Ten experiments in which students differentiate between physical and chemical properties and explore the characteristics of matter; color, odor, solubility, shape, size, texture, density, alkalinity, acidity, states of matter, boiling point, and melting point. Includes graphing of melting and boiling points. Students observe chemical properties of five solutions by observing their reactions with other solutions. From these reactions, students then determine the identity of two unknown solutions. Includes reproducible students data sheets, assessment questions, and answer keys. Required, but not included: balance, ice, glassware. Meets national standards for grades 6-9.
