26 – 33 of 33 Classroom Resources

• 

  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 (56 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.

• 

  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 (58 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.
