What does a student learn in
California, Grade 6, Science, any focus ?

Students build or draw a model of the Earth, sun, and moon to explain why the moon appears to change shape each month, why eclipses happen, and why seasons shift throughout the year.

Gravity pulls every planet, moon, and star toward other objects with mass. Students build or use a model to show how that pull keeps planets orbiting the sun and holds stars together in a galaxy.

Students study size and distance across the solar system, comparing planets, moons, and the sun using real data. The goal is to understand how enormous the gaps between objects actually are.

Rock layers act like a timeline buried underground. Students use evidence from those layers to explain how scientists divide Earth's 4.6-billion-year history into eras and periods.

Students map how rocks, water, and soil move through Earth over time, then trace the heat and pressure that keep those cycles going.

Rocks, landforms, and coastlines have been shaped by earthquakes, erosion, and volcanic activity over millions of years. Students explain how those forces work at different speeds and scales, from a single landslide to continents shifting across deep time.

Students study fossil locations, rock patterns, and the shapes of continents to figure out how Earth's plates have shifted over millions of years.

Students map how water moves between oceans, clouds, and land as sunlight heats it up and gravity pulls it back down. The goal is to show the full cycle, not just name its parts.

Students track how moving air masses collide and push against each other, then use that data to explain why temperature, wind, and precipitation change from one day to the next.

Students map how sunlight hits Earth unevenly and how Earth's spin sets air and ocean currents in motion. Together, those forces shape the typical weather patterns a region gets year after year.

Minerals, oil, and fresh water aren't spread evenly around the planet. Students explain why using evidence tied to real geoscience processes, like volcanic activity or the movement of ancient seas, that shaped where those resources ended up.

Students study earthquake, volcano, and flood records to spot patterns that help predict where disasters are likely to strike next. That data shapes the design of early-warning systems and stronger buildings.

Students pick a real environmental problem, like water pollution or habitat loss, and design a plan to track and reduce the damage. The focus is on using science to guide the solution, not just describing the issue.

Students examine how a growing population and rising resource use (water, land, energy) put pressure on Earth's systems. They back up their argument with real evidence, not just an opinion.

Students look at temperature records, ice core data, and other evidence to figure out what has driven global warming over the last hundred years. The focus is on forming good questions, not just accepting answers.

Students build or interpret a diagram showing how the Earth, sun, and moon move around each other to explain why the moon appears to change shape each month, why eclipses happen, and why seasons change.

Gravity pulls every planet, moon, and star toward other massive objects. Students model how that pull keeps planets orbiting the sun and holds the spinning arms of a galaxy together.

Students compare the sizes and distances of planets, moons, and the sun using real data. The numbers are so large that students practice converting them into scaled-down models to make sense of the spacing.

Rock layers act like pages in Earth's history book. Students use evidence from those layers to explain how scientists divide 4.6 billion years of Earth's past into named chunks of time.

Students map how rock, water, and other materials move through Earth over time, and trace the energy source (mostly heat from inside the planet and sunlight) that keeps the cycle going.

Rocks, landforms, and coastlines are always changing, just at different speeds. Students study how earthquakes reshape land in seconds while erosion carves canyons over millions of years, then use real evidence to explain why Earth's surface looks the way it does today.

Fossils, rock layers, and the jagged edges of continents all tell the same story. Students read that evidence to figure out how Earth's plates have shifted and drifted over millions of years.

Students trace how water moves from oceans to clouds to rain and back again. They build a diagram or model showing how sunlight and gravity keep that cycle running.

Students track how air masses move and collide to explain why weather changes. They gather real data, like temperature and pressure readings, to connect what's happening in the atmosphere to the forecast outside.

Students build a model showing why some parts of Earth get more sun than others, and how that uneven warmth, combined with Earth's spin, drives wind and ocean current patterns that shape the climate where you live.

Students explain why oil, gold, or clean water is plentiful in some places and scarce in others. The reason always comes back to geologic processes, like volcanic activity or erosion, that concentrated those resources over millions of years.

