Classroom Resources: Energy & Thermodynamics

26 – 28 of 28 Classroom Resources

• 

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

  Lab: Build a Spectroscope

  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.

• 

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

  Lesson Plan: Modeling Energy in Chemistry: Energy and the Electron

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

  Simulation: Exciting Electrons

  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.
