What does a student learn in StateConnecticut,GradeGrade 3,SubjectScience?

Students learn to ask questions that science can actually test and spot problems that engineering can solve. It's the habit of turning curiosity into something worth investigating.

Students build or draw a simple model (like a diagram or labeled sketch) to show how something in nature works or how a design solves a problem.

Students plan a test, collect information, and check whether their idea holds up. This is how scientists figure out if they are right.

Reading a chart or table, students look for patterns in the numbers or results and explain what those patterns mean.

Students use counting, measuring, and simple math to back up what they notice in science. Instead of just saying something seems bigger or heavier, they use numbers to show it.

Students use what they observed or measured to explain why something happened. The explanation has to be backed by real evidence, not just a guess.

Students look at two different explanations or solutions, then use facts and observations to argue which one holds up better. Think of it as a science debate backed by real evidence, not just opinion.

Students read scientific information from books, diagrams, or charts, decide what it means, and explain it to others in words or pictures.

Students look closely at what everyday materials are made of and explore why some substances mix, dissolve, or change when they interact with each other.

Students explore how pushes and pulls make objects speed up, slow down, or change direction. They look at what keeps things steady and what sets them moving.

Students explore how energy shows up in different forms, like heat, light, and sound, and trace where it goes when something moves, glows, or makes noise. Energy doesn't disappear; it just changes from one form to another.

Students study how waves, like sound and light, carry energy and information from one place to another. They look at real examples, such as how a phone screen or a speaker works.

Students look at how living things are built and how they work, from the tiny cells inside them to the organs and body systems those cells make up.

Students trace how food, water, and energy move through a living community, from plants to animals to decomposers. They also look at how organisms depend on each other to survive.

Students look at traits like eye color, leaf shape, or fur pattern and figure out which ones got passed down from parents and which ones vary across a family.

Students compare living things to spot what they share and what makes each one different. That investigation builds toward understanding why life on Earth looks the way it does today.

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

Students study how Earth's land, water, air, and living things connect and affect each other. They look at how a rainstorm shapes soil, how plants filter air, and how one change ripples through the rest.

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

Students spot a problem, sketch out a few ways to fix it, then test their ideas and improve them until one works well enough to use.

Students explore how inventions change everyday life and how the needs of a community shape what engineers build next.
