What does a student learn in StateMassachusetts,GradeGrade 2,SubjectScience?

Students ask questions about the natural world that can be tested, and figure out what makes a problem something science or engineering could actually solve.

Students draw or build a simple model (a diagram, a sketch, or a physical mock-up) to show how something in nature works or how a design they made is supposed to work.

Students come up with a question, plan a simple test to answer it, and collect what they find out. That gathered information helps them decide if their idea was right or wrong.

Students look at information collected from observations or simple experiments to spot patterns, like noticing which plant grew tallest or which material dried fastest.

Students use counting, measuring, and simple math to figure out patterns or answer questions about the natural world. A ruler, a tally chart, or a number line becomes a tool for thinking through what they observe.

Students look at what they observed or tested, then write or say why they think something happened. The explanation has to match the evidence, not just what they guessed at the start.

Students look at two possible explanations or solutions, then use what they observed or tested to argue which one holds up better.

Students gather facts from books, videos, or class observations, decide which information makes sense, and share what they found in words or pictures.

Students learn what everyday materials are made of and why they look, feel, or behave the way they do. They explore how tiny building blocks of matter interact to explain what they can see and touch in the world around them.

Students push, pull, and collide objects to see how things speed up, slow down, or change direction. They learn that a harder push moves something farther, and that objects stay put until a force acts on them.

Students explore how energy shows up in everyday life as light, heat, sound, or motion, and what happens when energy moves from one object to another.

Students explore how waves, like sound and light, carry energy from place to place. They look at real examples of waves at work, such as how a phone call travels or how a flashlight beam moves across a room.

Students look at how living things are built and how they work, from the smallest parts inside a plant or animal to the larger systems those parts make together.

Students learn how plants, animals, and other living things depend on each other to survive. They look at how food, water, and energy move through a community of living things.

Students look at physical traits like eye color, hair color, and height, then figure out which ones were passed down from parents and which ones differ from family member to family member.

Students look closely at how living things are alike and how they differ, then explore why some traits help animals and plants survive better than others.

Students learn where Earth sits in the solar system and how the sun, moon, and planets follow predictable patterns in the sky. They also look at evidence that shows how Earth itself has changed over a very long time.

Students explore how the ground, water, air, and living things around them connect and affect each other. A rainstorm filling a stream, or roots holding soil in place, are the kinds of relationships students look for.

Students look at how things people do (like building roads or cutting trees) change the land, water, or air, and how events like floods or earthquakes affect where and how people live.

Students identify a problem, sketch or build a solution, test it, and then improve it based on what they find out. This is how engineers work, and second graders practice the same process.

Students explore how inventions like phones or bridges change daily life, and how people's needs shape what engineers build next.
