What does a student learn in StatePennsylvania,GradeGrade 1,SubjectScience?

Students spot something puzzling in the world around them and turn it into a question worth investigating. In science, that curiosity is where every experiment begins.

Students draw or build simple models to show how something in the world works, like a diagram of the sun and clouds to explain weather.

Students pick a question, plan a simple test, and collect information to figure out why something happens or whether a solution works.

Students look at information they collected, spot patterns in it, and use what they find to explain why something happened or to improve a design they built.

Students use numbers, counting, or simple measurements to describe something they observe in nature, like how tall a plant grows or how many times a bird visits a feeder.

Students use what they observed or tested to explain why something happened or to come up with a way to fix a problem.

Students look at two different explanations for something they observed and decide which one the evidence actually supports. They practice backing up their choice with what they saw or tested, not just what they think.

Students share what they learned in science using words, drawings, and other tools. They also look at information from books or pictures to figure out what it means.

Students sort and describe everyday objects by their physical properties, such as color, texture, hardness, and whether they sink or float. This is the starting point for understanding why materials behave the way they do.

Students push, pull, and move objects to see how forces change the way things go faster, slower, or in a different direction.

Students explore how energy shows up in everyday life, from a light bulb glowing to a ball rolling downhill. They look at how energy moves from one place or object to another.

Students explore how waves, like sound and light, carry energy and information from one place to another. They look at everyday examples, like how a voice travels across a room or how light lets us see.

Students look at the parts of plants and animals, like roots, leaves, or legs, and learn what each part does to keep the living thing alive.

Students learn how living things in a habitat depend on each other for food and shelter. They explore how energy moves from plants to animals and how matter, like water and nutrients, cycles through the environment.

Students look at how traits like eye color or curly hair get passed from parents to children, and notice that siblings can share some traits but not others.

Students look at living things around them and notice what makes each one unique, then start to ask why different plants and animals look and act the way they do.

Students learn why the sun appears to move across the sky each day and how day and night happen. They also look at patterns in weather and seasons to understand how Earth changes over time.

Students learn that Earth has four connected layers: solid ground, water, air, and living things. They observe how these layers affect each other, like how rain soaks into soil or wind moves water.

Students look at how people change the land, water, and air around them, and what happens when storms, floods, or other natural events disrupt daily life.

Students learn where food and materials like cotton or wood come from and how farms affect the land, water, and animals around them.

Students look at how plants, animals, water, and land connect in a local environment, then explore what happens when something in that system changes.

Students look at everyday choices, like how people use water or electricity, and consider whether those choices help or hurt the natural world around them.
