The Guest Investigator Puzzle

In this measuring star temperatures, students find the temperature of a star using Planck's curve and the Wein Displacement law. Students also find the peak wavelengths for given stars using Planck's curve.

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

It takes 225 million years for our sun to travel around the galaxy. The presentation covers astronomical units, light years, telescopes, types of stars, the life cycle of a star, and types of galaxies. This is the last lesson in a...

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...

Star light, start bright! What do the brightness and color of stars tell us about the stars we see at night? Learners explore the life of stars with an information-packed video. Topics include the relationship between mass and...

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...

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...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

High schoolers practice manipulating algebra formulas with more than one variable. They examine the topics of velocity, wavelength and frequency. They determine the amount of red-shift in a receding star.

Part of a larger online space science website, this page has a brief explanation of electromagnetic radiation and a chart of wavelengths as compared to common objects. There are four questions to answer about the information. This can be...
