Sorting and testing materials
Students look closely at everyday stuff like wood, metal, fabric, and plastic. They sort objects by what they notice and test which materials work best for a job, such as keeping something dry or holding weight.
This is the year science moves from noticing things to testing them. Students plan small experiments, like checking how light and water change a plant, and sort everyday materials by what they feel and do. They also look at how the land and water around them can shift fast in a storm or slowly over time. By spring, students can run a simple test, write down what they saw, and use it to back up an answer.
Students look closely at everyday stuff like wood, metal, fabric, and plastic. They sort objects by what they notice and test which materials work best for a job, such as keeping something dry or holding weight.
Students take things apart and rebuild them into something new from the same pieces. They also figure out which changes from heating or cooling can be undone, like melting ice, and which cannot, like baking an egg.
Students grow plants to see what light and water do. They learn how bees and other animals move pollen and seeds, and they compare the plants and animals that live in places like a forest, a pond, and a desert.
Students draw simple maps that show hills, rivers, lakes, and oceans in an area. They find out where water shows up on Earth and notice that it can be liquid or frozen solid.
Students gather evidence that some Earth events happen fast, like a volcano, and others happen slowly, like a canyon forming. They compare ways to slow wind and water from wearing away the land, such as planting grass or building a wall.
Students sort and describe everyday materials, like wood, plastic, and metal, by their physical properties. They explore how those properties determine what each material is good for.
Students sort everyday materials like wood, plastic, metal, and fabric by what they can observe: color, texture, hardness, and whether the material bends or breaks.
Students test materials like wood, metal, fabric, or plastic to figure out which one works best for a specific job. A raincoat needs to be waterproof; a bridge needs to be strong.
Taking apart an old object gives you the pieces to build something new. Students observe and explain how the same parts can make different things.
Heating and cooling can change materials in ways that can be undone (melted ice refreezes) or ways that cannot (a cooked egg won't go back to raw). Students sort real examples into each group and explain their reasoning.

Students learn how living things in a place depend on each other and on their surroundings to get food, shelter, and what they need to survive.
Students plan a simple experiment to find out what happens to plants when they get more or less light or water. They observe the results and draw conclusions about what plants need to grow.
Students draw or build a model showing how animals help plants survive, either by moving pollen from flower to flower or by carrying seeds to new places.
Students look at how animals and plants are built to survive in their habitat. A duck's webbed feet and a cactus's thick skin are examples of how living things are shaped to fit where they live.
Students look closely at plants and animals in different places, like a pond or a forest, and describe what makes each habitat's living things unique.

Students learn where Earth fits in space, studying the sun, moon, and stars and how they move and change across the day and the seasons.
Some Earth changes happen in seconds, like an earthquake or a flood. Others take thousands of years, like mountains forming. Students learn to compare fast and slow Earth events using books, photos, and other sources.
Students learn how water, wind, and land shape the Earth around them. They observe how rivers carve valleys, rain soaks into soil, and weather changes the landscape over time.
Students look at different ways people try to protect land from wind and water erosion, such as planting trees or building barriers, then decide which solutions seem to work best.
Students draw or build a simple map showing the landforms and bodies of water in a place, like hills, rivers, or lakes. The map is a model that captures what the land actually looks like.
Water covers most of Earth's surface and hides underground too. Students learn where water shows up on our planet, from oceans and rivers to ice and snow, and why the same water can be liquid or frozen solid depending on where it is.
