Thinking and working like scientists
Students start the year learning how scientists and engineers actually work. They ask questions, plan small investigations, and record what they notice using sketches, charts, and simple measurements.
This is the year science starts feeling like detective work. Students stop just naming parts of the world and start asking why things happen, then testing their ideas. They track where matter and energy go, from a plant in the soil to planets circling the sun. By spring, students can run a simple experiment, read the results, and explain what the evidence shows.
Students start the year learning how scientists and engineers actually work. They ask questions, plan small investigations, and record what they notice using sketches, charts, and simple measurements.
Students look closely at what things are made of and how they move. They test how forces change motion, watch energy move from one place to another, and explore how light and sound carry signals.
Students study how plants and animals grow, get food, and pass traits to their young. They map how living things in a pond, forest, or backyard depend on each other and on sunlight, air, and water.
Students zoom out to Earth and the sky. They look at patterns of day, night, and seasons, study how land, water, and air interact, and talk about how people can protect resources and prepare for storms.
Students close the year as engineers. They pick a real problem, sketch possible fixes, build a simple version, and test it. Then they use what went wrong to make the next try better.
Students practice turning curiosity into a testable question or a real problem an engineer could actually solve. This is the starting point for every science investigation and design challenge in fifth grade.
Students build or draw models, like diagrams or physical mock-ups, to show how something in nature works or how a design could solve a problem.
Students plan and run their own experiments to gather real data and test whether their ideas hold up.
Students look at collected data, like measurements or observations, to spot patterns and figure out what the results actually mean.
Students use numbers, measurements, and simple calculations to back up a scientific idea. Instead of just describing what they observed, they show it with data.
Students build written explanations for science observations using evidence from experiments or data. The explanation has to connect back to a real scientific idea, not just a guess.
Students look at two or more explanations or solutions, then use data and observations to argue which one holds up better. The focus is on the evidence, not just the opinion.
Students read science sources, decide which information is trustworthy, and explain what they learned in writing or discussion. The focus is on finding good information and sharing it clearly.

Students investigate what matter is made of at the smallest scale, atoms and molecules, and use that knowledge to explain everyday physical events like melting, dissolving, or mixing.
Students study why objects speed up, slow down, or stay still by exploring how pushes and pulls work together. They learn Newton's basic rules of motion and see how energy stays constant even when it changes form.
Students explore how energy shows up as light, heat, sound, or motion, then trace how it moves from one object to another. They learn that energy doesn't disappear when it seems to vanish; it just changes form.
Students study how waves, like sound and light, move energy from place to place. They explore how those same waves carry information, such as the signals behind a radio broadcast or a phone call.

Students examine how living things are built, from the tiny cells that make up every part of a body to the larger systems those parts form together.
Students trace how energy from the sun and matter like water and nutrients move through an ecosystem, and study how plants, animals, and other living things depend on and affect each other.
Students compare traits in parents and offspring to see which features get passed down and which ones vary. Think eye color, plant height, or fur pattern across a family of animals.
Students look at how all living things share basic traits while still being wildly different from one another, then explore why those differences build up over generations.

Students explore where Earth sits in the solar system, how the planets move in predictable patterns, and how Earth itself has changed over billions of years.
Students study how Earth's land, water, air, and living things connect and affect each other. They look at real examples of those connections, like how rain shapes soil or how plants change the air.
Students look at how things like farming, building, and burning fuel change the land, water, and air around us. They also study how earthquakes, floods, and wildfires disrupt where and how people live.

Computer-based science assessment in grade 5, aligned to the NGSS-based Delaware Science Standards.
Students study four big areas: matter and energy, living things and ecosystems, Earth and space, and engineering design. They also practice the habits scientists use, like asking questions, running tests, and explaining results with evidence.
Ask students to explain what they noticed and why they think it happened. Cooking, gardening, weather watching, and fixing things around the house all count. Five minutes of curious questions does more than a worksheet.
Students should be able to run a simple investigation, record what they find, and explain a result using evidence. They should also be comfortable building a model or design, testing it, and improving it.
Most teachers anchor each quarter in one strand and weave the practices through all of them. Starting with physical science gives students a vocabulary for matter and energy that supports later work in ecosystems and Earth systems.
Not at this level. Fifth graders are expected to investigate, argue from evidence, and design solutions. Facts matter, but explaining how students know something matters more.
Energy transfer, the difference between weight and mass, and ecosystem cycles are common sticking points. Plan extra hands-on time and short writing prompts where students explain cause and effect in their own words.
A large share. Students learn the practices by running real investigations, not by reading about them. Aim for at least one investigation or design challenge each unit, with time to record data and revise thinking.
Listen for how they explain things. A ready fifth grader can describe what they tested, what happened, and what the evidence shows, even if the words are simple. They should also be willing to change their mind when the data says so.
