Pupils use thin layer chromatography, TLC, to separate various pigments found in plants.

Fifth graders perform experiments with color mixing and color changing. They observe the differences between physical and chemical changes and record their observations in journals.

Students isolate and identify a dye, which represents a synthetic pesticide, from plants.

Students are introduced to working with molecular data. The first activity does both simulated and original data are used to compare amino acid, protein or DNA differences to construct phylogenetic trees or cladograms. These activities...

High schoolers examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and...

Are all reds the same? Find out in this science fair project. Investigate if the pigments in one type of red flower are different from those in another type of red flower. Flowers contain an assortment of amazing chemicals that produce...

In this hands-on, inquiry based lesson students will see the role of pigments in the in the process of photosynthesis. Students will use the process of chromatography to separate plant pigments. Students will then see the function of...

Everyone loves the beautiful colors of fall, but where they come from and how they change color is a mystery. In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography.

Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plant pigments. Pigments are what make the world around us so colorful. How do chemists turn those natural plant...

A step-by-step procedure with pictures for the process of chromatography. Chromatography allows students to see the pigments or coloring of the tissues of plants.
