What does a student learn in StateLouisiana,GradeGrade 10,SubjectScience?

Students learn that a heavier object needs more force to speed up at the same rate as a lighter one. They work with real data to show how force, mass, and acceleration are mathematically linked.

Students use math to show that when two objects collide or push apart, the total momentum of the system stays the same, as long as no outside force acts on it. Think of billiard balls or a skater pushing off a wall.

Students design and test something that softens a collision, like padding around a phone or a crumple zone in a car. The goal is to reduce the force an object feels on impact.

Students use equations to calculate the pull of gravity between two objects and the push or pull between electrically charged objects. Both forces follow the same basic pattern: they get stronger when the objects have more mass or charge, and weaker as the objects move farther apart.

Running electricity through a wire creates a magnetic field around it. Students design and run experiments to show both sides of this relationship: electricity makes magnetism, and a moving magnet can push electricity through a wire.

Atoms and molecules determine how a material behaves. Students explain why the tiny structure inside metals, plastics, or other designed materials determines whether that material is strong, flexible, or useful for a specific job.

Students build a model or calculation that tracks how energy moves between parts of a system. If you know how much energy every other part gained or lost, you can figure out what happened to the one part you're studying.

Students build diagrams or physical models to show that the total energy in a system comes from two sources: how fast its particles are moving and how those particles are positioned relative to each other.

Students design and build a working device that converts one form of energy into another, like turning motion into electricity or heat into light, then adjust the design until it meets specific requirements.

Students mix two substances at different temperatures and track how heat moves between them until both reach the same temperature. The experiment shows that heat always flows from warmer to cooler, never the other way.

Students draw or build a model showing how two magnets or charged objects push and pull each other without touching. The model shows how the force between them changes as they move closer or farther apart, and where the energy goes.

Students read published sources on nuclear power and judge whether the claims hold up, comparing the evidence to what those sources say about fossil fuels, wind, and solar energy.

Students use math equations to show how a wave's frequency, wavelength, and speed are connected, and how those relationships change depending on what the wave is moving through, like air, water, or glass.

Students read scientific articles and judge whether the evidence actually supports claims about how radio waves, visible light, X-rays, or other forms of electromagnetic radiation affect the body or other materials.

Students use the periodic table to predict how an element will behave, based on where it sits in the table. Position reveals patterns in electron arrangement and atomic structure that explain properties like reactivity and conductivity.

Students learn to predict what a chemical reaction will produce by looking at where atoms sit on the periodic table. The location of an element on the table hints at how readily it gives up or grabs electrons, which drives what new substances form.

Students design and run an experiment comparing how substances look and behave (think melting point or hardness) to figure out how strongly their atoms or molecules are pulling on each other.

Chemical reactions break old bonds and form new ones. If the new bonds store less energy than the old ones did, the leftover energy is released as heat or light. If the new bonds store more, the reaction pulls energy in from the surroundings.

Students learn why reactions speed up or slow down. Heating a mixture or adding more of a substance makes particles collide more often, changing how fast a chemical reaction runs.

Students adjust conditions like temperature or pressure to push a chemical reaction toward making more of the desired product. The focus is on understanding why those adjustments work, not just guessing.

In a chemical reaction, no atoms appear or disappear. Students use math to show that the total mass of the starting materials equals the total mass of the products.

Students draw or diagram what happens inside an atom's nucleus during nuclear reactions like splitting atoms apart or fusing them together. The models show how the nucleus changes and why those reactions release so much energy.

Light behaves like a wave in some experiments and like a stream of particles in others. Students look at real evidence to decide which model better explains a given situation, such as how a radio signal travels or how light knocks electrons off metal.

Students ask and refine questions about how DNA and chromosomes carry the instructions that pass traits from parents to children. The focus is on forming good scientific questions, not just answering them.

Students explain why children inherit similar but not identical traits from their parents. They use evidence to argue that genetic variation comes from how chromosomes shuffle during reproduction or from copying errors and environmental damage in DNA.

Students use probability and data to explain why traits like eye color or height vary across a population. They look at patterns in real groups to understand why some traits are common and others are rare.

Students use graphs, equations, or models to explain what limits how many animals a habitat can support and why species diversity shifts when food, water, or space runs short.

Students use graphs, equations, or data tables to show how energy moves through a food web and how matter like carbon or nitrogen cycles through living things and the environment.

When conditions in an ecosystem stay steady, populations tend to hold at consistent levels. Students look at real evidence to judge whether that claim holds up, and what happens to species counts when conditions shift enough to push the ecosystem into a new state.

Students design and test a plan to reduce real environmental damage, such as habitat loss or pollution, then revise it based on evidence. The focus is on building a workable solution, not just describing the problem.

Students examine fossil records, DNA comparisons, and anatomical similarities across species to build a case that all living things share common ancestors. The evidence comes from multiple independent fields, each pointing to the same conclusion.

Students build a written explanation, using evidence, for why species change over time: populations can grow fast, offspring inherit varied traits through mutation and reproduction, resources run short, and the individuals best suited to their environment survive to have more offspring.

Students use probability and data to explain why a helpful genetic trait spreads through a population over generations. If a trait helps organisms survive and reproduce, its frequency rises while the less-helpful version declines.

Students explain, using real examples, how natural selection and other forces (like random chance or migration) gradually shift which genes are common in a population over generations.

