Science: Leaf Study
First graders go on a leaf-hunting expedition around the schoolyard. They determine from which trees they fell using identification cards. Students read several books about leaves and apply their artistic skills by using the collected...
Curated OER
Paper Chromatography
Small groups of students perform paper chromatography to separate food dyes into their component colors. Students perform the experiment and collect, organize, and represent their data to form an explanation of their outcomes. Students...
Curated OER
Chromatography
Learners investigate the separation of mixtures using plant pigments. Using everyday items, they demonstrate the separation of pigments in plants through the process of chromatography.
Curated OER
Colored Dots 1
Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.
Curated OER
Using Chromatography to Identify Unknowns
Students are introduced to the concept of chromatography. They practice using new vocabular and observing experiments. They answer discussion questions to end the lesson.
Curated OER
Chromatography
Students research types of chromatography and complete chromatography experiments.
Curated OER
The Conceptual Theory of Chromatography
Students conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab report on...
Curated OER
Hidden Colors
Students discover presence of different colors hidden in green leaves by performing a chromatography experiment on chopped green leaves.
Curated OER
T-shirt Chromatography
Students explore chromatography, a process used to separate mixtures. They create a colorful T-shirt design.
Curated OER
The Perils of Drinking Water
Young scholars determine the presence of drugs in water. In this chemistry lesson, students experiment on water samples using thin layer and column chromatography. They determine the concentration of drugs present using graphical analysis.
Curated OER
Chromatography
Eighth graders observe a compound and separate it into its component parts. In this chromatography lesson students complete and activity that demonstrates how mixtures can be separated into components.
Curated OER
Thin-layer chromatography
Students produce chromatograms of various vegetable extracts and standards. Using a flat bed scanner, they create a database of the results.
Curated OER
Using Ion Exchange Chromatography to Separate Proteins
Pupils explore protein purification by separating a positively charged molecule, lysozyme, from a negatively charged molecule, albumin, at neutral pH using ion exchange chromatography.
Curated OER
Wolf Pack in a Bottle
Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
Science NetLinks: Color Burst
Students 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.
Curated OER
DNA Fingerprinting
Middle schoolers experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
Curated OER
Separation of Unknowns in a Liquid
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.
Curated OER
Paper Chromatography
Students participate in an experiment determining how to separate a mixture of dyes in water-soluble ink.
Curated OER
Introduction to Gas Chromatography
Students analyze gas chromatograms and suggest various applications for gas chromatography.
