Learners learn the importance of caring for eggs as they hatch chickens. In this egg hatching lesson, students observe what happens when eggs are hatched into chickens by completing a e-worksheet and watching a web based movie.

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. 

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...

Young scholars gain experience in asking questions and conducting inquiry by exploring the separation of colors in water and other solvents; to communicate and share findings of student investigations.

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...

Students discuss the murders of Native Americans in Indiana. In groups, they research and make drawings of the scene as if they were part of a CSI team. They complete any needed experiments to help them solve the crime and create a...

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

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

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...

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

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....

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

Explains what paper chromatography is, how it is done, and how the Rf or Retention Factor is calculated.

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]

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.

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...

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...

This lesson focuses on analyzing and identifying substances. Substances can be analyzed using a variety of methods including paper chromatography, gas chromatography and mass spectrometry. After reading about the different techniques,...

This lesson plan can be used to illustrate the principle of electrophoresis without the equipment. Paper chromatography can be used to separate dye just like electrophoresis will separate DNA. The lab also covers DNA analysis for an...

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...

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....

In this lesson students use simple paper chromatography to investigate a mystery liquid. Student sheets are provided in English and in Spanish.
