- Photosynthesis
- Related: Symbiosis, Greenhouse effect
The process by which green plants, algae, and some bacteria use sunlight, water, and carbon dioxide to make sugar, releasing oxygen as a by-product.

- Plate tectonics
- Related: Greenhouse effect
The theory explaining that Earth's outer shell is broken into large moving slabs whose collisions, spreading, and sliding cause earthquakes, volcanoes, mountain building, and the drift of continents.
- Greenhouse effect
- Related: Photosynthesis, Plate tectonics
The warming of Earth's surface that occurs when certain gases in the atmosphere trap heat radiating from the ground, keeping the planet habitable but intensifying with added emissions.
- Inflation
A sustained rise in the general level of prices across an economy, which reduces the amount of goods and services a given sum of money can buy.

- Quadratic equation
- Related: Measures of central tendency

- Measures of central tendency
- Related: Quadratic equation
Summary values-mean, median, and mode-that describe the typical or middle score of a data set; each is chosen according to the data's shape and level of measurement.
- Constructivism
- Related: Zone of proximal development, Scaffolding, Metacognition
A learning theory holding that learners build new understanding by connecting new information to what they already know, so teaching should provide experiences and questions rather than only transmitted facts.
- Behaviorism
- Related: Constructivism
A theory that treats learning as a change in observable behavior produced by stimuli, reinforcement, and punishment, with little attention to internal mental processes.
- Zone of proximal development
- Related: Scaffolding, Constructivism
The gap between what a learner can do alone and what the learner can accomplish with guidance from a more capable person; instruction is most effective when aimed at this range.
- Scaffolding
- Related: Zone of proximal development, Differentiated instruction
Temporary support-such as prompts, models, or step-by-step guides-given to a learner during a task and gradually withdrawn as competence grows.
- Bloom's taxonomy
- Related: Table of specifications, Formative assessment
A hierarchical classification of learning objectives in the cognitive domain, moving from remembering and understanding through applying and analyzing to evaluating and creating.
- Formative assessment
- Related: Summative assessment, Rubric
Ongoing, low-stakes checks of student understanding during instruction, used mainly to adjust teaching and give feedback rather than to assign a final grade.
- Summative assessment
- Related: Formative assessment, Table of specifications
An evaluation given at the end of a unit, term, or course to judge how much learning has occurred, usually reported as a grade or score for accountability.
- Differentiated instruction
- Related: Scaffolding, Inclusive education
Planning lessons so that content, process, product, or learning environment are adjusted to fit students' readiness, interests, and learning profiles within the same classroom.
- Rubric
- Related: Formative assessment, Summative assessment
A scoring guide that lists the criteria for a task and describes levels of quality for each criterion, making grading more consistent and understandable to students.
- Individualized Education Program
- Related: Inclusive education, Differentiated instruction
A written plan required for a learner with a disability, specifying present levels of performance, measurable goals, services, accommodations, and how progress will be monitored.
- Metacognition
- Related: Constructivism, Formative assessment
Awareness and regulation of one's own thinking-knowing what one understands, planning an approach, monitoring progress, and adjusting strategies when comprehension breaks down.
- Table of specifications
- Related: Bloom's taxonomy, Reliability
A test blueprint that maps test items to learning objectives and content areas and sets the number or weight of items for each, helping ensure balanced content coverage.
- Reliability
- Related: Table of specifications
The consistency of a test or measurement-whether it yields similar results when repeated, scored by different raters, or made up of comparable items.
- Spiral progression
- Related: Bloom's taxonomy
A curriculum design that revisits key concepts across grade levels with increasing depth and complexity, so earlier learning is reinforced and extended rather than abandoned.
- Inclusive education
- Related: Individualized Education Program, Differentiated instruction
The practice of educating learners with disabilities and other diverse needs in regular classrooms with appropriate support, rather than segregating them in separate settings.
- Phonics
- Related: Context clues, Reading fluency
An approach to teaching reading that links letters and letter patterns to the sounds they represent, helping beginners decode unfamiliar printed words.
- Context clues
- Related: Reading fluency, Main idea
Hints about an unfamiliar word's meaning supplied by the surrounding sentence or passage, such as a definition, example, contrast, or cause-and-effect relationship.
- Reading fluency
- Related: Phonics, Context clues
The ability to read text accurately, at an appropriate rate, and with suitable expression, which frees attention for comprehending what is read.

- Related: Quadratic equation
The value assigned to a digit based on its position in a numeral, so in 4,582 the 5 stands for five hundreds rather than five ones.
- Scientific method
- Related: Primary source
A systematic procedure for investigating questions: observing, forming a testable hypothesis, experimenting or gathering data, analyzing results, and drawing conclusions that may later be revised.
- Primary source
- Related: Scientific method
An original document, artifact, recording, or eyewitness account created during the period under study, used as direct evidence rather than as a later interpretation.
