What does a student learn in ?

This is the year science becomes hands-on investigation. Students ask questions about how things move, test what happens when materials heat up or cool down, and track weather across the seasons. They look at where water shows up on Earth, study how plants spread their seeds, and learn how Minnesota American Indian Tribes choose the right material for a job. By spring, students can run a simple experiment, record what they see, and explain their thinking with the evidence they collected.

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. 1

    Asking questions about motion

    Students start the year as careful observers. They watch how things roll, slide, and stop, then ask questions they can actually test by pushing, pulling, or changing the setup.

  2. 2

    Heating, cooling, and materials

    Students test what happens when materials get warmer or colder. They notice which changes can be undone, like melting an ice cube, and which cannot, like baking bread.

  3. 3

    Materials with a purpose

    Students look at why certain materials get used for certain jobs. They learn how Minnesota American Indian Tribes and other cultures choose materials that fit the work, from clothing to shelter to tools.

  4. 4

    Weather and water on Earth

    Students chart what weather to expect across the seasons and find where water shows up around the world. They also compare designs meant to protect homes from storms, wind, and flooding.

  5. 5

    Plants, animals, and habitats

    Students close the year studying living things. They build a device that spreads seeds the way nature does and use evidence to explain why some animals thrive in a habitat while others struggle.

Mastery Learning Standards
The required skills a student should display by the end of Grade 2.
Physical Science
  • Asking questions and defining problems

    2P.1.1

    Students ask questions about physical science topics and figure out what problem needs solving before starting an investigation.

  • Students will be able to ask questions about aspects of the phenomena they…

    2P.1.1.1

    Students ask questions about things they notice, experiments they run, and ideas they read about. Wondering "why does that happen?" or "what if we tried this?" is where science starts.

  • Ask questions about an object's motion based on observation that can be…

    2P.1.1.1.1

    Students watch something move, then come up with a question about it that a simple test or experiment could answer. Think: "Why does the ball roll faster on the smooth floor than the carpet?"

  • Planning and carrying out investigations

    2P.1.2

    Students plan a simple test, gather what they need, and record what happens. The focus is on asking a question first, then finding out the answer by trying something real.

  • Students will be able to design and conduct investigations in the classroom…

    2P.1.2.1

    Students plan a simple test to answer a question they have about something they noticed, then gather and record results that back up what they think is happening.

    2P.1.2.1.1

    Students plan a simple test to see what happens when they heat or cool everyday materials like water, butter, or clay. They watch and describe how the material looks, feels, or changes shape as the temperature goes up or down.

  • Using mathematics and computational thinking

    2P.2.2

    Students use counting, measuring, and simple math to describe what they observe in science. They might measure how far an object moves or count how many times something happens.

    2P.2.2.1

    Second graders use numbers and simple patterns to describe what they observe, like measuring how far a ball rolls or comparing weights. They also follow step-by-step rules to figure out how things in nature or everyday objects work.

  • Identify and predict quantitative patterns of the effects of balanced and…

    2P.2.2.1.1

    Students look at how pushes and pulls affect a moving object, then predict what will happen next based on the numbers they observe. A balanced push keeps an object still; an unbalanced one gets it moving or changes its direction.

  • Develop a simple diagram or physical model to illustrate how some changes…

    2P.3.1.1.1

    Students draw or build a model showing what happens when something heats up or cools down. Some changes, like ice melting, can be undone. Others, like a cooked egg, cannot.

  • Engineer a device that mimics the structures and functions of plants or animals…

    2L.3.2.2.1

    Students design and build something that works the way a plant or animal does to scatter seeds. They study how nature moves seeds (by wind, water, or fur) and use that idea to create their own device.

  • Engaging in argument from evidence

    2L.4.1

    Students look at two different explanations about living things and decide which one has better evidence to back it up.

  • Students will be able to engage in argument from evidence for the explanations…

Common Questions
  • What science will students explore this year?

    Students study how things move, how heating and cooling change materials, weather and water on Earth, and how plants and animals survive in different habitats. They also start designing simple solutions, like a device that helps a seed travel.

  • How can families practice science at home?

    Talk about the weather each morning and keep a simple chart for a week. Melt an ice cube and refreeze it, then toast bread and try to un-toast it. Ask what changed back and what did not. Five minutes of noticing counts.

  • What should a child be able to do by the end of the year?

    Students should ask a question about something they noticed, plan a small test, and share what they found with a drawing or chart. They should also explain why some changes from heat or cold can be undone and some cannot.

  • How do I sequence the year across the three strands?

    A common path is matter and motion in the fall, weather and water through winter, and habitats and seed dispersal in spring. Weave the science practices, like asking questions and building models, into every unit instead of teaching them on their own.

  • What usually needs the most reteaching?

    Two ideas stick the hardest: which changes from heating or cooling can be reversed, and the difference between balanced and unbalanced forces. Plan extra hands-on rounds with ice, clay, butter, and ramps, and ask students to predict before they test.

  • My child says science is just drawing pictures. Is that right?

    Drawings are models, and models are a real part of science at this age. A labeled picture of how a maple seed spins to the ground, or how ice melts into water, shows thinking. Ask what each label means and what the arrows show.

  • How should investigations look in a second grade classroom?

    Short, repeatable, and tied to one question. Students plan with a sentence frame, collect data in a simple table or tally, and share findings in pairs before the group. Keep materials familiar, such as ice, fabric, ramps, rain gauges, and seeds.

  • How is the contribution of Minnesota American Indian Tribes included?

    Students learn how Tribes and communities choose materials based on properties such as warmth, strength, or flexibility, like birch bark for containers or wool for cold weather. Use sources from Tribal Nations themselves when possible, and connect the choices to the science of materials.

  • How do I know a child is ready for third grade science?

    Look for a child who notices patterns in weather, motion, or living things and can describe them in a sentence or sketch. They should be able to plan a simple test, record what happens, and use that evidence when they explain their thinking.
