Thinking and working like scientists
Students learn to ask questions they can actually test, plan a fair experiment, and record what they see. They start drawing simple models to explain how something works.
This is the year science starts feeling like real investigating. Students ask questions, run simple tests, and use what they find to explain how things work. They look closely at forces and motion, how living things survive in their habitats, and patterns in weather and the sky. By spring, students can plan a fair test, record what happens, and explain their answer using the evidence they gathered.
Students learn to ask questions they can actually test, plan a fair experiment, and record what they see. They start drawing simple models to explain how something works.
Students push, pull, and roll objects to see what makes things speed up, slow down, or stop. They explore how energy moves through sound, light, heat, and motion.
Students look at how plants and animals are built to survive where they live, what they need to grow, and how traits pass from parents to offspring. They notice patterns across a pond, a forest, or a backyard.
Students track the sun, moon, and weather patterns and dig into rocks, water, and soil. They see how the parts of Earth fit together and how people change the land around them.
Students take on a small engineering challenge, sketch a few ideas, build something, and test it. They use what went wrong on the first try to make the next version better.
Students come up with questions about the world around them that a real test or experiment could answer. They also describe problems clearly enough that an engineer or scientist could start working on a solution.
Students draw or build a simple model, like a diagram of the water cycle or a sketch of a bridge design, to show how something works or explain why something happens.
Students plan a test or experiment, carry it out, and record what they find. The point is to gather real information that helps answer a question or check whether an idea holds up.
Students look at data from an experiment, spot patterns in the numbers or results, and explain what those patterns mean.
Students use counting, measuring, and simple math to back up what they observe in science. Instead of just saying something is "bigger" or "faster," they put a number to it.
Students take what they observed or measured and write an explanation that uses that evidence to show why something happened or how something works.
Students look at two possible explanations or solutions, then use evidence from their investigations to argue which one holds up better.
Students read simple science texts, decide whether the information makes sense, and share what they learned in words or pictures.

Students explore what everyday materials are made of and why they behave the way they do. They investigate how tiny particles interact to explain physical changes they can observe and measure.
Students test how pushes and pulls change the way objects move, and explore why some things stay still while others speed up, slow down, or change direction.
Students explore how energy shows up in different forms, like heat, light, and sound, and track where it goes when it moves from one object to another. They learn that energy is never lost, just changed or passed along.
Students explore how waves (like sound and light) carry energy and send information from one place to another. They investigate real examples, such as how a phone call travels or how a drum sends vibrations through the air.

Students look at how living things are built and how they work, from the tiny cells inside a leaf or a finger to the larger body systems those cells form together.
Students trace how food energy moves from plants to animals and back into the soil, and look at how living things in one place depend on and affect each other.
Students look at how traits like eye color or height get passed from parents to offspring, and why siblings can look similar but not identical.
Students compare living things to find what they have in common and what makes each one different. They explore how those differences help some plants and animals survive better than others.

Students learn where Earth fits in the solar system and how the planets move in predictable patterns. They also look at how Earth itself has changed over a very long time.
Students learn that land, water, air, and living things are each part of Earth and affect one another. A rainstorm filling a river, or roots breaking apart rock, are the kinds of connections students explore.
Students look at how people change the land, water, and air around them, and what happens when earthquakes, floods, or storms hit a community.

Students spot a real problem, sketch out ways to fix it, then test their ideas and improve them until the design works better.
Students explore how inventions shape daily life and how everyday needs push engineers to build new things. A new tool changes how people live, and how people live pushes engineers to create new tools.

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.
Science this year is hands-on. Students ask questions, run small experiments, and look for patterns in what they see. They study forces and motion, living things and their habitats, weather and the Earth, and they design simple solutions to everyday problems.
Notice things together. Watch how a ball rolls down a ramp, why ice melts faster in the sun, or how plants lean toward a window. Ask what students think will happen and why. A few minutes of wondering out loud builds the same thinking they use in class.
Start with the science practices in a short unit students will revisit all year, like observing, measuring, and recording. Then rotate through physical science, life science, and Earth science, ending with an engineering design project that pulls the practices back together.
Not really. The point is to think like a scientist, not to recite definitions. Students should be able to explain what they observed, what they think is happening, and what evidence backs it up. Vocabulary grows from doing the work, not from flashcards.
Two stand out. First, planning a fair test where only one thing changes at a time. Second, using evidence in an explanation instead of just describing what happened. Build short routines around both and revisit them in every unit.
Students take a real problem, like keeping a drink cold or building a stable tower, and try a few designs. They test, see what failed, and improve the next version. The lesson is the process of trying, measuring, and revising, not getting it right the first time.
By the end of the year, students should be able to ask a testable question, plan a simple investigation, collect data, and explain results using that data. If they can argue a point with evidence instead of opinion, they are ready.
Tie it to something they already like. Cooking is chemistry, sports are forces and motion, pets are biology, and rainy days are weather science. A short kitchen experiment or a walk that turns into a nature hunt usually brings back the curiosity.
