Teach Engineering: Mixtures and 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 of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table-one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are discussed.
