What does a student learn in StateTennessee,GradeGrade 3,SubjectScience?

Students learn that matter is everything around them that takes up space and has weight. They explore how materials like wood, water, and metal can change or interact when mixed, heated, or cooled.

Students learn why objects move, stop, or change direction by exploring pushes, pulls, and other forces. They also investigate what keeps objects stable and what makes them tip, slide, or stay put.

Students learn what energy is and how it moves or changes things. They look at light, heat, and motion to understand where energy comes from and what it does.

Living things are made of parts that work together to keep them alive. Students learn how plants and animals are built, how those structures help them survive, and how living things grow and reproduce.

Students learn how living things depend on each other and their surroundings to survive. They explore how plants, animals, and the environment swap energy and resources to keep an ecosystem running.

Students sort real animals and plants by their traits, spotting patterns that show how living things are related, how they change over generations, and why some survive while others don't.

Students learn why the sky looks different at different times of year, why seasons change, and how the sun, moon, and stars follow predictable patterns day to day.

Students learn how weather, water, and land interact to shape the world around them, from rainstorms filling rivers to wind wearing down rocks over time.

Students learn how humans use natural resources and how their choices can protect or damage land, water, and living things.

Students learn to spot a problem, come up with solutions, and test whether their ideas actually work. It's the same thinking process engineers use when they build or fix something in the real world.

Solids, liquids, and gases are all made of tiny particles too small to see. Students draw or build a model to show how those particles are arranged differently in each state of matter.

Heating and cooling can change a substance in two ways. Some changes, like melting ice or freezing water, can be undone. Others, like baking or burning, are permanent. Students learn to tell the difference.

Some properties of a material, like color or texture, stay the same no matter what you do to it. Others, like shape or temperature, can change. Students use those properties as clues to identify what a material is made of.

Students learn why objects can push or pull each other without touching. Magnets attract metal across a gap, static electricity makes a balloon stick to a wall, and gravity pulls a dropped ball to the ground.

Students observe everyday sources like a ringing bell, a lamp, or a warm sidewalk to gather proof that energy is at work. The goal is to notice how sound, light, and heat show up in the world around them.

Students build a simple circuit and show how electricity moves through it to power a light or buzzer. The model shows that energy travels from one place to another through connected parts.

Magnets push and pull objects without touching them. Students test how the strength and position of a magnet changes where an object moves or rests.

Students look at diagrams showing how different living things grow and change over a lifetime. They compare life cycles across species, including humans, and notice what makes each one unique.

Plants and animals have body parts built for staying alive. Students study how those parts, inside and out, help creatures find food, grow, protect themselves, and have offspring, whether they live on land or in water.

Animals like wolves, ants, and geese live and work in groups. Students study how those groups are organized, with some members playing different roles and others sharing the same job, to explain why living together helps animals survive.

When a habitat changes naturally, like a drought drying out a pond, some animals survive and others don't. Students use real examples to explain why a changing environment helps certain creatures and hurts others.

Students look at real examples to figure out how human activity, like farming or building, changes the variety of plants and animals living in an area.

Students sort the sun's neighbors (planets, moons, asteroids, and comets) into groups based on what they look like and how they move through space.

Students draw or diagram how Earth's parts connect: how rain soaks into soil, how plants hold ground together, or how wind moves water. The goal is to show that land, life, water, and air affect each other.

Students map how water moves from oceans and lakes into the air, then falls back to Earth as rain or snow. They show how sunlight is the engine that keeps this cycle going.

Students read weather data from tables and graphs to spot patterns in rain, temperature, clouds, and wind. Those patterns help them predict what the local weather is likely to do next.

Students use real temperature and rainfall data to compare climates around the world, from frozen polar regions to hot, rainy tropical ones, and explain what makes each region's weather pattern distinct.

Students look at real tools people use to stay safe during floods, earthquakes, and other natural hazards, then judge how well those solutions actually work.

Students come up with a design that solves a real problem, like keeping something dry in the rain, while following specific rules about size, cost, or materials they can and cannot use.

Students find facts or test results that back up why their design idea would work. They use that evidence to explain their solution, not just describe it.
