What you can see at the bottom is a complex literature query. To an astronomer, “abundance” means the fraction of different elements in a star. It is also called metallicity. The next image is what it looks like today. It is basically the same query, except that we have changed the word abundance to metallicity.

As of 2013, the National Science Education Standards have been replaced by the Next Generation Science Standards (NGSS), available as a print book, free PDF download, and online with our OpenBook platform.
The NGSS offer a detailed description of the key scientific ideas and practices that all students should learn by the time they graduate from high school. The standards are based largely on the 2011 National Research Council report A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas.
