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...

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 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.

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...

Avogadro's law is stated in equation form. The lesson does not include much discussion, but it does relate the partial pressure and the total pressure of a gas sample to the mole fraction of its components.
