Overview

Knowledge and Skills Statement

Science concepts. The student knows that relationships exist between the structure and properties of matter.

Glossary Support for IPC.7.B

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.

chemical property	a characteristic of a particular substance that can be observed during or after a chemical reaction; a quality that can be established only by changing a substance's chemical identity
matter	substance that occupies space, has mass, and is composed of microscopic particles
periodic table	an organizational chart of all the known elements on Earth, organized based on the physical and chemical properties of each
physical property	observable characteristic of matter that can be used to identify particular materials
property	characteristic of matter that can be used to identify particular materials
structure	something arranged in a definite pattern of organization; the arrangement of particles or parts in a substance or body; the aggregate of elements of an entity in their relationships to each other

Summary: The Periodic Table shows patterns in the chemical properties of elements. Elements were originally grouped into triads by similarity. Scientists then realized that elements could be a part of two different triads and be compared in two directions. Mendeleev’s system recognized a pattern in the property of elements. This article explains the history and progression of the Periodic Table and how its pattern can be used to predict the properties of elements.

Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

TEKS Level	Standard
S.1.6.A	classify objects by observable physical properties, including, shape, color, and texture, and attributes such as larger and smaller and heavier and lighter;
S.2.6.A	classify matter by observable physical properties, including texture, flexibility, and relative temperature, and identify whether a material is a solid or liquid;
S.3.6.A	measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float in water;
S.3.6.B	describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container;
S.4.6.A	classify and describe matter using observable physical properties, including temperature, mass, magnetism, relative density (the ability to sink or float in water), and physical state (solid, liquid, gas);
S.5.6.A	compare and contrast matter based on measurable, testable, or observable physical properties, including mass, magnetism, relative density (sinking and floating using water as a reference point), physical state (solid, liquid, gas), volume, solubility in water, and the ability to conduct or insulate thermal energy and electric energy;
S.6.6.A	compare solids, liquids, and gases in terms of their structure, shape, volume, and kinetic energy of atoms and molecules;
S.6.6.C	identify elements on the periodic table as metals, nonmetals, metalloids, and rare Earth elements based on their physical properties and importance to modern life;
S.6.6.D	compare the density of substances relative to various fluids; and
S.8.6.C	describe the properties of cohesion, adhesion, and surface tension in water and relate to observable phenomena such as the formation of droplets, transport in plants, and insects walking on water;
S.8.6.D	compare and contrast the properties of acids and bases, including pH relative to water; and
IPC.7.B	use patterns within the Periodic Table to predict the relative physical and chemical properties of elements;
CHEM.5.A	explain the development of the Periodic Table over time using evidence such as chemical and physical properties;
CHEM.5.B	predict the properties of elements in chemical families, including alkali metals, alkaline earth metals, halogens, noble gases, and transition metals, based on valence electrons patterns using the Periodic Table; and
IPC.7.C	explain how physical and chemical properties of substances are related to their usage in everyday life such as in sunscreen, cookware, industrial applications, and fuels;
CHEM.12.B	define acids and bases and distinguish between Arrhenius and Bronsted-Lowry definitions;
CHEM.12.C	differentiate between strong and weak acids and bases;
CHEM.12.E	define pH and calculate the pH of a solution using the hydrogen ion concentration.
AQUA.5.B	identify how aquatic ecosystems are affected by water's properties of adhesion, cohesion, surface tension, heat capacity, and thermal conductivity; and

Breakout of Skills

Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.
