Naming Atoms—Elements, Ions and
Isotopes—Super Value Laboratory Kit
By: The Flinn Staff
In order for students to understand the fundamentals of chemistry, they must start small. What makes up an atom? Why is each element unique? What constitutes an isotope? How are ions formed? In this activity, 18 workstations are created, each containing various numbers of blue marbles (neutrons), black marbles (protons) and a number of electrons. At each station, students use their knowledge of the nucleus, along with the periodic table, to determine if the bag of marbles represents an element or ion. This simple and straightforward activity helps students understand the basics of a fundamental atomic concept, the nucleus and the particles that compose it. Includes student handouts, Instructor’s Notes and all necessary supplies.
Super Value Kit is complete for 15 student groups. All materials are reusable.
Quantum Leap—Student Laboratory Kit
By: Eve Krupka
Mount St. Mary Academy, Watchung, NJ
Take a “quantum leap” to see if you can determine the precise location of an electron around the nucleus of an atom! This engaging lab helps students visualize the shapes and relative positions of the 1s and 2s orbitals in a hydrogen atom. It also brings quantum mechanics to a more understandable level—illustrating the concepts of probability, electron density and Heisenberg’s uncertainty principle. In this activity, students drop marbles onto specialized carbonless bull’s-eye target sheets from various heights, examine the patterns formed and relate the results to the maximum spot density of the s orbital. Includes 30 printed carbon- less target sheets, marbles, reproducible student instructions with data/ graphing sheets, analysis questions, Instructor’s Notes, sample data and graphs. Also included is an optional performance assessment. Target Sheet Refill Pack includes 30 replacement printed carbonless target sheets—15 for waist-level and 15 for eye-level targeting.
Complete for 30 students working in pairs.

Atomic Structure—Demonstration Kits
Molecular Motion Demonstrator—
Demonstration Kit
By: The Flinn Staff
Help your students visualize molecular motion concepts with this dramatic demonstration device. Just pour the simulated molecules (BBs) into the clear acrylic chamber and focus it on your overhead projector. By varying the number of molecules and movement of the apparatus, you can illustrate the structure of substances in various states, such as solid, liquid and gas. Random molecular motion, molecular distances, kinetic theory and molecular structure of specific substances can all be illustrated with the same device. The kit includes the reaction chamber, the BBs and instructor notes.
Concepts: Molecular motion, kinetic molecular theory.
Time Required: 15 minutes
Materials Provided: Molecular Motion Demonstrator, copper shot.
