Heat, particles, and matter
Students start the year looking at what happens to tiny particles inside a substance when it heats up or cools down. They build models to explain why ice melts, water boils, and metal spoons get hot.
This is the year science zooms in on the building blocks: tiny particles that explain heat, cells that explain living things, and rock layers that explain Earth's history. Students build models, run investigations, and use evidence to back up their thinking. They explain how heat moves, how waves bounce or pass through stuff, and how water and air shape weather. By spring, students can sketch how a cell works and explain why the same rocks show up on different continents.

Students plan experiments to see how energy moves between objects and design something that keeps a drink hot or cold. They also study how light and sound waves bounce off, pass through, or get soaked up by different materials.
Students use microscopes and models to show that every living thing is built from cells. They explain how cells team up to form body systems and how the brain takes in signals from the senses.
Students read layers of rock the way a parent might read a stack of old photos. They use fossils and the shapes of continents as evidence that Earth's surface has shifted over a very long time.
Students track how water and air move around the planet, powered by the sun and gravity. They collect weather data and explain why some regions are rainy, some are dry, and storms form where they do.
Students close the year by studying earthquakes, floods, and severe storms. They look at past data to predict where hazards are likely and consider how people design buildings and warning systems to stay safer.
Students build a diagram or model showing what happens to the particles inside a substance when it heats up or cools down, including when it melts, freezes, or boils.

Students design and build a device to control heat transfer, then test whether it works. Think of insulating a cold drink to keep it from warming up, or building a surface that absorbs heat as fast as possible.
Students design an experiment to find out how the type and amount of a material affect how much its temperature changes when heat is added or removed.

Waves hit a surface and do one of three things: bounce back, pass through, or get soaked up. Students model how light or sound behaves differently depending on the material it meets, like glass, wood, or water.

Students investigate whether living things are made of one cell or many. They gather evidence by observing samples under a microscope and comparing single-celled organisms with plants, animals, and other multi-celled life.
Students build a model (drawing, diagram, or physical model) showing what a cell does and how its parts, like the nucleus or membrane, each play a specific role in keeping the cell working.
Students explain how the body's major systems (like the digestive or nervous system) work together to keep a person alive, using evidence to back up their reasoning. Each system is made of specialized cells doing a specific job.
Students learn how the brain receives signals from the senses and uses them to react in the moment or store as memories. This covers sight, sound, touch, taste, and smell.

Rock layers act like a timeline. Students study stacked rock formations to explain how scientists divide Earth's 4.5-billion-year history into periods, using older layers buried deeper and newer layers closer to the surface.

Students build a diagram or model showing how rock, water, and air move through Earth's systems over time, and trace what source of energy, like the sun or heat from inside the planet, keeps those cycles going.
Geoscience processes like erosion, volcanic eruptions, and earthquakes reshape Earth's surface over time. Students explain how those changes can happen in seconds or over millions of years, and across a backyard or an entire continent.
Students study maps of fossils, rock layers, and ocean floor ridges to figure out how Earth's continents have shifted over millions of years. The patterns in the data show where tectonic plates once met or pulled apart.
Students draw or diagram how water moves from oceans and lakes into clouds, then falls as rain or snow, and flows back downhill. The driving forces are sunlight, which pulls water into the air, and gravity, which pulls it back down.
Students track how air masses move and collide to explain why the weather changes. They collect real data, like temperature and pressure readings, to back up what they observe.
Students build a diagram or model showing why some parts of Earth get more sun than others, then explain how that uneven warmth, combined with Earth's spin, drives wind and ocean current patterns that shape the climate of each region.

Students study heat and how particles move, waves, cells and body systems, and Earth science like weather, water, rocks, and plate motion. The year leans heavily on building models and running investigations to explain how things work, not just memorizing facts.
Ask students to explain a diagram or model from class in their own words. Point out everyday examples like steam from a kettle, ice melting in a drink, or weather on the news. Five minutes of explaining out loud beats rereading a textbook.
Some labels help, but the bigger goal is explaining what each part does and how cells work together to keep a body running. If students can sketch a cell and describe what each piece does in plain language, they are on track.
Students should be able to build a simple model or explanation for a science question, back it up with evidence, and connect ideas across topics. For example, linking heat transfer to weather patterns, or cells to body systems.
Many teachers start with matter and thermal energy because the particle model supports later units on weather, climate, and water cycling. Cells and body systems can sit as a self-contained block, and Earth history and plate motion work well near fossils and rock strata.
Particle motion and kinetic energy trip up students because the particles are invisible. Plate tectonics and the geologic time scale also need extra time, since the scales feel abstract. Plan for repeated modeling and hands-on demos in these areas.
Quite a bit. Standards ask students to plan investigations, collect data, and design devices, such as a container that keeps a drink cold. Short, repeatable investigations across the year build more skill than a few large projects.
Students should be comfortable reading a science diagram, describing a cause and effect with evidence, and explaining ideas like heat transfer, the water cycle, and how cells make up a body. Confidence with graphs and data tables matters too.
