STAAR Grade 8 Science Study Guide 2026–2027 | TEKS-Aligned Review + 200 Practice Questions | Printable PDF

A complete study guide for the STAAR Grade 8 Science test (now called the Middle School STAAR Science test), organized by the four strands in the Texas Education Agency blueprint and covering the tested Grade 6, Grade 7, and Grade 8 science standards.

What's Inside:

• Matter and Energy: classifying matter, density, the periodic table, counting atoms in chemical formulas, physical and chemical changes, and conservation of mass (including photosynthesis)
• Force, Motion, and Energy: net force, Newton's laws and F = ma, speed and velocity, distance-time graphs, energy conservation, thermal energy, and waves and the electromagnetic spectrum
• Earth and Space: Earth's layers, plate tectonics, evidence of Earth's changes, watersheds and oceans, gravity, seasons, tides, stars and the H-R diagram, galaxies, weather, climate, global winds, and hurricanes
• Organisms and Environments: cell theory and cell structures, human body systems, ecosystems and biodiversity, energy pyramids, ecological succession, adaptations, natural and artificial selection, genes, and reproduction
• Science and engineering practices: variables, tools, data, calculations, models, and short constructed responses
• 2 practice tests with 200 STAAR-style questions built on investigations, data tables, graphs, diagrams, and calculations
• Detailed answer explanations for every question
• Exam overview, 4-, 8-, and 12-week study schedules, and strategies for calculations and the newer question types
• Diagrams, worked examples, and tables for quick review
