How Many Protons, Neutrons, and Electrons Are in Common Elements?

This site, part of Exploring Earth Investigation by McDougal Littell and TERC, examines how many protons, neutrons, and electrons are in common elements. The investigations "were designed to build students' knowledge of Earth Science concepts�and to raise student awareness of Earth as a system of interconnected components and processes." Here, visitors can find lessons on common elements, elements in a penny, atomic models, Bohr's atomic model (where you can build an atom yourself), and reading the periodic table. Many sections have illustrative images and interactive features, which help students, understand the topics presented, and the final section ends with questions for students to further explore as well as a link to an online version of the periodic table of elements. This is an excellent site for any Earth Science classroom as an introductory lecture or as an out-of-class exploration for students.
