What does a student learn in StateNew Jersey,GradeGrade 4,SubjectScience?

Students learn to turn curiosity into a question that can actually be tested or a problem that can be solved by building something. This is how science and engineering both get started.

Students build or draw a model (a diagram, a sketch, or a physical object) to show how something in nature works or how a designed object is put together. The model helps explain what is hard to see or describe in words alone.

Students plan a test, collect data, and use what they find to check whether an idea holds up. This is the core of doing science rather than just reading about it.

Students look at data from their experiments and ask: what does this actually show? They find patterns, like which plant grew tallest or which material got hottest, and use those patterns to draw a conclusion.

Students use numbers, measurements, and basic math to back up their ideas in science. Instead of just describing what they observe, they count, measure, or calculate to make their reasoning more solid.

Students take facts from observations or experiments and use them to explain why something happened or how something works. The explanation has to be backed by evidence, not just a guess.

Students look at two different explanations or solutions and use evidence to argue which one holds up better. They back their position with data or observations, not just opinion.

Students read science texts, diagrams, and data to find information, judge whether it makes sense, and share what they learned clearly with others.

Students examine what everyday materials are made of at a level too small to see, then use that to explain why things behave the way they do, like why ice melts or why salt dissolves in water.

Students study why objects speed up, slow down, or stay still. They learn how pushes and pulls change the way things move, and why a ball rolling across the floor eventually stops.

Students study how energy moves from one place to another and changes form, like heat warming a cold object or light powering a solar toy. Energy is never lost; it just shows up somewhere new.

Students study how waves like sound and light move energy from one place to another. They also look at how waves carry information, like how a radio signal travels or how a knock on a door makes sound across a room.

Living things are made of smaller parts that work together. Students study how those parts, from tiny cells up to whole body systems, are built and what they do.

Students trace how energy from the sun moves through a food chain and how matter like water and nutrients cycles back through living things. They also look at how plants, animals, and other organisms depend on and affect each other in the same habitat.

Students look at how traits like eye color or height pass from parents to offspring, and why siblings can look similar but not identical.

Students look at how living things share basic traits and how, over long stretches of time, species change to survive in their environments.

Students study where Earth sits in the solar system and how the sun, moon, and planets move in predictable patterns. They also look at how Earth itself has changed over a very long time.

Students look at how land, water, air, and living things work together on Earth. They explore what happens when one of those parts changes and how it affects the others.

Students look at how things like building roads or burning fuel change the land, water, and air around us. They also study how earthquakes, floods, and storms affect where and how people live.

Students identify a real problem, sketch or build a solution, then test it and improve it based on what they find out.

Engineers build things that change how people live, and the way people live shapes what engineers build next. Students explore how inventions affect daily life and how needs in a community drive new solutions.
