Thinking like a scientist
Students learn to ask questions, try small experiments, and share what they noticed. They practice using simple tools carefully and drawing or writing about what they saw.
What does a student learn in
This is the year science moves from noticing things to asking questions and testing them. Students learn to pose a question, plan a small investigation, and use tools like rulers, magnifiers, and thermometers to gather evidence. They study how living things depend on each other, how weather changes across seasons, and how objects move when pushed or pulled. By spring, they can describe what they observed and explain what it shows.

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
Sky, weather, and Earth
Students watch the sky and track weather day by day. They notice patterns in the sun, moon, and seasons, and look at how rain, wind, and temperature change over time.
- 3
Living things and habitats
Students look at plants, animals, and the places they live. They compare how different creatures get food, stay safe, and depend on each other in the same backyard or pond.
- 4
Matter, motion, and energy
Students explore how things feel, move, and change. They push and pull objects, watch ice melt, listen to sounds, and notice how light and heat travel.
- 5
Solving a real problem
Students pick a small problem and try to build or design a solution. They test an idea, see what works, and change it based on what they learned.

Scientific Inquiry, Practice, and Applications
Scientific Inquiry, Practice, and Applications
-
Asking Questions
Students pick a question about the natural world and design a simple test or observation to find the answer.
-
Designing Investigations
Students plan a simple experiment, choose the right tools for the job, and follow basic safety steps while they test their question.
-
Analyzing Evidence
Students look at what they observed or measured and use it to back up a conclusion. If a claim says ice melts faster in warm water, students point to the numbers or notes that show it.
-
Communicating Findings
Students share what they learned from a science activity by drawing pictures, writing sentences, or explaining it out loud to the class.
-
Engineering Design
Students follow a step-by-step design process to spot a problem, come up with a fix, and test whether it works. Think building a bridge out of craft sticks or designing a better rain shelter.

Earth and Space Science
Earth and Space Science
-
Earth's Place in the Universe
Students learn where Earth sits among the planets and describe patterns they can observe, like how the sun appears to rise and set or how the moon changes shape over the course of a month.
-
Earth's Systems
Students explore how the land, water, air, and living things on Earth work together and affect one another. A rainstorm filling a river, or roots holding soil in place, are the kinds of connections students look for.
-
Weather and Climate
Students look for patterns in daily weather, like how temperature or rain changes across seasons, and start to understand why some places are consistently hot, cold, wet, or dry.
-
Human Impact
Students look at how everyday human choices, like building roads or planting trees, change the land, water, and air around us.

Life Science
Life Science
-
Diversity and Interdependence
Students look closely at plants and animals to understand how living things in a place depend on each other. A forest, pond, or field works because each organism plays a role in keeping the others alive.
-
Cells, Heredity, and Evolution
Second graders observe how living things grow and change, and how traits like eye color or leaf shape get passed from parents to offspring. They also look at how animals and plants change over time to survive in their environment.
-
Human Body
Students look at how different parts of the body work and what each part does. They learn how parts like the heart, lungs, and bones work together to keep the body running.

Physical Science
Physical Science
-
Properties of Matter
Students sort, bend, mix, and observe materials to learn how matter can change shape, melt, or turn into something new.
-
Forces and Motion
Students push, pull, and move objects to see how forces change the way things go faster, slower, or in a different direction.
-
Energy
Students explore how energy shows up in different forms, like heat, light, and sound, and watch what happens when it moves from one object to another. Energy doesn't disappear; it just changes form or moves somewhere new.
-
Waves
Students explore how waves move energy from one place to another, like sound traveling through air or light bouncing off a surface. They look at wave properties and how people use waves to send information.

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, and writing. 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 science look like this year?
Students ask questions about the world and try to answer them by looking closely, testing, and measuring. They study weather, plants and animals, the sky, matter, motion, and energy. Most of the work happens through hands-on investigations, not reading from a textbook.
How can I help my child with science at home?
Notice things together and ask why. Watch the moon for a week, sort rocks from the yard, freeze and melt water, or roll toy cars down a ramp at different angles. Five minutes of wondering out loud counts as science at this age.
Does my child need to memorize a lot of science vocabulary?
No. The point is doing science, not reciting terms. Students should be able to describe what they saw and what they think it means in their own words. Fancy words can come later.
How should I sequence the year across so many topics?
Many teachers anchor each quarter in one big area: weather and sky in fall, living things in winter, matter and motion in spring, with engineering design woven through. Pick investigations that let the same inquiry skills come back again and again.
Which skills usually need the most reteaching?
Recording observations with enough detail, and telling the difference between what was observed and what was guessed. Measuring with a ruler or thermometer also takes more practice than people expect. Build short routines for these and revisit them all year.
What should my child do when an experiment does not work?
Treat it as information, not a failure. Ask what happened, what changed, and what to try next. Scientists at every level redo things, and getting comfortable with that now makes the rest of school science much easier.
How do I know my child is ready for next year?
Students should be able to ask a question, plan a simple way to test it, record what they notice, and explain their thinking out loud or on paper. They should also use basic tools like rulers, thermometers, and magnifiers without much help.
How much of the year should be hands-on versus reading?
Most of it should be hands-on or observation-based, with short reading and writing pieces tied to what students just did. Reading about a topic lands better after students have something real to connect it to.
What is the engineering design part about?
Students define a small problem, build something to solve it, test it, and improve it. Think paper bridges that hold pennies or shade structures for a toy. The goal is the cycle of try, test, and revise, not a perfect final product.
