What does a student learn in ?

This is the year science gets hands-on with energy and how the world changes over time. Students explore how moving things carry energy, how sound and light travel, and how a bouncing ball or flicked switch passes energy from one place to another. They also study how plants and animals are built to survive and how wind, water, and ice slowly reshape the land. By spring, students can sketch a simple model showing how light bounces off an object and into the eye.

  • Energy and motion
  • Light and sound
  • Plant and animal parts
  • Weathering and erosion
  • Fossils and landforms
  • Design challenges

Year at a glance
How the year usually goes. Every school and district set their own curriculum, so treat this as a guide, not official pacing.
  1. 1

    Energy in motion and collisions

    Students start the year looking at how fast things move and what happens when they crash. They run small tests with rolling balls or carts and use what they see to explain why a faster object hits harder.

  2. 2

    Sound, light, and waves

    Students explore how energy travels through sound, light, heat, and electricity. They model waves with ropes or water, figure out how light bouncing off objects lets the eye see them, and compare ways to send messages using patterns.

  3. 3

    Designing an energy device

    Students put the year's energy ideas to work. They define a small design problem, sketch options, then build and test a device that changes one kind of energy into another, like a windmill that lights a bulb.

  4. 4

    Plants, animals, and senses

    Students study the parts of plants and animals that help them survive, from roots and leaves to eyes and ears. They model how an animal takes in information through its senses, processes it in the brain, and acts on it.

  5. 5

    Earth's changing surface

    Students read the story Earth tells through rock layers and fossils. They run small tests with water, wind, and ice to see how land wears down over time, and use maps to spot patterns in mountains, rivers, and coastlines.

  6. 6

    People and the environment

    Students wrap up the year by looking at where energy and fuels come from and how human choices affect the land, water, and air. They work with local sources and community partners to design a solution to a real environmental problem near school.

    WA 4.LS1

    Students build or draw models of plants and animals to show how body parts work. They explain what each structure does inside and outside the organism, like how roots pull in water or how bones hold a body upright.

  • Construct an argument that plants and animals have internal and external…

    4-LS1-1

    Plants and animals have body parts inside and out that help them live and grow. Students look at structures like roots, lungs, or eyes and explain what job each one does.

  • Use a model to describe that animals receive different types of information…

    4-LS1-2

    Animals take in information through their senses, process it in the brain, and react. Students use a model to show how this works, like explaining why a dog's ears perk up at a sound before it turns to look.

Earth and Space Sciences
  • Use evidence to show and explain how Earth’s features have changed over time

    WA 4.ESS1

    Students look at rocks, landforms, and fossils to figure out how Earth's surface has shifted, eroded, or built up over millions of years. Evidence like layered rock or ancient shells tells the story of how a place used to look.

  • Identify evidence from patterns in rock formations and fossils in rock layers…

    4-ESS1-1

    Rock layers and fossils act like a record of Earth's past. Students read patterns in those layers to explain how a landscape, like a canyon or hillside, has changed over millions of years.

  • Use investigation, evidence

    WA 4.ESS2

    Students investigate rocks, landforms, and bodies of water to find patterns in how Earth's surface looks and why it changes over time. Evidence from the natural world, not just a textbook, drives the explanation.

  • Make observations and/or measurements to provide evidence of the effects of…

    4-ESS2-1

    Rocks, soil, and land slowly break apart and shift over time. Students observe and measure how water, wind, ice, or plants wear down and move earth materials, then use what they find as evidence of how land changes.

  • Analyze and interpret data from maps to describe patterns of Earth’s features

    4-ESS2-2

    Reading a map, students look for patterns in where mountains, valleys, volcanoes, and ocean trenches show up. The goal is to notice that these features are not scattered randomly but tend to cluster in the same regions.

Common Questions
  • What does science look like this year?

    Students study energy and motion, light and sound waves, plants and animals and how they survive, and how Earth changes over time. A lot of the work is hands-on. Students build things, test them, watch what happens, and explain why.

  • How can I help with science at home?

    Talk about what students notice outside. Watch how rain moves dirt in the yard, how a flashlight beam bounces off a mirror, or how fast a ball rolls down different ramps. Ask what they think will happen before they try something, then ask why it happened.

  • My child says science is mostly building stuff. Is that right?

    Yes, and that is on purpose. Students design a small device, test it, see what fails, and try again. Building a marble run or a paper cup phone at home is the same kind of thinking.

  • How should I sequence the year?

    Many teachers start with energy and motion in the fall, move to waves and light in the winter, and finish with life science and Earth science in the spring. Engineering design fits inside each unit, not as a separate block.

  • What usually needs the most reteaching?

    Two ideas often need a second pass. First, that energy moves from one place to another rather than disappearing. Second, that we see objects because light bounces off them and into our eyes. Both take more than one investigation to stick.

  • How does engineering fit into a science year?

    Students define a problem, list what counts as success, build a prototype, and run fair tests where only one thing changes at a time. Tie it to a science unit so the design choices are grounded in what students just learned about energy, waves, or erosion.

  • What is the environmental sustainability work about?

    Students look at a real local issue like water quality, waste, or habitat on the school grounds. They gather evidence from more than one source, including tribal and community perspectives, and propose a solution they can actually try.

  • How do I know students are ready for fifth grade science?

    By spring, students should be able to plan a fair test, collect data, and write an explanation that uses that data as evidence. They should also be able to read a simple map or diagram and describe the pattern they see.

  • Does my child need to memorize a lot of science vocabulary?

    Some words matter, like energy, wave, erosion, and fossil. Understanding what the words mean in a real example matters more than spelling them. Ask students to explain a term using something from the kitchen, the yard, or a walk.