Students study real data from earthquakes, volcanoes, and floods to spot patterns that help predict where disasters are likely to strike next. That same evidence shapes the tools and warning systems communities build to reduce harm.

Students pick a real environmental problem, such as water pollution or habitat loss, and design a step-by-step plan to track and reduce that impact using science concepts they already know.

Students build a case, using real data, for how a growing human population and rising resource use put pressure on land, water, and air. The argument has to be backed by evidence, not opinion.

Students examine real data on global temperature changes and ask focused questions about what caused them. The goal is to understand which natural and human factors drove the warming trend seen over the last 100 years.

Students identify exactly what a solution must do and what limits it, including cost, materials, safety, and effects on people or the environment. Getting those boundaries clear before building is what keeps a design from failing.

Students compare two or more design solutions side by side, checking each one against the problem's requirements and limits to decide which works best.

Students compare test results from multiple design solutions, then mix and match the strongest features of each to build a better version that solves the original problem more effectively.

Students spell out exactly what a solution must do and what it cannot do before any building starts. That means listing real-world limits like cost, materials, and safety alongside any science that rules certain designs out.

Students compare two or more design solutions side by side, using a clear set of criteria to judge which one best solves the problem within the given limits, such as cost, materials, or size.

Students compare test results from multiple design attempts to find what worked best in each one, then combine those strengths into a single improved design.

Students investigate whether living things are made of cells by examining samples under a microscope. They compare single-celled organisms to plants and animals built from many different cell types.

Students explain how the body works as a system of smaller parts, like how muscle cells group into muscles that help bones move. They back up their explanation with evidence.

Students study why certain animal behaviors and plant structures make reproduction more likely to succeed. They use real evidence to explain how a flower's shape or an animal's mating call gives that species a better shot at producing offspring.

Students explain why two plants or animals of the same species can grow to different sizes. They use evidence to show how genes and surroundings, like sunlight or food supply, both shape how an organism develops.

Students explain how plants use sunlight, water, and carbon dioxide to make food, and how that process moves energy and raw materials through living things. The evidence comes from real data, not just a textbook summary.

Students learn how the body breaks down food and rebuilds it into new materials, some used for growth and some burned for energy. It is chemistry happening inside every cell.

Students learn how the body's sense organs pick up signals from the world and send them to the brain, which either acts on them right away or stores them as memories.

Students look at real data (food, water, space) to explain why animal and plant populations grow, shrink, or move in a given ecosystem.

Students study how living things depend on and affect each other, then predict whether those same patterns would show up in a different ecosystem. Think prey and predator cycles, or how a plant's spread changes what animals can live nearby.

Students map how matter (like water or carbon) moves through an ecosystem and how energy flows from the sun through plants, animals, and the soil. The model shows how living things and their environment depend on each other.

When something in an ecosystem changes, like a drought drying up a pond or a new predator moving in, the animals and plants living there are affected. Students use real data to argue why those population changes happen.

Students look at different real-world plans for protecting wildlife and healthy ecosystems, then decide which plan works best and why.

Genes carry the instructions cells use to build proteins. When a gene's instructions change (a mutation), the proteins it builds may change too, sometimes harming the organism, sometimes helping it, and sometimes making no difference at all.

Students explain why a child does not look exactly like either parent. They use a diagram or model to show how sexual reproduction mixes genetic information, while asexual reproduction copies it exactly.

Students study fossil evidence to figure out how life on Earth has changed over millions of years, including which creatures once existed and which died out. They look for patterns across the fossil record the same way a detective looks for clues.

Students compare body parts across living animals and fossils to explain how species are related and how they changed over time.

Students look at drawings of embryos from different animals (fish, frogs, birds, humans) and find the striking similarities in early development. Those shared patterns reveal how closely related species are, even when the grown adults look nothing alike.

Some animals or plants in a group are born slightly different from the rest. Those differences can make certain individuals more likely to survive and have offspring in a given place.

Students research how tools like selective breeding and genetic modification let humans shape which traits plants or animals pass on to the next generation.

