Knowledge and Skills Statement

Science concepts. The student understands and applies various rules regarding acids and bases.

The further explanation is designed to be a resource for educators that helps them better understand the topic their students are learning. Further explanations may be written at a more complex level than would be expected for students at the grade level.

For example:
Vinegar is the common English name for acetic acid, CH3OOH.
Caffeine is the common English name for 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione.  

The IUPAC name encodes the structure and composition of the molecule and allows a chemist to unambiguously reference the molecule.

Glossary terms and definitions are consistent across kindergarten through high school in the TEKS Guide. The definitions are intended to give educators a common understanding of the terms regardless of what grade level they teach. Glossary definitions are not intended for use with students.

any substance that in aqueous (water) solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, promotes chemical reactions (acid catalysis), and has a pH less than 7

any substance that in aqueous (water) solution is slippery to the touch, tastes bitter, changes the color of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, promotes certain chemical reactions (base catalysis), and has a pH greater than 7

Research

Buendía-Atencio, Cristian, Gilles Paul Pieffet, and Vaneza Paola Lorett Velásquez. "WERNER: A Card Game for Reinforcement Learning of Inorganic Chemistry Nomenclature." Journal of Chemical Education 99, no.5 (2022): 2198. https://doi.org/10.1021/acs.jchemed.2c00166

Summary:  Identifying and naming inorganic compounds is sometimes a challenge for many first-year chemistry and engineering students; however, these difficulties can be overcome after extensive practice using homework sets based on naming inorganic compounds or applying inorganic nomenclature rules. In the classroom, a card game was used immediately after explaining the basic nomenclature rules. Overall, the students found the game engaging and enjoyable, and they responded favorably to its use as an educational didactic tool.
