Students describe Earth's four major systems and explain interactions such as rain, erosion, and gas exchange.

Students define design problems, compare solutions using criteria and constraints, test prototypes, and optimize through iteration.

Students model matter cycling and energy flow using food chains, food webs, and roles of producers, consumers, and decomposers.

Students use a particle model to explain states of matter, relate temperature to particle motion, and apply conservation of matter.

Students identify mixtures and solutions and choose separation methods such as filtering, evaporation, and magnetism.

Students distinguish physical and chemical changes and cite evidence such as gas, color, odor, and temperature change.

Students identify variables, plan controlled investigations, analyze data in tables and graphs, and communicate findings.

Students use models to explain day/night, seasons, and orbits; overview planets and the sun as a star.

Students graph Earth's water distribution, compare freshwater reservoirs, and discuss availability and conservation.

Students explain that food provides energy for activity and materials for growth, connecting organisms' needs to nutrients and simple food pathways.

Students explain gravity as a downward pull toward Earth and support arguments with everyday observational evidence about falling objects and motion.

Students evaluate how human activities affect Earth systems and judge community solutions that protect resources using evidence.

Students explain differences in how bright stars appear using distance and intrinsic brightness ideas, and recognize the Sun as a star.

Students deepen understanding of how animals use senses and signals to gather information, respond, and survive.

Students explore how technology extends senses and measurement and enables scientific discoveries.
