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...

Choosing two different powders, students will evaluate the properties of the materials and if the materials, when mixed with 50 ml of water, make a mixture or solution. They will examine the difference between a mixture and a solution...

With an overview of seven topics related to solutions, this .pdf file provides information on everything from osmosis and osmotic pressure to ions in aqueous solution. Other topics include solutions of volatile substances, methods of...

In this module, students study solutions; how they are formed, how to calculate concentration of solutions, and what the colligative properties of solutions are.

This Chem4kids tutorial teaches the basic properties of solutions.

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...

What's in macaroni salad? Break down the pasta, mayonnaise, vinegar, mustard, vegetables, etc., and you're left with a bunch of molecules. Josh Kurz uses a delicious recipe to exemplify three types of mixtures (solution, colloid and...

In this lesson 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 students. Since...

Learn the definitions of a solution, solute, and solvent. Understand how molarity is used to quantify the concentration of solute, and comcalculations related to molarity.

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...

Listen and learn about Arrhenius acid-base reactions while exploring mixtures, solutions, and their reactions. Examine the photos of the examples discussed in this website and discover how arrhenius acid-base reactions occur.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students expand their study of mixtures to show that solids and gases can also act as solvents. Additionally, they take a look at situations in which...

Students investigate the property dependence between concentrations and boiling point. First, they investigate the boiling point of various liquid solutions. Then they analyze data collected from the entire class to generate two boiling...

Students investigate the property dependence between concentrations and boiling point. In Section 1, students first investigate the boiling point of various liquid solutions. In Section 2 they analyze data collected from the entire class...

A discussion of the "other" mixtures, colloids and suspensions. A good overview of these types of mixtures. It also provides a table of the properties of colloids.

In this activity, students investigate the properties of a heterogeneous mixture, trail mix, as if it were a contaminated soil sample near a construction site. This activity shows students that heterogeneous mixtures can be separated by...

[Free Registration/Login may be required to access all resource tools.] Discusses how mixtures of solids can be separated based on observable properties of their parts such as particle size, shape, color, and magnetic attraction.

[Free Registration/Login Required] This flipchart introduces fifth graders to mixtures, solutions, and suspensions. Opportunities for student participation and an assessment are included.

Demonstrates, step-by-step and with examples, how to set up and solve 'mixture' word problems.

Do you know the difference between a mixture and a solution? Test your knowledge in the junkyard as you try to dissolve various objects in water. Requires Shockwave.

Explore all about chemical mixtures on this site including solutions, alloys, suspensions, colloids, dissolving, examples, and facts.

Resource contains and example problem and solution of how to compute percent compound within a mixture when given the mixture's mass and element percents.

Explains what the Tyndall Effect is and uses a diagram to model its impact on two different mixtures. Includes causes, examples, a look at suspensions and solutions, and an experiment to try.

[Free Registration/Login Required] Physical and chemical changes are defined and examples are given of each. Practice with determining the difference between mixtures and solutions are also given. Links to external sites for practice...
