  Electromagnetic Spectrum, Emission Spectrum, Emission Spectrum, Electrons | Middle School, High School

  Lesson Plan: Let it Glow Mark as Favorite (38 Favorites)

  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.

• 

  Electromagnetic Spectrum, Molecular Structure, Mixtures | Middle School, High School

  Video: What are Pigments? Video Mark as Favorite (14 Favorites)

  This video discusses the chemistry of pigment molecules and how they are used to give paints their specific color. Students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.

• 

  Mixtures, Solute & Solvent, Intermolecular Forces, Intermolecular Forces, Molecular Formula, Molecular Structure, Polymers, Electromagnetic Spectrum | Middle School, High School

  Video: What is Paint? Video Mark as Favorite (17 Favorites)

  This video investigates the composition of paint, while analyzing the fundamental chemistry principles of its main components. Students will learn about the differences between three common paint types, water colors, oil-based and acrylic paint as well as the chemistry of each.

• 

  Electromagnetic Spectrum | High School

  Activity: Electromagnetic Spectrum Book Mark as Favorite (37 Favorites)

  In this activity, students will create a book that describes all of the individual parts that make up the electromagnetic spectrum.

• 

  Atomic Spectra, Emission Spectrum, Emission Spectrum, Electromagnetic Spectrum, Interdisciplinary, Identifying an Unknown | Middle School, High School

  Lab: Spectral Detective Mark as Favorite (33 Favorites)

  In this lab, students will use a spectroscope to view the atomic spectra of various unknown elements. Using their collected data in combination with known atomic spectra, they will identify the chemical elements.

• 

  Radiation, Electromagnetic Spectrum, Radiation | Middle School, High School

  Lab: The Most Effective Sunscreen Mark as Favorite (27 Favorites)

  In this lab, students will research and compare the effectiveness of various SPF levels in sunscreen lotions. The lotion’s ability to block UV (ultraviolet) radiation from the sun will be tested using a UV bead detector.    

• 

  Atomic Spectra, Activity Series, Emission Spectrum, Ions, Electromagnetic Spectrum, Emission Spectrum, Observations, Inferences | High School

  Lab: Flame Test: Going Further Mark as Favorite (57 Favorites)

  In this lab, students will investigate the colors produced when several mixtures of metallic ions are placed in a flame.

• 

  Atomic Theory, Law of Conservation of Energy, Electrons, Electromagnetic Spectrum | High School

  Activity: Simulation Activity: Exciting Electrons Mark as Favorite (90 Favorites)

  In this simulation, students will explore what happens when electrons within a generic atom are excited from their ground state. This is a qualitative investigation, not meant to mimic any particular atom.

• 

  Separating Mixtures, Interdisciplinary, Electromagnetic Spectrum, Mixtures, Mixtures | Middle School

  Lab: Candy and Leaf Chromatography Mark as Favorite (13 Favorites)

  In this lab, students will learn that mixtures are created by the combination of two or more substances. Many colors are actually mixtures of several different pigments. Mixtures can be separated, and in this lab students will perform chromatography to separate mixtures found in candy and in leaves.

• 

  Atomic Spectra, Emission Spectrum, Emission Spectrum, Electromagnetic Spectrum, Interdisciplinary, Identifying an Unknown | Middle School, High School

  Lab: Build a Spectroscope Mark as Favorite (24 Favorites)

  In this lab, the students will make and use a spectroscope to identify the spectra within various types of light bulbs. The students will then develop an improved design for the spectroscope.

• 

  Emission Spectrum, Emission Spectrum, Electromagnetic Spectrum, Subatomic Particles, Electrons, Atoms, Atomic Theory, Model of the Atom | High School

  Lesson Plan: Modeling Energy in Chemistry: Energy and the Electron Mark as Favorite (64 Favorites)

  This activity is designed for students to build a scientific argument about the relationship between energy and spectral lines by exploring how light interacts with atoms. In the process, students will examine proposed models of the hydrogen atom and use collected data to analyze the proposed models. They will then select one of the models and write a scientific argument to support their choice. Students will then review additional data to support and/or refute their selection. Based on their analysis, students will revise their selected model and construct a new argument to support their revisions.

  Atomic Theory, Law of Conservation of Energy, Electrons, Electromagnetic Spectrum | High School

  Simulation: Exciting Electrons Mark as Favorite (59 Favorites)

  In the March 2015 issue, students explore what happens when electrons within a generic atom are excited from their ground state. They will see that when an electron relaxes from an excited state to its ground state, energy is released in the form of electromagnetic radiation.
