Circle the Gases

Start with something students can look at or think about: a photo, a short video, a jar on the windowsill, or a question like "what do you already know about solids, liquids and gases?" Then let them work through the first item together as a class, then finish the rest independently or with a partner, keeping a word bank or anchor chart in view so the vocabulary stays available. When you review, ask students how they knew, and let them point to the part of the diagram or reading that told them. These solids, liquids and gases worksheets work well as a lead in before an investigation, as a way to capture what students noticed afterward, or as review before an assessment.

Read clues and circle every picture that shows a gas, such as a balloon, steam or bubbles. A gas has no shape of its own. Most gases are hard to see. The directions on the page read: Read the box. Then, read the clue under each picture. Then, circle every picture that has a gas in it. The answer key shows every answer.

Yes, both. We made it for 1st Grade material properties, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with solids, liquids and gases. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

First graders learn that matter exists in three states and that each state behaves differently: solids have a fixed shape, liquids flow and take the shape of their container, and gases spread out to fill their container. They identify familiar examples of each state and explore simple examples of state changes, like ice melting to water.

The three states of matter are typically introduced in Grade 1 during a physical science or matter unit. Teachers often use water in its three forms, ice, liquid water, and steam (carefully), as a central example.

Cook or bake together and point out examples of all three states: the solid butter, the liquid oil, the steam rising from a pot. Ask your child to classify what they see and explain their reasoning. Watching ice melt in a glass at the table is also a simple, engaging demonstration of a state change.

6 printable worksheets, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.

These are written for 1st Grade students, roughly ages 6-7. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.

Yes. Each one shows the NGSS code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.
