Chemistry Periodic Table Trends Guided Inquiry Lesson

This student-centered, guided inquiry lesson enables students to construct their own understanding of common periodic trends including: valence electrons, energy levels, atomic radius, ionic radius, electronegativity, ionization energy, and properties of periodic table families. Students are able to actively learn the material without lecture or note taking.
