Leaf Chromatography

Students use chromatography to separate plant pigments collected from a fictitious crime scene and suspects. They compare the Rf values of the plant pigments to determine whether the plant pigments found on any of the suspects match the...

Students participate in a three-part lab in which they investigate plant pigments. Part I is designed to teach basic laboratory techniques of column chromatography, in Part II students design an experiment to separate the components of a...

Take a good look at tree leaves and notice the adaptations for collecting solar energy. Pupils trace the margins of five different leaves onto graph paper and count the number of squares covered. They then relate this infomation to the...

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion...

Learn about dichotomous keys, plant identification, and how to care for the planet with a lesson that includes several hands-on and innovative activities. Kids go on a plant scavenger hunt and classify the plants that they find...

Here's an activity that will change how one sees color. Pupils try out an experiment on chromatography where they place a drop of food coloring on a coffee filter, add several drops of water, and watch the colors spread and separate....

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

Why can't plants escape prison? Because their cells were surrounded by walls. Introduce viewers to the evolution of plants with a video that discusses the differences between prokaryotic and eukaryotic cells, plant cells' organelles, and...

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.

For this hands-on, inquiry based lesson young scholars will see the role of pigments in the in the process of photosynthesis. Students will use the process of chromatography to separate plant pigments. Young scholars will then see the...
