Lesson Plan: Let it Glow

In this lesson students will investigate the fluorescence of a variety of everyday items as well as prepared samples under a black light. Students will examine the concepts of absorption and subsequent emission of photons, as well as wavelength, frequency, and energy of electromagnetic radiation. As extension activities, students will learn about phosphorescence and research real-life applications of photoluminescence.
Electricity, Electrostatic Forces, Metallic Bonding, Electrons | High School

Demonstration: Metallic Bonding & Magnetics

In this demonstration students will observe how electrons flow through a metal in an example of metallic bonding. Using tubes made of different metal materials as well as one made of plastic, in combination with a rare earth magnet (neodymium magnet) the teacher will demonstrate how electrons will flow freely through a metal and create a magnetic field.
Model of the Atom, Atomic Mass, Subatomic Particles, Electrons | High School, Middle School

Project: Element Project

In this project, students will become familiar with and have a workable understanding of atomic structure. The students will also create and construct a model of an atom.

Lab: Making the Connection

In this lab, students will learn about closed and open circuits. Students will use holiday lights, a battery, and foil to make a closed circuit.
Periodic Table, Electron Configuration, Valence Electrons, Electrons | High School

Lesson Plan: Electron Configuration and the Periodic Table

In this lesson, students will learn how the periodic table can be used to predict the electron configuration of an atom and, thus, better predict the reactivity of an atom.
Introduction, Elements, History, Periodic Table, Atoms, Valence Electrons, Subatomic Particles, Electrons | Middle School

Project: Elemental Art: A Visual Periodic Table

In this activity students will research an assigned element of the Periodic Table and then create a poster that visually explains and expresses the element. The final posters can be arranged into a classroom Periodic Table.
