Today in Science we are learning about Chromatography.
Whats is Chromatography? Chromato means Colour and Graphy means writing or science.
Whats are pigments? The pigment is a substance that gives colour to things. They are used to give colour to all sorts of things like felts, paints, plastic, food, fabric, even animals and plants.
Aim-To separates the different pigments from ink using the chromatography
hypothesis- I think that the pen line will go up and take out the pigments, the colours we might see are orange blue and black. (depended on the pen
1- Draw a line across the filter paper in pencil, 5cm from the bottom.
2- Draw a coloured dot in the centre of the line.
3- Measure out 10mL of water and place it in the test tube.
4- Place the filter paper in the test tube and fold it over the side. MAKE SURE THE PENCIL LINE/ DOT IS NOT IN THE WATER.
5- Wait for 5 minutes and observe the results
EQUIPMENT- Felt tip pen, filter paper strips, test tube, measuring cylinder, pencil.
