New for the 2026-27 school year, 25x: Physical Science, Fifth Edition is a complete high school physical science workbook built for real classroom use.
This updated edition includes all-new articles, images, diagrams, IV/DV/Hypothesis activities, and Data Analysis activities designed to help students read, think, calculate, analyze, and apply science concepts with confidence.
Students explore the major foundations of physical science across 25 structured lessons, including measurement, matter, atomic structure, chemical reactions, forces, energy, magnetism, waves, electricity, astronomy, environmental science, geology, oceanography, Earth’s layers, and Earth’s atmosphere.
Each lesson is designed to move beyond memorization. Students read clear science articles, complete guided notes, analyze real-world scenarios, identify independent and dependent variables, interpret data tables, answer reflection questions, build vocabulary, and reinforce learning through crosswords and word searches.
This is the full version , including answer keys and teacher lecture notes , making it ideal for classroom instruction, independent study, review, intervention, homeschool use, and supplemental science practice.
