Students extract DNA from animal liver cells. They separate, collect and describe the appearance from the extracted DNA while role playing as an intern in a city's forensics.

Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.

Students discover the many uses of minerals in industry. They use minerals to conduct flame tests and to demostrate color. They practice safety tips in the lab.

In this fermentation learning exercise, learners conduct an experiment to illustrate how the yeast fermentation process is used to produce carbonation. This learning exercise has 5 short answer questions.

Students separate food coloring using liquid chromatography. In this chemistry lesson, students explain the effects of different solvents on the rate of separation.

Middle schoolers use TLC separations to identify various substances.  In this chlorophyll lesson students separate pigments found in different plants.

Learners use thin layer chromatography, TLC, to separate various pigments found in plants.

Students identify the composition of different pennies. In this chemistry lesson, students use a post 1982 penny to observe chemical change. They explain how to turn a penny from copper to gold.

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...

In this lab, students will demonstrate observation skills as they design an experiment to separate colors of various water-based pens in order to learn about mixtures and solutions. Students will determine a variable to test and complete...

In this chemistry lab, students investigate whether water molecules have any space between them by filling a glass with water, and adding salt without the water overflowing. They will also experiment with the temperature of the water.

During this lab students will experiment to see whether a salt and vinegar solution can clean a tarnished penny. Included on site is lesson plan and student worksheet.

A laboratory experiment where students classify matter into a homogenous mixture, heterogeneous mixture, solution, or pure substance. Also students will test for physical and chemical changes.

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....
