What does a student learn in StateNew Hampshire,GradeGrade 3,SubjectScience?

Students practice turning curiosity into testable questions, like wondering why ice melts faster in one spot than another. They also learn to describe a problem clearly enough that a solution can actually be designed and tested.

Students draw or build a model (like a diagram or a physical object) to show how something in nature works or how a design they built is supposed to function.

Students plan a simple test, collect data from it, and use what they find to check whether their idea holds up.

Students look at data from an experiment, then explain what it shows and find patterns, like noticing which plant grew tallest or which material got hottest.

Students use numbers, measurements, and simple calculations to back up what they observe and figure out in science. A measurement or a count becomes evidence.

Students take what they observed or measured and write an explanation that shows why something happened. The explanation has to be backed by evidence, not just a guess.

Students look at two different explanations or solutions, then use what they observed or measured to argue which one holds up better. The focus is on the evidence, not just the opinion.

Students read simple science texts, decide if the information makes sense, and share what they learned in writing or conversation.

Students learn what objects are made of and why materials behave the way they do, like why ice melts or why some things dissolve in water. They use hands-on investigation to explain everyday physical changes.

Students test what happens when they push or pull objects of different sizes and weights. They learn why things speed up, slow down, or stay still based on the size of the force applied.

Students explore how energy shows up in different forms, like light, heat, and sound, and track what happens when it moves from one object to another. Energy doesn't disappear; it just changes form.

Students explore how waves carry energy and information from place to place. They look at examples like sound, light, and water waves to see how waves move and how people use them to send signals.

Students look at how living things are built and how they work, from the tiny cells that make up a body to the larger systems those cells form, like a heart pumping blood or roots pulling up water.

Students trace how energy from the sun moves through an ecosystem, from plants to the animals that eat them. They also look at how living things in a community depend on each other to survive.

Students look at plants or animals across generations to understand which traits get passed down from parents to offspring and which ones differ. A dog might inherit its parent's coat color but vary in size.

Students look at how living things are alike and how they differ, then explore why those differences help some survive better than others.

Students explore where Earth sits in the solar system and how the sun, moon, and planets move in predictable patterns. They also look at how Earth itself has changed over a very long time.

Students look at how land, water, air, and living things affect each other. They might explore how rain shapes the ground or how plants hold soil in place.

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

Students spot a problem, sketch a few ways to fix it, then test and improve their best idea until it works better.

Students look at how inventions like bridges or water systems change daily life, and how the needs of a community push engineers to build new things in return.
