What does a student learn in StateKansas,GradeGrade 4,SubjectScience?

Students study how energy moves and changes form, like when a moving ball pushes another object or sunlight warms a surface. They learn what energy does, not just what it is.

Students study how waves carry energy and information, from sound traveling through air to light bouncing off objects. This leads into how phones, radios, and cameras use those same wave properties to send and store information.

Students learn how plants and animals are built to survive. They study body parts like roots, lungs, and eyes, and explain what each one does to keep the organism alive.

Students learn how Earth moves through space and how the sun, moon, and stars follow patterns in the sky. That includes day and night cycles, seasons, and the shapes the moon seems to take each month.

Rocks, water, wind, and living things all shape the land over time. Students study how these forces work together to change Earth's surface through processes like erosion, weathering, and the water cycle.

Students study how humans use natural resources like water, soil, and land, and how those choices can protect or damage the environment. They also look at how people reduce the impact of natural hazards like floods or earthquakes.

Students explain why a faster-moving object has more energy than a slower one. They use observations or data as evidence to back up their explanation.

Students observe everyday examples, like a warm lightbulb or a ringing bell, to show that energy moves from one place to another. Sound, light, heat, and electricity are the main ways that transfer happens.

Students watch what happens when objects crash into each other, then predict how the energy changes. They ask questions about why a harder hit makes a bigger change than a softer one.

Students design and test a device that changes energy from one form to another, like turning movement into electricity or light into heat. Then they use what they learn from testing to improve it.

Waves carry energy through water, sound, and light. Students model how waves move, measuring how tall a wave rises (amplitude) and how far apart the peaks are (wavelength), and show how a wave can push or rock an object in its path.

Students explain why you can see a ball, a chair, or a face: light bounces off the object and travels into the eye. They build or draw a model showing that path from object to eye.

Students design and compare different ways to send information using patterns, like light signals or sound codes. The goal is to figure out which method works best.

Students study the body parts plants and animals have on the outside and inside, such as roots, lungs, or bones, and explain how those parts help a living thing survive, grow, and reproduce.

Students use a diagram or model to show how an animal's senses pick up information, the brain sorts it out, and the animal reacts. A dog hears a sound, processes it, and runs toward it.

Students look at rock layers and the fossils inside them to figure out how a place has changed over millions of years. A cliff or canyon is basically a timeline you can read with your eyes.

Students observe rocks, soil, and land to find evidence of how wind, water, ice, or plant roots slowly break things apart or carry material away. The goal is to spot patterns in how fast or slow that change happens.

Students read maps to find patterns in where mountains, valleys, volcanoes, and ocean trenches show up on Earth. The goal is to see that these features aren't random; they cluster in specific places.

Students learn where energy comes from, such as sunlight, wind, and oil, and look at what happens to the land, water, or air when people use those resources.

Students think up and compare different ways to protect people from natural events like floods, earthquakes, or erosion. The goal is to weigh which solution works best, not just pick one.
