Students assess and experiment with the role of plant pigments in photosynthesis. They relate the basic principles of photosynthesis utilizing paper chromatography to evaluate a hypothesis regarding plant pigments as well as the role of...

Young scholars experiment with Thin Layer Chromatography to separate pigments found in flower petals.

Young scholars identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Students synthesize Indole-3-Acetic acid from 3-indolylacetonitrile. In this biochemistry lesson, students determine the effect of different concentrations of IAA on lima beans. They explain how hormones help in plant development.

Students conduct an experiment to observe photolysis in the lab. In this chemistry lesson, students explain the mechanism behind photolysis. They test the impact of a non-toxic marker to plant metabolism.

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.

Learners examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...

Students work as scientists to simulate testing on soil, plants, and water for foreign chemicals through this series of experiments.

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...

Learners 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 assess...

Students examine diversity on the planet and the differences within a species.  For this investigative lesson students complete a lab that allows students to better understand the relatedness between plants. 

In this biodiversity learning exercise, students determine the relationship and complete the evolutionary tree for the plants listed. Students review genetic code and DNA sequencing. This learning exercise has 1 graphic organizer, 8...

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.

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...

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...

For 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...

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.

This is a site that offers answers to some often hard to answer questions such as why do leaves change colors. Provides an easy to understand answer to the question along with a section that students can read on their own, a puzzle,...
