In Grade 1 science, you will learn about solids and liquids, the two kinds of matter kids see all day long. A solid, like a rock, a book, or a block, keeps its own shape and feels firm when you hold it. A liquid, like water, milk, or juice, flows and takes the shape of its cup or bowl. You will describe objects by their properties, such as color, size, weight, shape, smoothness, and temperature. You will also explore how water can change between solid ice, liquid water, and steamy gas when it gets very cold or very hot. Many Grade 1 learners think all tiny things float and all big things sink, but heavy pebbles sink while big logs float. Some kids also believe solids can never change shape, yet ice melts into water every day. Others mix up the words liquid and wet, but wet is just how liquids feel on skin. This topic builds on Kindergarten object observations and gets you ready for Grade 2, where you will add gas to your study of states of matter.

Common Mistakes to Watch For

  • Thinking all small or light-looking things float and all big things sink, when really heavy pebbles sink and large wooden logs float.
  • Believing solids can never change shape, when in fact ice melts into water and water freezes back into ice every day.
  • Mixing up the word liquid with the word wet, when wet just describes how a liquid feels on your skin.

Frequently Asked Questions

What is the difference between a solid and a liquid in Grade 1 words?

A solid keeps its own shape, like a rock or a block, and you can hold it. A liquid flows and takes the shape of its cup, like water or juice, and you usually pour it instead of holding it.

Is ice a solid or a liquid?

Ice is a solid. It is water that got so cold it froze and turned hard. When ice warms up, it melts and becomes liquid water again.

Why do some things sink and others float?

Objects that are heavy for their size sink, like rocks and metal coins. Objects that are light for their size, like leaves, wood, and rubber ducks, float on top of the water.

Can the same stuff be both a solid and a liquid?

Yes, water can. When it is very cold, water is solid ice. At room temperature it is liquid water. When it is heated a lot, it turns into steam, which is a gas you study more in Grade 2.

What properties do Grade 1 kids use to describe solids and liquids?

We describe objects by color, size, shape, weight, smoothness, roughness, and temperature. These properties help us tell one object from another and sort solids from liquids.

Are these worksheets really free?

Yes! All our worksheets are 100% free to download and print. There's no subscription, no hidden fees, and no registration required.
