Title: Lesson Plans Page
Description: This website has lessons for distinguishing between solids, liquids and gases.
Standard(s):
[S1] PHS (9-12) 5: Describe physical and chemical changes in terms of endothermic and exothermic processes.

Title: It's Elemental - The Periodic Table of Elements
Description: This site provides a printable periodic table with information on each element, interactive games, puzzles, and activities.
Standard(s):
[S1] PHS (9-12) 1: Recognize periodic trends of elements, including the number of valence electrons, atomic size, and reactivity.
[S1] PHS (9-12) 3: Contrast the formation of ionic and covalent bonds based on the transfer or sharing of valence electrons.
[S1] PHS (9-12) 4: Use nomenclature and chemical formulas to write balanced chemical equations.
[S1] PHS (9-12) 5: Describe physical and chemical changes in terms of endothermic and exothermic processes.
[S1] CHE (9-12) 3: Use the periodic table to identify periodic trends, including atomic radii, ionization energy, electronegativity, and energy levels.
