Science Casts: Mysterious Objects at the Edge of the Electromagnetic Spectrum

Lead your class in a fun-filled team activity that encourages collaboration while learning important concepts. Pupils actively participate in a discussion on the experimental design and the role of mirrors. They perform group activities...

Do you have blossoming astronomers who seek to understand the electromagnetic spectrum? Assist them with exploring electromagnetic radiation and the electromagnetic spectrum as the class conducts various activities to demonstrate...

Science learners scrutinize shadow size and quality, and experiment with diffraction. They model superposition of electromagnetic waves, and experiment with interference. These activities are action-packed and challenging for your...

A discussion of radio waves and the electromagnetic spectrum starts an innovative lesson about wavelengths. Then, a guided practice problem on how to convert kHz to wavelength gets pupils on the right track. Finally, they solve a...

What can the electromagnetic spectrum tell us about the sun? As it turns out, quite a bit! See the sun in a whole new light with a video from NOVA's Sun Lab unit. The narrator describes the electromagnetic spectrum in terms of visible...

Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers,...

An article that discusses the coupling of an electric field with a magnetic field to create electromagnetic waves. Article also discusses how different types of electromagnetic waves have different wavelengths which forms the...

Examine the concept of an electromagnetic spectrum with your students, as they observe a demonstration of a model, construct and compare a different model of the spectrum commonly used in textbooks, and construct their own models of the...

Scholars relate each of the colors in the spectrum, except indigo, by comparing their frequencies, wavelengths, and energy levels. Then, they compare each section of the electromagnetic spectrum when considering the same three variables.

Learn about the coupling of an electric field with a magnetic field to create electromagnetic waves in this video. Video also discusses how different types of electromagnetic waves have different wavelengths which forms the...
