What does a student learn in StateNorth Carolina,GradeGrade 6,SubjectScience?

Matter is anything that takes up space and has mass. Students learn to describe the physical properties of solids, liquids, and gases, such as color, texture, density, and melting point, and explain how matter is built from atoms and molecules.

Atoms are the tiny building blocks of everything around us. Students use diagrams or models to show that every material is made of atoms, and that different elements are different because of which type of atom they contain.

Students use diagrams or physical models to show how heating or cooling a substance speeds up or slows down its particles, and how those particle movements cause matter to melt, freeze, or boil.

Students test and compare properties like density, melting point, and solubility that stay the same no matter how much of a substance you have, then contrast those with properties like mass and volume that change depending on how much is present.

Heat moves from warm objects to cool ones, and electricity flows through certain materials but not others. Students learn to explain both patterns and connect them to everyday examples like warming a spoon or lighting a bulb.

Students use diagrams or models to show which way heat moves through convection, radiation, and conduction. Each method moves heat differently, and the models make that direction visible.

Students use diagrams or physical models to show what happens when heat moves into or out of a material. They explain why most solids, liquids, and gases expand when heated and shrink when cooled.

Students test which materials slow down heat transfer and which let it pass through quickly, then compare results. A foam cup versus a plain cup is the kind of test this standard has in mind.

Students sort real materials, like metal spoons or plastic cups, into two groups: things that let heat or electricity pass through and things that block it. They back up their sorting with evidence.

Students build simple circuits and test what happens when the loop is broken. The work shows why electricity only flows when the path from one end of a battery back to the other is complete.

Students learn how energy travels in waves, from the light they see to the sound they hear to the ground shaking during an earthquake. They study what makes waves different from each other, like how high, long, or fast they are.

Students use diagrams to explain how waves repeat in a pattern. They identify the height of a wave (amplitude), how often it repeats (frequency), and its length, then connect a taller wave to more energy.

Students investigate how visible light fits into the broader electromagnetic spectrum and why the human eye can only detect a small slice of it.

Students investigate how fast something vibrates and what it travels through to explain why we hear different sounds. A slower vibration makes a lower pitch; a denser medium carries sound differently.

Students use diagrams or models to show what happens when a wave hits a material: it bounces back, passes through, or gets absorbed. This applies to light, sound, and the waves that travel through the ground during an earthquake.

Plants have roots, stems, and leaves that each do a specific job to keep the plant alive. Students study how those parts work together so the plant can grow, respond to its environment, and make new plants.

Plants run three processes at once to stay alive: photosynthesis turns sunlight into food, respiration releases that food as energy, and transpiration moves water through the plant. Students use models to show how all three connect.

Students compare two types of plants: those with internal tubes that move water and nutrients through stems and roots, and simpler plants like mosses that absorb what they need directly. Students explain how each type gets what it needs to survive.

Students use diagrams or models to show how flowering plants defend themselves, survive in their environment, and spread their seeds.

Students trace how energy moves from the sun through plants, animals, and decomposers in an ecosystem. They also explain how living things like predators and nonliving things like temperature or rainfall shape whether a population grows or shrinks.

Plants capture sunlight and use it to make sugar, which passes to animals that eat those plants and then to decomposers that break down dead matter. Students use diagrams or models to trace that energy flow through an ecosystem.

Students look at data about temperature, rainfall, sunlight, and soil to explain why certain plants and animals thrive in some biomes but struggle or die in others.

Students learn how the Earth, Moon, and Sun move in relation to each other, and why those patterns are predictable. This includes why we have day and night, phases of the Moon, and how stars and other objects in space are organized.

Students use diagrams or physical models to show why Earth has seasons, why tides rise and fall, why the moon changes shape in the sky each night, and what causes eclipses. It all comes down to how the Sun, Earth, and moon move around each other.

Students compare the eight planets by size, gravity, distance from the sun, and surface conditions, then use that data to explain why Earth is the only planet known to support life.

Models show how gravity from the Sun holds planets in their orbits and shapes the layout of the solar system. Students explain why objects stay in place rather than drifting off into space.

Students compare real mission data to get a feel for how enormous space actually is, from the planets in our solar system out to distant galaxies. The numbers are hard to picture, so the focus is on making sense of the scale.

Students learn how the outer layer of Earth gets shaped over time. Volcanic eruptions and shifting plates build up the land; erosion and weathering wear it back down.

Students use diagrams or models to show how Earth is built in layers, from the thin rocky crust underfoot down through the mantle to the dense metal core at the center.

Students explain how slow movements deep in the earth build mountains, shift continents, and trigger earthquakes or volcanic eruptions. The same forces that raise land can also crack and reshape it over millions of years.

Students use diagrams or physical models to trace how rocks slowly break down into soil, showing why sandy soil, clay, and other soil types differ depending on the rock they came from.

Students learn how humans change the land through mining, building, and farming, and how the land shapes where and how humans live.

Students examine real evidence to argue why keeping soil healthy matters for both people and the environment. This includes why scientists monitor the ground beneath us and what happens when soil quality is ignored.

Farming, logging, and other land uses can either protect or wear out the soil and ecosystems humans depend on. Students compare sustainable practices that preserve land long-term with practices that degrade it, and explain why careful stewardship matters.
