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

Explains what chromatography is and how its principles are applied when separating mixtures.

An excellent discussion of color mixtures, and how they can be separated by paper chromatography.

To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use...

Many substances are actually mixtures of different things. For example, milk, which looks like it is one substance, is actually a mixture of many different solids and liquids. Chromatography is a technique that is used to separate...

Explains the distinction between the two main types of chromatography - analytical and preparative - and describes eleven chromatography techniques.

Follow these illustrated, step-by-step instructions to use chromatography as a tool in identifying a mystery candy.

Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different...

This project will teach you the basics of analytical chemistry, which is a must for students who want to go into chemistry or materials science. The molecules in objects we see all around us are constantly attracting each other....

In this experiment, you learn about chromatography when you separate the dyes in candies like M & M's and Skittles to see how many dyes are in each color.

Students will practice the technique of chromatography by separating a mixture of FD&C dyes. Questions related to the experiment along with the answers are available for use by the teacher.

For this chromatography experiment, students will investigate pigments used to create a black, water soluble marker. An extension can be done using primary and secondary colored water soluble markers as well as spinach leaves.

In this experiment, students will explore the properties of color using chromatography then observe and compare color patterns to differentiate compositions of various colors.

Find out why leaves change color in the fall, and learn how to do paper chromatography to separate the pigments found in a leaf. [4:24]

The following simulation explores the process of of chromatography and equilibrium.

An lab experiment where students see how molecules move by doing paper chromatography. Site includes student handout and teacher presentation.

This page uses diagrams and charts along with written text to explain gas chromatography.

Young scholars investigate who stole the class pet by testing the chromatograph of different markers as a way to find the evidence that points to the perpetrator.

One of the characteristics that makes M&Ms so popular is dye that colors the hard shell, and of course the chocolate. But, many are unaware of what dyes are used to make those colors. This day long lab uses paper chromatography to...

Explains what chromatography is, some of its applications, and how it works.

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Students will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and solvents....

Using simple household items like M&Ms and coffee filters, you can demonstrate paper chromatography. This simple lab will show you the dyes that make up the different color coatings on M&Ms.

This comprehensive interactive tutorial continues to explore the forensic science field. Learn how organic materials of evidence are analyzed and what the various types of chromatography are, especially why they are so important to this...

In this biotechnology science fair project, determine the relative size of green fluorescent protein, using size-exclusion chromatography. The Science Buddies project ideas are set up consistently beginning with an abstract, objective,...
