Sorting and testing materials
Students look closely at everyday stuff like fabric, wood, metal, and plastic. They sort items by how they feel and look, then test which ones work best for a job, like keeping something dry or holding weight.
What does a student learn in
This is the year science becomes hands-on testing and careful observation. Students sort everyday materials by what they can see and feel, then check which ones work best for a job like keeping something warm or holding water. They plan small experiments to see what plants need and notice how wind and water reshape the ground over time. By spring, they can explain with examples why melting ice can refreeze but a burned piece of toast cannot go back.

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
Building, melting, and freezing
Students take small pieces apart and put them back together to make something new. They also watch what happens when things heat up or cool down, and notice that melted ice can refreeze but a burned piece of toast cannot go back.
- 3
Plants, animals, and habitats
Students grow plants to see what happens with and without sunlight or water. They also study how bees, birds, and other animals move pollen and seeds around, and compare the kinds of life found in a forest, a pond, or a backyard.
- 4
Land, water, and Earth changes
Students map the hills, rivers, and lakes in an area and learn where water shows up as ice or liquid. They look at how some Earth changes happen fast, like a landslide, and others happen slowly, like a canyon wearing down.
- 5
Protecting the land
Students compare ways people try to stop wind and water from washing away soil or reshaping a shoreline. They weigh different solutions, like planting grass or building a barrier, and decide which one holds up best.

2-PS1-2Students test materials like wood, plastic, and fabric to find out which one works best for a specific job. A wooden block floats; a metal one sinks. The right material depends on what the object needs to do.

2-PS1-3Students take apart a small object and use the same pieces to build something new. This shows that the same materials can be rearranged without any pieces being lost or added.

2-PS1-4Heating and cooling can change materials, but not always in the same way. Students learn which changes can be undone, like melting ice, and which cannot, like cooking an egg.

Common Questions
What science will students learn this year?
Students study four big topics: what stuff is made of and how it changes, how plants and animals live together, how Earth changes, and where land and water are found. A lot of the work happens through hands-on investigations and simple models.
How can I help with science at home?
Sort laundry, coins, or rocks by what students notice: color, size, hardness, or how they feel. Talk about why some things melt back when they cool and some do not, like ice versus a burned piece of toast. Short kitchen and backyard moments count.
How should I sequence the year?
Many teachers start with properties of materials in fall because the investigations are short and build observation habits. Plants and habitats fit spring when seeds and weather cooperate. Earth changes and water can run any time and pair well with read-alouds.
My child is not a strong reader yet. Can they still do science?
Yes. Most of the work is watching, sorting, drawing, and talking. Help at home by asking what they noticed and what they think will happen next. Writing one sentence about what they saw is plenty.
What does mastery look like by the end of the year?
Students can plan a simple test, record what happened, and use those notes as evidence for a claim. They can describe land and water in an area with a model, and explain that some changes from heating or cooling can be undone and some cannot.
Which ideas usually need the most reteaching?
Reversible versus irreversible changes trip students up, especially telling melting apart from burning or rusting. The idea that a model stands for something real also takes practice. Build in extra time for both, with several short examples rather than one long lesson.
What is a simple home project that fits this year?
Plant the same seeds in three cups: one in sun with water, one in a dark closet with water, one in sun with no water. Check daily for a week or two and talk about what the plants needed. This matches the work students do in class.
How do I know my child is ready for next year?
They should be able to describe something they tested, what they saw, and what it tells them. They should also sort objects by properties and use a drawing or map to show real places. If those feel comfortable, they are in good shape.
