Students identify chromatography as method of separating the components of a liquid. Students discover that dyes are composed of more than one component in achieving a particular color in these lessons on paper chromatography.

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

Learners identify DNA in a crime scenario. In this DNA lesson, students perform paper chromatography and compare it against the pens of various suspects.

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

Students explain the process of TLC. They identify at least three components of ink. They analyze data and make conclusions based on laboratory observations.

Students explore the process of photosynthesis by identifying chloroplasts and chlorophyll pigments. In a demonstration, they observe a demonstration connecting pigments with sunlight conversion into energy. Using paper chromatography,...

Third graders use logic and knowledge of mathematics facts to solve problems. They see that pigments can be broken down into separate colors. Pupils recognize the capacity of water to move upward and measure the height water travels up...

The intent of this series of activities is to introduce high schoolers to the field of chemical instrumentaiton. They perform a few basic chemistry lab techniques: pH titration, paper, gas, and liquid chromatography, ultraviolet and...

Fifth graders study the scientific method and understand how to apply it.  In this "thinking like a scientist" lesson students complete several activities.

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 test fluids for amino acids, glucose and salicyclic acid. In this chemistry indicators lesson plan, students use chromatography paper, Benedicts solution and iron chloride to test solutions for amino acids, glucose, and...

Young scholars identify the different components of a given sample using chromatography. In this chemistry lesson, students compare paper and column chromatography. They collect data and construct data tables.

Young scholars discover the roles of pigments present in leaves. They extract and isolate pigments present in autumn leaves using a thin layer chromatography. Very nice activity and lab!

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. 

Students discuss DNA Fingerprinting and gel electrophoresis before participating in a crime solving activity. Students simulate their DNA using adding tape and complete the steps necessary to do a gel electrophoresis. They discuss the...

Students identify several properties of water as a universal substance, describe the composition of several complex color mixtures and separate the components of dye using chromatographic technique.

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 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...

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...

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

In this lesson plan, students will make a chromatogram of different types of ink. Paper chromatography will be used to detect the different dyes used in the ink. This lesson plan can be used for both Physical Science and Chemistry classes.