Students use graphs and data to explain why some traits become more or less common in a population over generations. They show how survival pressures push populations to change over time.

Students investigate whether living things are made of one cell or many by examining real specimens or slides. The goal is to find direct evidence, not just read about it.

Students study why certain animal behaviors and plant structures make reproduction more likely to succeed. They back their explanations with real evidence, showing how a bird's mating call or a flower's shape helps the species keep going.

Students explain why two plants or animals of the same species can grow up very differently, using evidence that points to causes like diet, sunlight, or traits passed down from parents.

Students explain how plants use sunlight, water, and carbon dioxide to make food, and how that process moves energy and materials through living things. This is the foundation for understanding why plants matter to nearly every food chain.

Students trace how food breaks down inside the body and gets rebuilt into new molecules that fuel growth and movement. The atoms in food don't disappear; they rearrange through chemical reactions to keep the body running.

Sensory receptors pick up signals from the world around us and send messages to the brain. The brain either acts on those messages right away or stores them as memories.

Students look at real data, like population counts or food supply records, and explain how a shortage or surplus of food, water, or shelter affects how many organisms survive in an ecosystem.

Students study how living things affect each other, like predators and prey or plants and pollinators, then explain why those same patterns show up across different ecosystems.

Students draw or diagram how matter (like water, carbon, or nutrients) moves through an ecosystem and how energy flows from the sun through plants, animals, and decomposers. The model shows how living things depend on nonliving parts like soil, air, and water.

When part of an ecosystem changes, such as a drought drying up a river or a new predator moving in, other species in that area grow, shrink, or disappear. Students use real data to build an argument explaining why.

Students compare different real-world plans for protecting wildlife and healthy ecosystems, then judge which approach works best and why. The focus is on trade-offs, not just picking a favorite.

A mutation is a change in a gene's instructions. Students learn how that small change can alter the proteins a cell builds, and why the result might harm the organism, help it, or make no difference at all.

Students model how living things pass on genetic information, showing why offspring from asexual reproduction are genetic copies of one parent while offspring from sexual reproduction inherit a mix from two parents.

Fossils reveal which creatures lived long ago, which died out, and how life has changed over millions of years. Students study fossil data to find patterns that explain why some species survived and others disappeared.

Students compare body structures across living animals and fossils to explain how species are related and how they changed over time.

Students look at drawings of animal embryos at different growth stages and find similarities that don't show up once the animals are fully grown. Those hidden patterns help scientists figure out which species are more closely related than they appear as adults.

Students explain, using real examples, why some individuals in a species survive and reproduce more than others. The key is genetic variation: small inherited differences can make certain individuals better suited to their environment.

Students look at measurements and observations from a science experiment to figure out whether a chemical reaction happened. If the properties of the materials changed in ways that can't be undone, like a new color, gas, or solid forming, a reaction likely occurred.

Students trace everyday synthetic materials, like plastic or nylon, back to the natural resources they came from. They also look at how those materials change daily life, for better or worse.

Students build a diagram or model showing what happens to water, wax, or another pure substance as it heats up or cools down: particles speed up or slow down, temperature rises or falls, and the substance shifts between solid, liquid, and gas.

In a chemical reaction, atoms rearrange but none appear or disappear. Students build and use models to show why the total mass before and after a reaction stays the same.

Students design and test a device that uses a chemical reaction to either heat up or cool down, like a hand warmer or a cold pack. They adjust the design based on what the test results show.

Students figure out how two objects push back on each other when they collide, then use that idea to design a solution to a real problem. Think of a bumper or a crash pad built to control what happens at the moment of impact.

Students plan and run an experiment to show that a heavier object needs more force to speed up or slow down, and that multiple forces acting on the same object add together to change how it moves.

Students look at data to figure out what makes electric and magnetic forces stronger or weaker, such as how distance or the number of coils changes the pull of a magnet.

Students build an argument, using real evidence, that gravity pulls objects toward each other and that heavier objects pull with more force. They learn why a bowling ball and a marble don't fall the same way on a scale.

