A hands-on experiment applies chromatography to separate both the colors and components of grape-flavored Kool-Aid. Performing two separate activities, learners first use chromatography to divide the colors. The second activity results...

Here is a different approach to solutions: a instructional activity that has chemistry learners use words to describe them! This is an outstanding exercise that will stretch learners to show what they know. They answer questions...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Fifth graders design an experiment in which they separate mixtures. For this mixtures lesson, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate...

In this soap worksheet, students produce soap in the laboratory and test their product by washing away engine oil with their soap. Students answer four questions about tests they perform on their soap.

Students develop simple observations. They observe bleeding of colored inks with water, to understand mixtures, and to make generalized inferences from their observations.

Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

In this compounds worksheet, students compare the differences between compounds and mixtures. This worksheet has 3 short answer questions.

In this classification of changes worksheet, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...

In this 9th grade science review worksheet, students complete 63 true or false questions on topics such as atomic notation, isotopes, covalent bonds, Ohm's law, and electric circuits.

In this matter worksheet, students complete a table in which they compare elements, compounds, and mixtures. Once table is finished, they answer 6 fill in the blank questions.

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.

Learners examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Students listen to the book, "Oobleck," by Dr. Suess before experimenting with mystery powders. They determine the proper ratio of powder to liquid to make the Oobleck.

In this solutions worksheet, students will write down two properties that solutions have and then will come up with a conclusion about solutions based on their facts.

In this matter worksheet, students will brainstorm two examples of a pure substance and two examples of a mixture and write these into a graphic organizer.

Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.

Students explore conductivity and productivity in aquatic systems.

[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...

[Free Registration/Login may be required to access all resource tools.] Solve problems that deal with a mixture of two things using the substitution method.

A ten-question quiz on the chemical properties of mixtures.

[Free Registration/Login may be required to access all resource tools.] Discusses elements, atoms, compounds, molecules, and crystals. Looks at mixture and different types of them.
