Advanced chemistry scholars read about gas chromatography as a means of separating mixtures into their components. Then they try the technique on fingernail polish remover. Detailed instructions are provided via a lab sheet for your...

Student learn about "chromatography" in a hands-on experiment. Pupils make a chart showing what the colors represent.

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

In this relationships and biodiversity instructional activity, high schoolers investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and...

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...

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.

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.
