In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.
A development of the atomic molecular theory from the law of multiple proportions and law of definite proportions.

Students are introduced to the concept of different kinds of matter. Students create models of different substances to learn to identify the differences between elements, compounds, and mixtures. This lesson is developed so that teachers can use it with English as a Second Language students.
Learners respond confidently to their desire to learn about natural phenomena; they investigate relationships and solve problems within the context of science, technology and the environment. In this activity, learners will show an understanding of the interrelationships between science and technology, society and the environment.
This lesson plan introduces the properties of mixtures and solutions. A class demonstration gives the students the opportunity to compare and contrast the physical characteristics of a few simple mixtures and solutions. Students discuss the separation of mixtures and solutions back into their original components as well as different engineering applications of 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.
This is a lab activity where students will investigate solubility or miscibility of eight substances with water.
