Thinking and working like scientists
Students learn how real science gets done. They ask testable questions, plan experiments, collect data, and back up their claims with evidence instead of opinion.
High school is when science stops being a tour of topics and becomes a way of thinking. Students dig into the why behind what they see, from atoms and energy to cells, genes, and the systems that shape Earth and its climate. They run real investigations, work with data, and back up their claims with evidence instead of guesses. By spring, students can read a science article in the news and explain whether the conclusion actually holds up.
Students learn how real science gets done. They ask testable questions, plan experiments, collect data, and back up their claims with evidence instead of opinion.
Students dig into what everything is made of and what makes it move. They study atoms, chemical reactions, motion, and how energy shifts from one form to another.
Students explore how sound, light, and other waves carry energy and signals. They see how the same ideas show up in music, phones, medical scans, and wireless tech.
Students study how living things work, from a single cell to a whole forest. They follow how food, water, and energy move through plants, animals, and the environments they share.
Students learn how traits pass from parents to children and why living things look so different from one another. They see how species change over long stretches of time.
Students zoom out to the planet and the solar system. They look at how Earth's land, oceans, and air work together, and how human choices change the climate and shape engineering solutions.
Students learn to turn a curiosity or real-world problem into a question that can actually be tested or a challenge that can be built and solved. The focus is on framing the right question before any experiment or design work begins.
Students build or use diagrams, simulations, and physical replicas to explain how something works or to test an engineering design before building the real thing.
Students design and run their own experiments to collect real data and find out whether their hypothesis holds up.
Students look at data from an experiment or investigation and find patterns that point to a conclusion. This is the skill behind reading a graph, comparing results, and deciding what the numbers actually mean.
Students apply math and data analysis to back up scientific arguments. That might mean calculating a result, interpreting a graph, or using a model to show why a conclusion holds up.
Students build written explanations for scientific phenomena by connecting real evidence to established principles. The explanation has to hold up against the data, not just sound reasonable.
Students look at two or more explanations for the same science question, then use data and evidence to argue which one holds up better. The goal is to reason through disagreement, not just pick a side.
Students read scientific texts and data, judge how reliable the sources are, and explain their findings clearly to others. This practice runs through lab reports, research projects, and class discussions.

Students study how atoms and molecules are built and how they interact with each other. That understanding explains physical phenomena like why ice melts, why metals conduct heat, or why some materials dissolve in water.
Students learn Newton's laws of motion and use them to explain why objects speed up, slow down, or stay still. They also explore how forces and energy are conserved in collisions and other real-world situations.
Students trace how energy changes form and moves from one object to another, while the total amount stays the same. A rolling ball, a warming pan, or a charging phone all follow the same rule: energy shifts, but none disappears.
Students study how waves, like sound, light, and radio signals, move energy and information from place to place. They look at real applications, such as how a cell phone signal or medical imaging technology actually works.

Students study how living things are built and how they work, starting at the cell level and zooming out to whole-body systems like digestion or circulation.
Students trace how energy moves through a food web and how matter like carbon and water gets recycled through living things. They also study how species in a community depend on, compete with, or affect each other.
Students trace how traits like eye color or blood type pass from parents to offspring, and explore why siblings can look different even when they share the same parents.
Students examine how all living things share basic biological traits while also showing enormous variety, then explore the processes (like natural selection and genetic change) that drive those differences over generations.

Students examine where Earth sits in the solar system, how planets and moons move in predictable patterns, and how Earth itself formed and changed over billions of years.
Students study how Earth's major systems (land, water, air, and living things) connect and affect one another. A volcanic eruption, a flood, or a shift in climate shows how a change in one system ripples through the rest.
Students examine how things like farming, building, and burning fuel change the land, water, and air around us. They also look at how earthquakes, floods, and other natural events shape where and how people live.

Students identify a real problem, sketch or build possible solutions, then test and improve their design until it works better. The focus is on the back-and-forth cycle of trying, failing, and fixing.
Engineering and society push and pull on each other. Students explore how new technologies shape daily life and how social needs, values, and problems drive engineers to build new solutions.

Federally administered sample-based assessment in reading, mathematics, science, and writing. NAEP results inform state-by-state comparisons rather than individual student or school accountability.
Students study big ideas across physics, chemistry, biology, and earth science. They learn how atoms make up matter, how forces move objects, how cells and ecosystems work, and how Earth fits in the universe. They also practice running real investigations and explaining what the evidence shows.
Ask students to explain something they saw in class using their own words and a quick sketch. Watch a short science video together and ask what evidence the scientist used. Cooking, gardening, and fixing things around the house all count as science talk.
Memorizing helps, but most of the work is reasoning from evidence. Students are expected to ask questions, run investigations, look at data, and argue for the best explanation. If a student is only memorizing vocabulary, they are missing half the course.
Most teachers anchor each unit in a phenomenon and pull in the practices students need to explain it. Physical science ideas like energy and forces often come first because they show up again in biology and earth science. Save evolution and Earth systems for later units that can pull everything together.
Analyzing data and arguing from evidence tend to lag behind the others. Students can often run a lab but struggle to say what the numbers actually mean or defend a claim when a classmate disagrees. Short, repeated practice with real data sets helps more than one big project.
A student who is ready for the next course can look at an unfamiliar phenomenon, ask a testable question, and explain it using evidence and a scientific principle. They can read a graph or article, spot weak reasoning, and write a short argument that holds up.
A fair amount. Students use algebra to work with rates, forces, and energy, and they use graphs and basic statistics to make sense of data. Students who are shaky on algebra often need extra support during physics and chemistry units.
Engineering design gives students a reason to use the science they just learned. A good design task asks students to solve a real problem, test a prototype, and improve it based on data. One or two solid design projects per year tend to land better than many short ones.
