In this emission spectra worksheet, students use a spectroscope to observe three types of spectra. These include continuous spectrum, emission spectrum and absorption spectrum.
Students contrast the different spectras. In this color and light lesson students explain the elements of emission spectra and match colors.
These attractive slides explain the basics of the electromagnetic spectrum and then display the emission spectra for a number of elements. argon, helium, hydrogen, xenon, neon and krypton are shown here and two graphs showing log scale of wavelengths and water vapor are given. The source links of these details are provided. A simple but useful resource for your students for research and element details.
Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.
In this chemistry lab worksheet, 11th graders identify the identity of the unknown element in the gas discharge tube and the identity of the unknown metal salt. Then, they describe how colors are produced by the two methods used in the lab. Finally, students imagine that they are forensic scientists given the task of identifying an unknown substance found at a crime scene. They select the method that would provide the most reliable results.
High schoolers investigate the wavelengths of spectra lines for common atoms. In this atomic emission spectra lesson plan, students use a transformer and diffraction grating to observe the emission spectra of various atoms. They find the wavelength, they calculate the energy for each spectral line and they use Rydberg's equation to calculate the electron transitions observed. High schoolers enter their data into a spreadsheet
Using spectroscopes, high school astronomy, physics, or chemistry learners observe emission spectra from several different sources. This stellar NASA-produced lesson plan provides terrific teacher's notes and a student handout. Make sure to check out other related lessons in the same "Imagine the Universe" series.
Students explain how an element can be identified using emission spectra. They relate the emission spectrum of hydrogen to its absorption spectrum and identify hydrogen absorption lines in the spectrum of stars.
Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be used when studying emission spectra in a chemistry or physics class. Note that you will need to rely solely on the student instructions as no teacher's notes are provided.
Students become familiar with the variables that control Earth's solar energy supply. They explore the source and nature of solar energy, the genesis of radiation, and the structrue of the Sun, gas spectra are observed and sample astronomical spectra are analyzed.
Designed by School Power...NaturallySM, this lesson familiarizes advanced earth science and physics learners about the variables that affect our supply of solar energy. They examine gas spectra and perform calculations. There is an abundance of learning to experience within the 24 pages of this resource!
Students demonstrate use of an Emission tube power supply, a diffraction grating, and a scientific calculator to determine the different wavelengths of light.
This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our universe. Each part consists of three to six lessons consisting of an online reading passage and related assignment. A hands-on activity is also provided for each section. As you would expect from NASA, this unit is out of this world!
Learners calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.
Students examine how to apply conservation of energy and properties of matter to a spectroscope. In this energy lesson students build their own spectroscope and observe three kinds of spectra.
Though there are technically only 13 questions on this exam, they take up six pages and make a thorough assessment of organic chemistry principles. There are plenty of diagrams to label or complete. Emission spectra are displayed for interpretation. Topics evaluated include valence bond theory, functional groups, chair conformations, acid base reactions, molecular geometry, and IUPAC names.
In this spectroscopy worksheet, students compare spectra produced by various light, they test metals using flame tests, they observe bright line spectra and emission spectra and determine unknown metals using flame tests and bright line spectra.
Four lessons make up this mini unit about atomic structure and spectra. A pretest is provided to give an idea of what is already known about the atom. Through a series of demonstrations and lecture, you present the information to young chemists. They construct a fruit model of the boron atom. They fill in a chart using the periodic table of elements. They compare and contrast two potatoes as an example of how isotopes are related. Asides from the dissection of a fried fish head, this is a terrific set of lessons for introducing the atom and radioactivty.
Slides and slides of emission spectra bring this topic to light for your physics class! Exited electrons returning to lower energy levels is offered as the cause of emission spectra. In summary, viewers learn that we can determine the composition of stars and how they are moving by examining their spectra. A bonus in this presentation is that there are a few slides of review questions interspersed throughout.
Learners examine the spectra of light sources that have similar colors. In this light lesson plan students complete an activity using various lights in the classroom and discuss the colors and the heat generated.
