Thinking like a scientist
Students start the year learning how to ask testable questions, plan small investigations, and record what they notice. Expect them to come home talking about patterns they spotted and reasons they think something happened.
This is the year science becomes something students actually test, not just read about. Students ask a real question, plan a simple investigation, and use what they find to explain how the world works. They look at forces and motion, living things and their habitats, and patterns in weather and the sky. By spring, students can run a small experiment, record what happened, and explain the results using their own data.
Students start the year learning how to ask testable questions, plan small investigations, and record what they notice. Expect them to come home talking about patterns they spotted and reasons they think something happened.
Students push, pull, and watch how objects move. They explore how energy shows up as heat, light, and sound, and they look at how waves carry sound from one place to another.
Students study how plants and animals grow, what they need to survive, and how traits pass from parents to offspring. They compare animals in different habitats and notice what helps each one fit in.
Students track weather patterns, look at how land and water shape the planet, and think about how people affect rivers, soil, and air. They also learn how communities prepare for storms and other natural hazards.
Students end the year as young engineers. They name a real problem, sketch a possible fix, build a simple version, and improve it after testing. Expect taped-together prototypes and stories about what worked and what flopped.
Students practice turning everyday curiosity into testable questions. They learn to spot the difference between a question science can investigate and a problem an engineer might solve.
Students draw, build, or act out models to show how something in nature works or how a design solves a problem. The model helps them explain what they observe and test their thinking.
Students plan a simple test, collect information from it, and use what they find to check whether their idea holds up.
Students look at collected data, such as temperature readings or plant growth measurements, and find patterns that help explain what happened in an experiment.
Students use counting, measuring, or simple math to help explain what they observed in a science investigation. Numbers make patterns and results easier to see and compare.
Students take what they observed or measured and write an explanation for why it happened, using that evidence to back up their thinking.
Students look at two different explanations for the same thing, then use what they observed or tested to argue which one holds up better.
Students read about science topics and share what they learned, using drawings, words, or charts. They also check whether information they find is accurate before passing it on.

Students examine what everyday materials are made of and how those materials behave, change, or interact with each other. This builds toward explaining why ice melts, why some things dissolve in water, and how matter behaves in the physical world.
Students test how pushes and pulls make objects speed up, slow down, or change direction. They learn that a harder push moves something farther, and that balanced forces keep an object still.
Students explore how energy moves and changes form, like heat traveling from a hot pan to a cold room or light turning into warmth from the sun. They learn that energy shifts from place to place but is never lost.
Students explore how waves carry energy and information from one place to another. They look at examples like sound, light, and water ripples to understand how waves move and how people use them to send signals.

Students learn how living things are built and how they work, from the tiny cells inside them to the larger systems those cells form. They look at real examples to see how structure and function connect.
Students trace how energy from the sun moves through a food chain and how nutrients cycle back into the soil. They also look at how plants, animals, and other organisms depend on each other to survive.
Students look at family traits like eye color, hair texture, or plant leaf shape to figure out which ones get passed down from parents to offspring and which ones vary from one generation to the next.
Students look at how living things are alike and how they differ, then explore why those differences matter for survival over time.

Students identify a real problem, sketch or build a solution, then test it and improve it based on what they learn. The goal is a design that works better each time they try.
Students explore how inventions change daily life and how the needs of everyday life push engineers to build new things. A new tool can reshape a community, and a community's problems can spark the next invention.

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 ask real questions and run small experiments to find answers. They study forces and motion, living things and habitats, weather and the planet, and they try simple engineering challenges like building something that solves a problem.
Pay attention to questions students ask about how things work, then look for the answer together. A walk outside, a kitchen experiment, or watching what a pet does all count. Asking why and how matters more than knowing the right answer.
No. Cups, water, ice, paper, tape, rubber bands, magnets, and rocks from the yard are plenty. The point is to notice patterns and explain what happened, not to buy a kit.
Most teachers anchor each quarter in one big strand: physical science, life science, earth science, and an engineering project. Weave the practices like asking questions, planning investigations, and arguing from evidence into every unit instead of teaching them on their own.
Planning a fair test and arguing from evidence are the hardest. Students often jump to a conclusion before checking the data. Short, repeated practice with sentence frames like I think this because helps more than one big lesson.
Students should ask a testable question, plan a simple investigation, record what they see, and explain results using evidence. They should also be able to read a short science article and pull out the main idea.
No. Most of the year is about doing science, not memorizing it. Students gather evidence, draw models, and explain what they think is happening. Knowing some vocabulary helps, but reasoning from what they observe matters more.
Look for students who can design a simple test, collect data without prompting, and back up a claim with what they saw. If they can sketch a model that shows how something works and revise it after new evidence, they are ready.
