The Guest Investigator Puzzle

Students study about the different types of UV rays and how they can protect themselves against their harmful effects. They explain how to interpret the UV index in order to plan the best time to participate in outdoor activities

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...

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...

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...

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,...

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...
