Periodic Table and Trends—Laboratory Kits
Chlorides, Bromides and Iodides—
Student Laboratory Kit
By: Brother Carmen Ciardullo, Retired
St. Joseph’s Prep Seminary, Princeton, NJ
Through microscale qualitative tests, students will learn the properties, ways to identify and test for three types of halides: chlorides, bromides and iodides. Qualitative analysis will give students the knowledge necessary to identify chemical reactions as well as substances. The students’ final quest will be to identify an unknown. The unknown will be a halide salt or a mixture of halide salts. All chemicals and special- ized equipment are provided. Marking pens and test tube racks are required but not provided.
Complete for 30 students working in pairs.

Density Is a Periodic Property—
Super Value Kit
By: The Flinn Staff
Dmitri Mendeleev was not the first scientist to recognize relationships among the elements and classify them into groups. He was, however, the first to predict the existence and properties of missing elements. Introduce students to the periodic table as they re-create in the lab the excitement that followed the prediction and discovery of missing elements. Students measure mass and volume data for silicon, tin, and lead, calculate their densities, and graph the results to predict the density of germanium, the “undiscovered” element in the Group IVA family of elements. Includes reproducible student handouts, detailed background information, and complete Instructor’s Notes with sample data and answers to questions. All of the element samples can be dried and recycled for repeat use.
Super Value Kit is complete for 5 classes of 30 students working in pairs. All materials are reusable.
Families of Elements—
Alkaline Earth Metals & Halides—
Student Laboratory Kit
By: The Flinn Staff
“Metal reactivity increases as you move from top to bottom in a family of elements!” Will your students remember this statement if you just tell them? With this lab kit, students are actively involved in seeing and making observations about the properties, reactivity and solubility of the alkaline earth metals and the halide salts. Students write chemical equations for the reactions they observe and for the precipitates or gases that form. All chemicals, stirrers, reusable pipets and test tubes are provided in kit. Instructor’s Notes and reproducible student handouts included.
Complete for 30 students working in pairs.
