Step-by-Step Procedure

  1. 1

    Gather materials and cut coffee filters into strips.

  2. 2

    Dissolve candies in a small amount of water.

  3. 3

    Use a pencil to draw a line on the coffee filter strip.

  4. 4

    Place a drop of the candy solution on the line.

  5. 5

    Suspend the strip in a glass container with a small amount of water.

  6. 6

    Allow the water to rise up the filter and separate the dyes.

  7. 7

    Record the colors that separate as the water rises.

  8. 8

    Compare results from different candies.

Expected Results

It is expected that the different candies will show unique patterns of dye separation, demonstrating how chromatography works.

Variables

Independent Variable

Type of candy used

Dependent Variable

Number of dye colors separated

Controlled Variables

Amount of water used, Size of filter strip, Time allowed for separation

Safety Notes

Ensure to wash hands after handling candies and avoid consuming them while conducting the experiment.

Presentation Tips

  • Create a colorful display of your results.

  • Use images of the chromatography process.

  • Explain the science behind chromatography simply.
