For this electromagnetic radiation and atomic structure worksheet, students answer thirteen questions about topics such as wavelength, frequency and the electromagnetic spectrum. They also answer questions about the location of electrons using the Bohr model of the atom and the quantum mechanical model of the atom.
High schoolers explore the nature of electromagnetic spectrum through a series of experiments. In this physics lesson, students determine how light behaves under certain circumstances. They explain how humans perceive colors.
In this chemistry worksheet, students study the Bohr atomic model and calculate the wavelength and frequency of given electromagnetic radiation. They answer 9 problems and short answer questions.
This short slide show applies the electromagnetic spectrum to astronomy. First, electromagnetic radiation is introduced to viewers. Wavelength is defined and its unit of measurement explained. Finally, aspiring astronomers find that the electromagnetic spectra given off by a star can provide its composition, temperature, and more!
The idea of whether or not communication from other planets can be transmitted and received is discussed in this presentation. The various issues such as relative stages of development, the ability to receive a transmission, and whether any possible signal has been sent in our direction are discussed.
Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic process. Each part includes background reading, a hands-on inquiry activity, and critical thinking questions to answer. If you have been teaching science for a while, the activities will be familiar to you, but the detailed explanations and student resources are a tremendous bonus!
Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After observing a box of water and creating waves in the water to observe the relationship between energy and wavelength, they observe a light shining on a prism and record their observations.
Four modules are a part of this stellar lesson plan. Space scientists view the electromagnetic spectrum, they generate waves on a computer screen in order to measure frequency and wavelength, discover how light is related to temperature, and finally relate their learning to the temperature of stars. Much of this instructional activity is taught via an interactive website. There is so much terrific material here that you could spend an entire week on this topic!
Students engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.
Students explore the infrared radiation and the part of the spectrum that is not always visible.  In this electromagnetic lesson students complete a lab activity on the different wavelengths.
Students explore energy by conducing a science experiment in class. In this electricity activity, students identify the parts of an electrical generator and explain how energy is created. Students utilize magnetic materials and copper wires to create an electric generator.
Students define electromagnetic radiation, list major categories and uses of electromagnetic waves, identify potential health risks with electromagnetic waves, and demonstrate understanding of Plank's constant by solving quantitative equations on wavelength, frequency, and energy.
Students explain how electricity is transferred from source to load without actual wires connecting the two. In this physics lesson, students explore how wireless electricity was discovered. They cite practical applications of this technology.
In this atomic spectra worksheet, students answer eighteen questions about wavelengths of light, the emission spectrum, energy of photons, the frequency of electromagnetic radiation and electrons in the excited state.
Students examine the basics of luminous efficacy and why it is used.  In this light source lesson students test energy efficiency and the luminous efficiency for babies.
As the title implies, here is a collection of typical photoelectric effect problems that physics learners need to be able to solve. They determine the amount of energy of a photon, the photons produced per second, the frequency required for work functions, and more. There are multiple choices to choose from for the answers, which will help beginning photoelectric physicists make sure they are on the right wavelength!
Your high schoolers examine various types of electromagnetic waves and create a chart of the spectrum. They watch a video segment and use an interactive activity that explains the range of the spectrum and common sources of electromagnetic waves.
Ninth graders complete several demonstrations and investigations related to the different regions of the electromagnetic spectrum. They develop a flip-book regarding the electromagnetic spectrum to document their achievement.
Ninth graders investigate light as waves and view evidence of the types of light waves. They discuss the wave energy and wavelength of the various types of light.
Students acquire information about the electromagnetic spectrum. They explore how its interpretation enables scientists to gather information about the universe.
