1 – 8 of 8 Classroom Resources

• 

  Elements, Identifying an Unknown, Atomic Spectra, Emission Spectrum, Electromagnetic Spectrum, Emission Spectrum | Middle School, Elementary School

  Lesson Plan: Elements Are Out of This World Mark as Favorite (1 Favorite)

  In this lesson, students will learn about the elements that make up Earth’s atmosphere and lithosphere and then compare and contrast the information with the elements that compose various other astronomical objects.

• 

  Percent Composition, Mole Concept, Identifying an Unknown, Emission Spectrum | High School

  Lesson Plan: Chemical Analysis of Martian Rocks Mark as Favorite (32 Favorites)

  In this lesson, students are challenged to analyze the spectral graphs obtained by the Curiosity Mars Rover. Based on their examination students will determine the component elements of each sample, as well as the relative abundance of each element. With this information the student will complete calculations to find the empirical formula and identify the composition of the unknown rock. Finally students will complete research to see if these rocks are actually like those on Earth.

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

  Lesson Plan: Let it Glow Mark as Favorite (12 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.

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

  Lab: Spectral Detective Mark as Favorite (14 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.

• 

  Emission Spectrum, Electromagnetic Spectrum | High School

  Demonstration: The Emission Spectrum from a Candle Flame Mark as Favorite (1 Favorite)

  In this demo, students look at a candle flame through a diffraction grating to see the emission spectrum of the flame. This provides for an opportunity to talk about how a flame works and prove that carbon is being released by charring a porcelin crucible.

• 

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

  Lab: Flame Test: Going Further Mark as Favorite (22 Favorites)

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

  Lab: Build a Spectroscope Mark as Favorite (8 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 | High School

  Lesson Plan: Modeling Energy in Chemistry: Energy and the Electron Mark as Favorite (16 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.
