Becoming young scientists
Students learn how scientists work. They ask questions they can test, use simple tools safely, measure with rulers and cups, and share what they found out in pictures and words.
What does a student learn in
This is the year science becomes hands-on investigation. Students plan small experiments, measure with rulers and other simple tools, and write down what they notice. They start sorting objects by properties like weight and texture, watching how pushes and pulls change motion, and tracking weather, plants, and animals in their habitats. By spring, students can run a simple test, record their findings, and explain what happened using their own data.
- Hands-on experiments
- Measuring and tools
- Properties of matter
- Pushes and pulls
- Weather patterns
- Plants and animals
- Earth and sky
Year at a glance
How the year usually goes. Every school and district set their own curriculum, so treat this as a guide, not official pacing.
- 1
- 2
Matter and everyday energy
Students sort objects by what they feel and look like, such as hard, soft, heavy, or light. They notice how heat, light, and sound move from one thing to another.
- 3
Pushes, pulls, and motion
Students play with ramps, balls, and toy cars to see how a push or pull changes how something moves. They watch for patterns and start to predict what will happen next.
- 4
Earth, weather, and sky
Students track the weather, look at land and water around them, and notice patterns in the sun, moon, and stars. They talk about how people can help or hurt the places they live.
- 5
Living things and their homes
Students study plants and animals and the places they live. They look at how creatures find food, raise young, and have body parts that help them survive where they belong.

Scientific and Engineering Practices
Scientific and Engineering Practices
-
Scientific Investigation
Students plan and carry out simple science investigations, choosing the right tools and staying safe, to answer a question they can actually test.
-
Scientific and Engineering Practices
Students ask questions about the world around them, then test ideas, build simple models, and look at what the results show. This is the foundation of how scientists and engineers actually work.
-
Tools and Measurement
Students use rulers, measuring cups, and thermometers to gather and record numbers during science activities. The measurements follow standard metric units so results can be compared and checked.
-
Communicate Findings
Students explain what they found in a science activity and back it up with data. They might write it down, say it out loud, or show it in a drawing or chart.
-
Recurring Themes and Concepts
Students look for ideas that show up across all areas of science, like how things connect in a system, how patterns repeat, or how one event causes another.

Matter and Energy
Matter and Energy
-
Properties of Matter
Students learn that everything around them, from a rock to a glass of water, has properties like color, texture, and weight that can be measured. Those properties determine how matter is sorted, changed, and put to use.
-
Energy Forms and Transfers
Energy can make things move, heat up, glow, or make sound. Students explore how energy moves from one object to another, like a rolling ball knocking over a block or sunlight warming a surface.

Force, Motion, and Energy
Force, Motion, and Energy
-
Forces and Motion
Students push or pull objects and observe what happens: heavier objects need more force to move, and stronger pushes make things go faster or farther.
-
Patterns of Motion
Students watch how objects move, measure how far or fast they go, and predict what will happen next. They look for patterns, like a ball always rolling the same way down a ramp.

Earth and Space Sciences
Earth and Space Sciences
-
Earth's Systems
Students learn that Earth is made of connected layers and parts: the ground beneath them, the water in rivers and oceans, the air around them, and all living things. They explore how those parts affect each other.
-
Weather and Climate
Students track how weather changes day to day and season to season, then look at what shapes the climate of a place over time, including how human activity plays a role.
-
Space and the Solar System
Students learn how the sun, moon, and planets move in predictable patterns and how those movements shape what we see from Earth, like day and night or the changing shape of the moon.

Organisms and Environments
Organisms and Environments
-
Organisms and Environments
Students learn how living things (plants, animals, and insects) are built and behave in ways that help them survive where they live. A cactus stores water; a bird builds a nest. The body parts and habits of an organism fit the place it calls home.
-
Ecosystems
Students learn how plants, animals, and other living things in a place depend on each other for food and survival. They look at what happens when one part of that system changes.
-
Heredity and Reproduction
Students learn that living things have offspring that look similar to their parents. Plants and animals pass down traits like color, shape, or size to their young.

No state assessments at this grade
Students take their next one in Grade 4.
NAEP (National Assessment of Educational Progress)
Federally administered sample-based assessment in reading, mathematics, science, writing, and other subjects. NAEP results inform state-by-state comparisons rather than individual student or school accountability.
- When given:
- biennial in winter
- Frequency:
- every two years
Common Questions
What does second grade science actually cover?
Students explore four big areas: properties of matter, how forces make things move, Earth and weather, and living things and their habitats. They also learn how to ask questions, measure carefully, and explain what they found out.
How can families support science learning at home?
Cook together, watch the weather, sort recycling by material, or look at the moon a few nights in a row. Ask students what they notice and what they think will happen next. A short walk and a few good questions go a long way.
Do students need to memorize a lot of vocabulary?
Some terms matter, like solid, liquid, gas, force, habitat, and weather. But the goal is using the words to describe real things, not reciting definitions. If students can point to an example and explain it in their own words, they understand it.
How should the year be sequenced across the four content areas?
Many teachers start with matter and physical properties because the hands-on sorting and measuring builds investigation habits. Force and motion fits well next, then Earth systems and weather, then living things in spring when outdoor observation is easiest.
Which topics usually need the most reteaching?
States of matter often get confused when temperature changes are involved, and students mix up weather with climate. Forces are tricky too, since students focus on the moving object and forget the push or pull acting on it. Plan extra time and repeated examples for these.
What does a good science investigation look like at this age?
Students ask a testable question, predict what will happen, change one thing, measure with rulers or thermometers, and record results in a simple chart. Then they explain what the data shows. The thinking matters more than a polished write-up.
My child says science is just reading. Is that normal?
It should not be. Second graders learn best by doing: pouring water, rolling balls down ramps, planting seeds, tracking the weather. If reading is the main activity, ask the teacher about hands-on work or try simple experiments at home.
How will I know students are ready for third grade science?
By spring, students should describe physical properties of matter, explain how forces change motion, identify parts of Earth's systems, and tell how plants and animals survive in their habitats. They should also plan a simple investigation and record data in a chart.
