Knowledge and Skills Statement

Science concepts. The student knows that changes in matter affect everyday life.

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.

The coefficients in a balanced chemical reaction indicate how many of each substance is used or produced when the reaction proceeds to completion. The coefficient is multiplied by the subscript to determine the quantity of each element.

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.

substance that occupies space, has mass, and is composed of microscopic particles

Research

Bílek, Martin, Małgorzata Nodzyńska, Wioleta Kopek-Putała, and Paulina Zimak-Piekarczyk."Balancing Chemical Equations Using Sandwich Making Computer Simulation Games As A Supporting Teaching Method." Problems of Education in the 21st Century 76, no. 6 (2018): 779-799. https://doi.org/10.33225/pec/18.76.779

Summary:  The aim of the research was to examine whether using computer simulations can help younger children to balance chemical equations before they start to learn chemistry by using the psychological theory of transfer. The obtained results proved that the balancing of the simple equation of reaction was mastered by over 50% of the children tested.
