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!
In 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.
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!
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 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 lesson is taught via an interactive website. There is so much terrific material here that you could spend an entire week on this topic!
Students explore energy by conducing a science experiment in class. In this electricity lesson, 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.
A combination of informative text, photos, and graphics comprise this sharp show on electromagnetic radiation. Some slides mention hands-on activities for demonstrating concepts, so if you want to include them you will need to figure out a procedure and materials (not explicitly described). Because this explains electromagnetic radiation in terms of photons and explains the mathematical formula for wavelengths, it may be most appropriate for middle school or high school physical science learners.
