Classroom Resources: Energy & Thermodynamics
26 – 32 of 32 Classroom Resources
-
Atomic Spectra, Emission Spectrum, Emission Spectrum, Electromagnetic Spectrum, Interdisciplinary, Identifying an Unknown | Middle School, High School
Lab: Spectral Detective
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
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
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
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
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
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
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.