Students test how magnets or charged objects push and pull each other without touching. They also judge whether the experiment was set up fairly enough to trust the results.

Students read and build graphs that show how a moving object's energy changes based on how heavy it is and how fast it's going. A heavier or faster object carries more kinetic energy.

Students draw or diagram how the distance between two objects (like a stretched rubber band or a ball held high) changes how much stored energy the system holds. Closer or farther apart means more or less potential energy ready to release.

Students design and build a device to control heat transfer, then test whether it actually works. Think of it as engineering a cooler that keeps ice frozen or a container that holds heat in.

Students plan an experiment to find out how the amount of heat added, the type of material, and how much of it there is all affect how much the temperature rises.

When a moving object speeds up or slows down, energy has moved into or out of it. Students learn to build and explain an argument for why that energy had to come from somewhere or go somewhere.

Students learn that bigger waves carry more energy. They use graphs and equations to show how a wave's height (amplitude) relates to the energy it moves from place to place.

Students learn that when a wave (like light or sound) hits a material, it either bounces back, passes through, or gets soaked up. They use diagrams or physical models to show which happens with different materials.

Students compare digital and analog signals, then use scientific evidence to explain why digital signals carry information more reliably, even when there is interference or noise in the transmission.

Students draw or build models showing how atoms link together to form molecules like water or table salt. The goal is to see how the type and arrangement of atoms determine what a substance is.

Students look at the properties of materials before and after mixing or heating them to decide if a new substance was formed. A color change, gas bubbles, or a new smell are the kinds of clues that signal a chemical reaction happened.

Students trace everyday synthetic materials, like plastic or nylon, back to the natural resources they came from, then think through the trade-offs those materials create for people and the environment.

Students build a diagram or model showing what happens to the particles inside a substance as it heats up or cools down, predicting when it will melt, freeze, or boil.

Students build a model showing that atoms rearrange during a chemical reaction but none appear or disappear. Because the atom count stays the same, the total mass before and after the reaction is equal.

Students design and build a device that uses a chemical reaction to produce heat or cold, then test it and improve it based on what they find. Think hand warmers or instant ice packs.

Students learn that every push or pull has an equal push or pull in the opposite direction, then use that rule to solve a real problem, like designing a bumper or padding that controls what happens when two moving objects collide.

Students plan and run an experiment to show that how much an object speeds up or slows down depends on how hard it's pushed or pulled and how heavy it is. A heavier object needs more force to change direction than a lighter one.

Students look at data to figure out what makes electric and magnetic forces stronger or weaker. They ask questions about patterns in the data to find the key factors at work.

Students build an argument, using data and examples, for why gravity pulls objects together and why heavier objects pull on each other more strongly than lighter ones do.

Students test how magnets or electrically charged objects push and pull each other without touching. The investigation shows that invisible force fields exist in the space between objects.

Students read and build graphs that show how a moving object's energy changes when it gets heavier or faster. A heavier car rolling downhill carries more energy than a lighter one, and a faster ball hits harder than a slower one.

When objects that push or pull on each other from a distance move closer together or farther apart, the amount of stored energy in the system changes. Students build a model to show how that stored energy grows or shrinks as the arrangement shifts.

Students design and build a device to control heat transfer, then test whether it actually works. Think of an insulated lunch bag that keeps food warm or a solar cooker that traps heat on purpose.

Students design an experiment to figure out how heating different materials changes their temperature. They test how the type of material and its mass affect how much heat it takes to warm something up.

When a moving object speeds up or slows down, energy has moved into or out of it. Students build an argument explaining where that energy came from or went, using real examples like a rolling ball or a braking bike.

Students use math to describe how waves work, focusing on one key relationship: a wave with a bigger amplitude carries more energy. Think of it like sound getting louder as the wave grows taller.

Waves (like light or sound) behave differently depending on what material they hit. Students model how a wave can bounce off a surface, pass through it, or get soaked up by it, and explain what determines which happens.

Students compare digital and analog signals, then use science and technical sources to explain why digital signals are less likely to scramble or lose information during transmission.
