Atomic Structure—Laboratory Kits
Build a Polarimeter— Student Laboratory Kit By: The Flinn Staff
Students get excited about studying organic compounds when they build their very own polarimeter. A wide range of chemicals are able to interact with and rotate polarized light. A polarimeter enables a chemist to investigate the extent of these interactions. This kit contains enough materials to build eight simple polarimeters, which can then be used to measure the rotation of polarized light by sugar solutions.
Complete for 24 students working in groups of three.
Atomic Coatings—The Size of an Atom— Student Laboratory Kit
By: The Flinn Staff
How can we get students to “see” the extremely small size of an atom? In this experiment, students measure the mass of the zinc coating on a piece of galvanized iron by reacting the metal with hydrochloric acid. Only the zinc, not the underlying iron, reacts with the acid under these conditions. The volume and thickness of the zinc coating are also deter- mined. Given the diameter of a zinc atom, students can then “count” the number of layers of atoms in the invisible coating. Includes reproducible student handouts, detailed background information, Instructor’s Notes with sample data and answers to questions, and all necessary chemicals and supplies.
Complete for 30 students working in pairs.

Atomic Target Practice—Rutherford
Scattering and the Nuclear Atom—
Super Value Guided-Inquiry Kit
By: The Flinn Staff
In this activity, students confront a problem similar to the one Rutherford faced. Students shoot marbles at an unknown, unseen object. By tracing the apparent path a marble takes after striking the unseen target from a variety of angles, students can estimate the general size and shape of the target. Use this creative simulation to engage your students in one of the great discoveries of the atomic age. Includes eight wooden shapes, marbles, and all materials needed to construct eight “black boxes.” Reproducible student handouts, detailed background information, and Instructor’s Notes with sample data and answers to questions complete the kit.
Super Value Kit is complete for eight student groups. All materials are reusable.
