid) and a mobile phase (a liquid or a gas). The mobile phase flows through the stationary phase.
What is butterfly chromatography?
Chromatography is the process of separating mixtures of different chemicals, so that the individual components can be thoroughly analyzed. Students will create colored butterflies through the process of chromatography, which is the separation of a mixture by passing it in a solution.
What is color chromatography?
Chromatography is one of the simplest techniques for separating the individual components of a mixture. The mixture separates because its components travel across the paper at different rates, based on their attraction to the paper or solubility in the solvent. …
What is the procedure of paper chromatography?
Paper chromatography is a technique in which separation of the components of a mixture is achieved through the action of a single liquid phase in a process similar to adsorption chromatography in columns and in which a sheet of paper of suitable texture and thickness acts as the adsorbent.
What to do with chromatography results for kids?
When they are finished with the science experiment, children can turn their results into chromatography art projects. This post includes variations for kid of all ages! Follow our STEM and STEAM Pinterest board!
What are the basic principles of chromatography?
Understand the basic principles of different kinds of chromatography: paper, thin layer, column, size-exclusion, ion exchange, affinity, and HPLC. Created by Angela Guerrero. This is the currently selected item.
What kind of marker do you use for chromatography?
Be sure to have them try using a black marker as it separates into several colours. Chromatography is the separation of mixtures so this simple experiment is an easy introduction for kids to that concept and also gives further study into colours and shades.
How did kids make chromatography with craft stick?
The kids placed their coffee filter into the jar and rested the craft stick across the top. The tip of the coffee filter was just barely touching the water at the bottom of the jar. Within just a few seconds we watched as the coffee filter absorbed the water and drew it upwards.
