Subtest III: Physical Education; Human Development; Visual and Performing Arts
Science
What the questions test
Scientific inquiry: observation versus inference, hypothesis, controlled variables, repeated trials, data versus conclusion, and theory versus law. Physical science: properties of matter, states, density, atoms, mixtures and compounds, energy forms and transfer, forces and motion, simple machines, electricity and magnetism, and waves. Life science: cell structure and function, photosynthesis and respiration, heredity and DNA, natural selection, ecosystems, and energy flow and nutrient cycles. Earth and space science: rock types and the rock cycle, plate tectonics, weathering and erosion, the water cycle, weather versus climate, the Earth-Sun-Moon system, and the solar system.
Traps
Mass versus weight; observation versus inference; hypothesis (testable prediction) versus theory (well-supported explanation). Confusing weathering (breakdown in place) with erosion (transport). Confusing weather with climate. A persistent misconception is that plants get their food from soil - they make it by photosynthesis. Also watch misread graph axes and unit labels.
Worked example
Two identical plants receive 50 mL and 100 mL of water daily. Water amount is the independent variable, plant growth the dependent variable, and light, soil, and pot size are constants. Rule of thumb: change one thing, measure one thing, hold everything else the same.
Physical Education
What the questions test
Health-related fitness components: cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition. Skill-related components: agility, balance, coordination, power, reaction time, and speed. The FITT principle (frequency, intensity, time, type), plus overload, progression, specificity, and reversibility. Also motor development stages, fundamental movement skills (locomotor, non-locomotor, manipulative), biomechanics (levers, force, balance, center of gravity), sport-specific tactics, safety and injury prevention, inclusion and adaptive physical education, and assessment through formative checks and fitness testing.
Traps
The most frequent error is mixing health-related and skill-related components. Stretching is not a warm-up; a warm-up raises body temperature and rehearses movement. Target heart rate is individual, based on age or measured maximum, not a single class number. Muscular strength is maximal force; muscular endurance is repeated contractions over time.
Worked example
A 30-year-old wants moderate aerobic activity. Estimated maximum heart rate is 220 − 30 = 190 bpm; the moderate zone is about 50–70%, or roughly 95–133 bpm. Applying FITT: five days per week, moderate intensity, 30 minutes, jogging. Rule of thumb: FITT answers how often, how hard, how long, and what kind.
Human Development
What the questions test
Physical, cognitive, language, and social-emotional development across the lifespan. Piaget: sensorimotor (object permanence), preoperational (symbolic play, egocentrism, lack of conservation), concrete operational (conservation, classification), formal operational (abstract reasoning). Vygotsky: zone of proximal development, scaffolding, social origins of learning. Erikson's psychosocial stages, Kohlberg's moral reasoning, Bronfenbrenner's ecological systems, Ainsworth's attachment patterns, Baumrind's parenting styles, and stages of language acquisition. Also brain development, adolescent development, and distinguishing typical from atypical development.
Traps
Misassigning a behavior to the wrong stage - conservation belongs to concrete operational, not preoperational. Confusing Piaget's constructivism with Vygotsky's emphasis on social interaction. Mixing Erikson's stage names or their order. Conflating physical growth with cognitive readiness.
Worked example
A child insists a tall narrow glass holds more water than a short wide one even after pouring back and forth. This is failure of conservation, the hallmark of the preoperational stage, roughly ages two to seven. Rule of thumb: identify the cognitive task first (conservation, object permanence, abstract reasoning), then name the theorist and stage.
Visual and Performing Arts
What the questions test
Visual art elements: line, shape, form, color, value, texture, and space. Principles of design: balance, contrast, emphasis, movement, pattern, rhythm, unity, and proportion. Color theory: primary and secondary colors, warm and cool, complementary (opposite on the wheel), analogous (adjacent). Dance elements: body, space, time, and energy, plus locomotor and non-locomotor movement. Music elements: melody, rhythm, harmony, texture, form, timbre, dynamics, and tempo. Theatre: acting, directing, script, design, and audience. Also arts integration, the artistic processes of creating, performing, responding, and connecting, and the role of the arts in child development.
Traps
The classic error is confusing elements (the ingredients) with principles (how they are arranged). Complementary versus analogous colors is another frequent mix-up, as is steady beat versus rhythm. In music, form is structure (ABA, rondo) while genre is style. Do not assume arts integration means replacing sequential arts instruction.
Worked example
Red and green sit opposite each other on the color wheel, so they are complementary and create high contrast; red, red-orange, and orange sit side by side, so they are analogous and create harmony. Rule of thumb: elements are what you use, principles are how you use them.
