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.

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...

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

[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...

For 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.

This is a complete course in chemical stoichiometry, set in a scenario that shows how stoichiometry calculations are used in real-world situations. This course has been designed to not only help you strengthen your skills with...

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.

Students conduct an experiment to determine how varying the composition of a construction material affects its strength. They make several adobe bricks with differing percentages of sand, soil, fibrous material and water. They test the...

[Free Registration/Login Required] This flipchart provides a multitude of hands-on activities for identifying, arranging and creating sentence maps for various water and aqueous systems.

[Free Registration/Login Required] This flipchart is a guided activity to help students compare different types of matter: atoms and molecules, elements and compounds, mixtures and solutions. It corresponds to Virginia science SOL 5.4.

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...

This lesson will explain the properties of a suspension, and describe why it is unique from other mixtures. It is 2 of 2 in the series titled "Suspensions."

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....
