Action Science Physical Science

The curriculum covers comprehensive physical science content systematically across four units. Topics include atomic structure, periodic table, energy, motion, and waves with substantive content knowledge built through each lesson.

Units systematically cover 'physical and chemical properties, mixtures, solutions, atomic structure, the periodic table, elements, and compounds' and other core topics as outlined in detailed unit descriptions

The curriculum explicitly aligns with current science standards and covers required content comprehensively. All middle school physical science requirements are addressed across the four units.

Review states the units 'cover all of the middle-school physical science requirements as laid out by the National Academy of Sciences K-12 Science Framework and the Next Generation Science Standards'

The curriculum strongly integrates hands-on activities with content instruction through structured experiments in each unit. Lab activities are designed to reinforce concepts being taught rather than pure discovery.

Each lesson may include 'an experiment or activity' with 'instructions, record-keeping charts for students to record observations, and questions to help students analyze their results'

The curriculum explicitly teaches scientific vocabulary with clear presentation methods. Key terms are highlighted and defined systematically throughout the units.

Review notes 'Vocabulary words are in bold, and their definitions are in sidebars' showing explicit vocabulary instruction

Teacher guides provide basic support including answer keys and supply lists, but appear to offer limited pedagogical guidance or science content background for teachers. Support is practical rather than comprehensive.

Teacher guides have 'brief information about the units and how to use them, a chart showing supplies needed for each lesson, and occasional notes with additional information' plus 'complete answer keys'

The curriculum appears to balance direct instruction with inquiry, providing clear explanations alongside hands-on activities. Content is presented in an accessible way for independent learning.

Lessons include 'text with occasional illustrations, photos, or charts' and 'the style of writing and the content should be easy for students working independently to understand'

The curriculum includes practice problems and review activities but lacks systematic retrieval practice or spaced review systems. Assessment relies mainly on ongoing activities rather than formal recall exercises.

Includes 'practice problems' that 'might involve definitions of vocabulary words, critical thinking, applications of lesson content, or mathematical calculations' but 'there are no tests'
