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

Students come up with questions that can be tested with an experiment, and problems that could be solved by building or designing something.

Students draw or build a simple model (like a diagram or a physical mockup) to show how something in nature works or how a design would function. The model helps explain an idea that's hard to see just by looking.

Students plan a simple test, carry it out, and record what they find. The goal is to answer a question with real evidence, not a guess.

Students look at collected data, such as a chart or tally of measurements, and explain what it shows. They spot patterns, like which result happened most often or how something changed over time.

Students use counting, measuring, and simple math to back up what they notice in science. A chart or a number helps explain why something happened.

Students back up their explanations with evidence from what they observed or tested. They use that evidence to show why something happened or how a problem could be solved.

Students look at two different explanations or solutions, then use evidence to argue which one works better. The focus is on backing up a choice with real reasons, not just opinion.

Students read simple science texts, look at diagrams and charts, and share what they learned. They practice deciding whether information makes sense and explaining findings in their own words.

Students learn why things look, feel, and behave the way they do by studying what matter is made of and how tiny particles interact. This is the foundation for explaining everyday physical events.

Students push, pull, and observe how objects speed up, slow down, or stay still. They learn why a ball rolls farther on a hard floor than on grass, and what it takes to stop something that's already moving.

Students explore how energy shows up in everyday forms like light, heat, and sound, then trace what happens when energy moves from one object to another. They learn that energy changes form but doesn't disappear.

Students explore how waves move energy from place to place, like sound traveling through air or light bouncing off a mirror. They look at how waves carry information, the way a phone call or a walkie-talkie sends a voice across a distance.

Students learn how living things are built and how they work, from the tiny parts inside a plant or animal all the way up to the organs and systems that keep it alive.

Students explore how living things in a habitat depend on each other for food and shelter. They look at how plants, animals, and other organisms pass energy and materials along a food chain.

Students look at plants or animals across generations to see which traits get passed from parents to offspring and which ones vary. A puppy might have its mother's coat color but different ear shape.

Students look at how different living things (plants, animals, insects) share some features and differ in others, and begin to explore why those differences matter for survival.

Students study where Earth sits in the solar system and how it moves around the sun. They also look at patterns in the sky, like why day follows night, and explore how Earth itself has changed over a long span of time.

Students learn that Earth has four main parts: the land, the water, the air, and all living things. They look at how these parts affect each other, like how rain fills rivers and rivers shape the ground.

Students explore how people change the land, water, and air around them, and how events like floods or storms affect where and how people live.

Students spot a problem, sketch out ideas for fixing it, then test their designs and improve them based on what they learn.

Students explore how the tools and machines people invent change everyday life, and how the needs of everyday life shape what engineers build next.
