Human Body Systems and Sensory Organs

Classify materials by observable properties, test their physical traits, and build complex structures from smaller interchangeable units.

Differentiate between reversible state changes and irreversible physical alterations through heating, cooling, and mechanical forces.

Investigate atmospheric and fluid phenomena including air volume, surface tension, buoyancy, and solution separation.

Investigate how balanced and unbalanced contact forces, friction, collisions, and gravity alter the motion and shape of objects.

Explain how vibrating matter produces sound, propagates through media, and how vibration rate and size govern pitch and volume.

Investigate straight-line light propagation, shadow formation factors, reflection from flat mirrors, and refraction through lenses and water.

Investigate thermal conduction, temperature balance, and design thermal barriers to slow heat loss.

Test magnetic poles and orientation, explore static charges, build complete electric circuits, and classify electrical conductors.

Identify plant organs, investigate water and nutrient transport, examine flower reproduction, and determine seed germination requirements.

Classify vertebrates into five major groups, contrast vertebrate traits with invertebrates, and model diverse animal life cycles.

Examine major invertebrate groups, explore fungi roles as decomposers, and investigate helpful and harmful microorganisms.

Investigate human organ systems, test sensory responses, and measure physiological indicators like pulse and breathing rates.

Evaluate nutrition balance, dental health, handwashing hygiene, sensory protection, and disease transmission defenses.

Construct food chains with producers, consumers, and decomposers, trace solar energy flow, and analyze habitat interdependence.

Explain structural and behavioral adaptations, analyze animal-plant mutualism in pollination, and compare seed dispersal mechanisms.

Recognize inherited traits, compare individual variations, and analyze fossil evidence to discover ancient organisms and environmental change.

Analyze soil composition, classify rocks and minerals, and model weathering and erosion caused by wind and moving water.

Measure meteorological variables with scientific tools, analyze seasonal patterns, and identify safety procedures during severe weather.

Model Sun-Earth-Moon celestial movements, track daytime shadow shifts, explain lunar phases, and explore planets in our solar system.

Distinguish renewable from non-renewable resources, navigate local habitats with maps, and design waste reduction and conservation actions.

Formulate testable scientific questions, conduct controlled fair tests, analyze evidence-based conclusions, and explore diverse STEM careers.
