Classroom Resources: Energy & Thermodynamics
1 – 7 of 7 Classroom Resources
Identifying an Unknown, Mole Concept, Percent Composition, Emission Spectrum | High School
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.
Emission Spectrum, Electromagnetic Spectrum, Emission Spectrum, Electrons | High School, Middle School
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.
Interdisciplinary, Atomic Spectra, Identifying an Unknown, Emission Spectrum, Electromagnetic Spectrum, Emission Spectrum | Middle School, High School
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
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, Electromagnetic Spectrum, Emission Spectrum, Ions | High School
In this lab, students will investigate the colors produced when several mixtures of metallic ions are placed in a flame.
Interdisciplinary, Atomic Spectra, Identifying an Unknown, Emission Spectrum, Electromagnetic Spectrum, Emission Spectrum | High School, Middle School
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
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.
