Unraveling the Mysteries of Objects in Space

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...

Saturn's rings are made of dust, ice, and solid chunks of material. Individuals use spectrographs in this final installment of 22 lessons to determine the atmospheric elements. They analyze spectrums from Titan's atmosphere and Saturn's...

Look beyond the light! An engaging activity introduces young scholars to the application of a spectroscope. The lesson is the fifth in a series of six and focuses on the analysis of the elements of the sun.

Students examine the spectra of light sources that have similar colors.  In this light instructional activity students complete an activity using various lights in the classroom and discuss the colors and the heat generated. 

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...

In this activity, students make simple spectroscopes (prisms) to look at different light sources. The spectroscopes allow students to see differing spectral distributions of different light sources.

Students create spectral colors. For this hands-on science lesson, students examine the electromagnetic spectrum as they follow steps to create a model that separates and displays light.

Students investigate the electromagnetic spectrum, focusing on visible light. They are introduced to the idea that all light travels as waves, and that wavelength defines the various regions of the electromagnetic spectrum.

Young scholars indentify whether an objects reflects or absorbs red, green, and/or blue light. They create a simple spectral signature.

Students demonstrate use of an Emission tube power supply, a diffraction grating, and a scientific calculator to determine the different wavelengths of light.
