STAAR Grade 8 Science Reference Materials - Periodic Table

Sep 30, 2026

STAAR Grade 8 Science reference materials for Texas Assessments of Academic Readiness, centered on core physics formulas and a comprehensive periodic table layout. Includes key relationships such as density, average speed, and net force, alongside atomic numbers, element symbols, and atomic masses for many elements. Also lists lanthanide and actinide series with element names and values, and notes that atomic masses are omitted for elements without stable or common isotopes.
