Scope on the Skies: Living with a starby: Bob Riddle

Journal ArticleDigital resources are stored online in your NSTA Library.

Currently, our Sun is a content, middle-aged main sequence star steadily fusing hydrogen atoms into helium atoms and releasing radiation in many of the wavelengths making up the electromagnetic spectrum. So what happens between now and when the Sun runs out of hydrogen? And what happens after that? Before we can answer these questions, we need to take a look at what goes on within a star’s hot interior and how that energy reaches the surface of the Sun and then onward out into the surrounding space.

I have taught about the sun and read about the sun and I thought I understood about its layers. I have to say that this was probably the easiest explanation I have read about how the inner layers differ from each other and I learned a lot from reading this short informative article. I liked the suggested modeling activities to help students understand how the photons move through the radiative zone too, it helped me to picture the process much more clearly.

When you ask middle school students how many stars in our solar system, they often say billions. Then they learn that there is only one, our Sun. This article is all about our only star in our solar system. From its very center to its outer surface you learn all about the midsized star. A great deal is constantly going on in the huge ball of gases. Reading this article provides insight to why it provides us light and heat energy as well as producing solar winds.