When the environment shifts, some traits help animals survive and others don't. Students study real examples to explain why a species can spread, split into something new, or disappear entirely.

DNA holds the instructions for building proteins, and proteins do the actual work inside every cell. Students learn how a molecule's shape determines its job, and why changes to that shape can disrupt how the body functions.

The body is organized in layers: cells group into tissues, tissues into organs, and organs into systems that keep everything running. Students build or interpret a model showing how each layer depends on the one below it.

Students design and run an experiment to show how the body keeps conditions stable, like how heart rate rises during exercise and then returns to normal once activity stops.

Students use diagrams or models to show how cells divide and specialize into different types, like muscle or nerve cells, to build and maintain a complex body.

Students trace how plants capture sunlight and convert it into sugar stored in their cells. They use a diagram or model to show where that energy comes from and where it ends up.

Students trace how the carbon, hydrogen, and oxygen locked in sugar get rearranged, sometimes with nitrogen or sulfur added, to build the proteins and other large molecules a living cell needs.

Cellular respiration is how cells break down food and oxygen to release usable energy. Students use diagrams or models to show how chemical bonds in glucose and oxygen break apart and re-form into carbon dioxide, water, and energy the body can use.

Viruses and bacteria reproduce and mutate fast, which makes them hard to treat. Students study how the immune system responds to infection and why those biological details shape the way doctors and researchers design vaccines and medicines.

Students map out how slow processes deep inside Earth, like magma moving through the mantle, and faster surface forces, like erosion, work together over millions of years to build mountain ranges, ocean trenches, and ocean floor.

Reading real data about glaciers, forests, or ocean temperatures, students explain how one change on Earth's surface sets off a chain reaction that alters other systems. Melting ice, for example, exposes darker ground that absorbs more heat and drives further warming.

Students build a model showing how heat deep inside Earth moves rock and other material slowly upward, sideways, and back down again, the same way warm soup rises in a pot.

Students examine temperature records, ocean data, and atmospheric measurements to explain why shifts in how much energy Earth absorbs or releases change long-term weather patterns and climate conditions.

Students plan and run experiments on water: how it dissolves, erodes, and shapes the land around it. The goal is understanding why water behaves the way it does and what it does to rock, soil, and other earth materials over time.

Students build a model using numbers and data to show how carbon moves through the ocean, air, rocks, and living things. The goal is to see how a change in one part of the system affects the others.

Students build an argument, using fossil records and geological evidence, for how living things and Earth's oceans, atmosphere, and landmasses have shaped each other over billions of years.

Students map the sun's life from birth to eventual death and explain how nuclear fusion in its core produces the energy that travels to Earth as light and heat.

Stars are giant element factories. Students explain how stars fuse lighter atoms into heavier ones as they age, and how the most massive stars scatter those elements across space when they explode.

Students use math to predict where planets, moons, and other objects in the solar system will be as they orbit the sun. Think of it as calculating the path a ball traces when you swing it on a string, but at a planetary scale.

Continents and ocean floors are constantly shifting, and the rocks they carry hold clues to when and where they formed. Students use those clues to explain why rocks in different parts of the world are different ages.

Students use starlight patterns, the movement of distant galaxies, and what the universe is made of to build a scientific explanation for how the universe began.

Students use evidence from rocks, meteorites, and other planetary surfaces to piece together how Earth formed and what its earliest history looked like. Scientific reasoning connects the clues.

Students explain, using real evidence, how access to water, land, and minerals shapes where and how people live, and how natural disasters and climate shifts have pushed societies to adapt, migrate, or change how they use resources.

Students compare real proposals for mining or energy production by weighing what each option costs against what it delivers. The goal is to identify which solution does the most good with the least harm and expense.

Students build a working computer simulation that shows how decisions about natural resources (like water, farmland, or forests) ripple through human population growth and wildlife diversity. Change one variable and watch the rest shift.

Students look at a real design (a water filter, a green roof, a runoff barrier) and judge whether it actually reduces harm to nature, then suggest concrete improvements based on evidence.

Students study real temperature records, sea-level measurements, and computer climate models to predict how rising temperatures will affect things like coastlines, weather patterns, and freshwater supplies over the coming decades.

Students use computer models or simulations to show how the atmosphere, oceans, land, and living things connect, and how human activity is changing those connections.

Students look at real data on Louisiana's land, water, and wildlife to figure out what makes resource use sustainable over time and what puts those resources at risk.

Students pick one Louisiana natural resource, such as wetlands, fisheries, or timber, and research how the state has managed or protected it over the past 50 years. They weigh tradeoffs across cost, politics, and community impact, then explain what has worked and what hasn't.

Students look at real data on environmental decisions, like pollution limits or land-use policies, and weigh what was gained against what was lost. The goal is to judge whether a choice was worth its costs.

Students identify where pollution enters rivers and lakes from diffuse sources like farms, roads, and parking lots, then design and assess a solution to reduce that runoff before it reaches the water.

Students use a diagram or simulation to predict how a pollutant, like contaminated water or smog, shrinks or shifts the size of an animal or plant population in a given area.

Students gather evidence from multiple sources to argue why invasive species harm Louisiana's native plants and animals. They explain the real ecological damage those outside species cause and back every claim with data.

Students build arguments for and against single-use products compared to reusable ones, weighing environmental costs and benefits on both sides.
