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. 

Learners examine the role of minerals in industries. They use minerals that are found in the grocery store to complete flame tests. They complete an experiment using fireworks.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Students write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

Students engage in a lesson about the scientific concept of matter. They use essential questions in order to guide the research process. Students engage in several class inquiries that are hands on in order to investigate the properties...

In this chemistry worksheet, students use the clues at the bottom of the sheet to complete the crossword puzzle on metals. There are 21 clues to solve on the sheet.

For this catalysts worksheet, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

In this science worksheet, students take a close look at the composition of air while focusing on the content of oxygen. They use clay to model the amounts.

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

Students identify the various components of air as they demonstrate that air is present in the environment.

Learners calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Students explore protein purification by separating a positively charged molecule, lysozyme, from a negatively charged molecule, albumin, at neutral pH using ion exchange chromatography.

Assess your knowledge of mixtures and compounds and your ability to identify real-world examples with this interactive multiple choice quiz. Immediate feedback is provided.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

Learn about the classification of matter based on whether the chemical composition is pure or a mixture. Understand the definitions of elements, compounds, substances, and mixtures, and what the differences are between them. Five types...

In this instructional activity the students will learn how to classify the materials as mixtures, elements and compounds and identify the properties of each group. Also the concept of separation of mixtures will be introduced to the...

This hands-on activity will help the students have a better understanding of different types of materials as pure substances and mixtures and distinguishes the homogeneous and heterogeneous mixtures by discussing some material they use...

Given descriptions, scenarios, or illustrations of properties, students will distinguish between pure substances and mixtures.

As a chemist, you will learn to deal with complex mixtures of many compounds. In this interactive activity, you will learn the basis of separations using acid-base extraction. In the virtual lab you will simulate an actual experiment and...

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...

Defines matter, substances, and mixtures and gives examples.

Provides definitions and characteristics of elements, compounds, and mixtures, and gives an animated image of each.

[Free Registration/Login may be required to access all resource tools.] Students will use the physical and chemical properties of matter to categorize the various forms of matter.

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.
