Separating a Mixture by Filtration—
Laboratory Kit
By: The Flinn Staff
Most of the matter around us consists of mixtures, or physical blends, of many substances. The main characteristic of a mixture is that it has a variable compo- sition—the components of the mixture may be mixed in varying proportions. The substances in a mixture retain their distinctive chemical identities, as well as some of their unique physical properties. How are the properties and composition of a mixture affected by physical and chemical changes? In this experiment, students separate a mixture of charcoal and salicylic acid and determine the percent composition of each component in the mixture.
Complete for 24 students working in pairs.
Periodic Trends and the Properties
of Elements—Laboratory Kit
By: The Flinn Staff
The periodic table is the most recognized symbol of chemistry around the world. It is a valuable tool that allows scientists not only to classify the elements but also to explain and predict their properties. Similarities and differences among the elements give rise to so-called periodic trends, both across rows and within columns of the periodic table. Recognizing periodic trends in the physical and chemical properties of the elements is key to understanding the full value of the periodic table.
In this two-part experiment, students first examine periodic trends in the activity and then the solubility of the alkaline earth metals. The trend in metal activity within a group and across a period is determined by comparing the reactions of metals with water and acids. The solubility of alkaline earth metal salts are studied to identify an unknown alkaline earth metal solution.

Classifying Chemical Reactions—
Laboratory Kit
By: The Flinn Staff
The power of chemical reactions to transform our lives is visible all around us—in our homes, in our cars, even in our bodies. Chemists try to make sense of the great variety of chemical reactions the same way that biologists organize their knowledge of life, by sorting reactions into groups and classifying them. Classifying chemical reactions allows us to predict what chemical reactions will occur when different substances are mixed. Students observe a variety of chemical reactions and identify patterns in the conversion of reactants into products. The properties of the reactions will be analyzed to classify the chemical reactions into different groups.
