About this resource
Description
This states of things states of matter activity helps young scientists sort everyday things into the three states of matter: solid, liquid, and gas. A solid keeps its own shape, a liquid flows and takes the shape of its cup, and a gas spreads out to fill the space around it. Sorting real pictures by these rules builds a strong first understanding of matter.
How to Use This Activity
Print the 3 heading cards and the 12 picture cards, then cut them apart on the dashed lines. Lay the Solid, Liquid, and Gas heading cards in a row. Children pick a picture card, say its name, and ask: does it keep its shape, does it flow, or does it float up and spread out? Then they place the card under the right heading and write the card number on the Sorting Chart. This kindergarten matter activity also works well for first and second graders in a science center, with a partner, or in a small group.
What’s Included
- A colorful cover and a How to Use page with simple steps
- 3 heading cards: Solid, Liquid, and Gas
- 12 picture cards, from a rock and an ice cube to honey, paint, steam, and smoke
- A Sorting Chart
- A Kindergarten practice worksheet: circle the liquids
- An answer key for the card sort and the practice page
Why This Activity Helps Kids
First, hands-on sorting turns a big science idea into something children can see and touch. Second, saying why each item belongs builds science vocabulary and reasoning. Third, the practice page checks that children can spot a liquid on their own, which prepares them for second grade matter standards.
Ideas for Teachers and Parents
Use the states of things states of matter activity before a melting ice cube experiment, and talk about how ice changes from a solid to a liquid. Go on a home or classroom hunt for one solid, one liquid, and one gas, or have children draw a new picture card and sort it.
