Solids, Liquids, and Gases by Ginger Garrett1. Awards: n/a
2. Appropriate Grade Level: Kindergarten- 4th grade
3. Original Summary: This informational text introduces the different forms of matter: solids, liquids, and gases. It places emphasis on the fact that everything is made up of matter. It shares that some things can change form by heating or cooling.
4. Original Review: There are colorful photos and simple text that can allow students to make educated assumptions and read on their own. There is an index and word list, which I believe is helpful. The text is repetitive.
5. 2-3 in class uses: This book can be used to form questions about their life, the environment, and different organisms.
Solids, liquids, and gases
Water is the only common substance that is naturally found as a solid, liquid or gas. Solids, liquids and gases are known as states of matter. Before we look at why things are called solids, liquids or gases, we need to know more about matter. Matter can be a confusing word because it has several meanings. Scientists have a different meaning for matter — matter is anything that occupies space and has mass.
Matter is all around us. Matter is the air you are breathing. Matter is the computer you are reading from now. Matter is the stuff you touch and see. And it is more. Matter is defined as anything that has mass and takes up space. Matter is found in 3 major states; solid, liquid and gas.
Whether you are looking at elements and matter in the laboratory or in nature, there are three different types of matter that you will be able to observe. These three are known as solids, liquids, and gases. Take a look around you right now. Odds are, you can observe at least one of these three states of matter. Atoms and molecules do not change. They always have the same numbers of protons and electrons. What can change, however, is how they behave.
Matter is everything around us
Solid Basics What is one physical characteristic of a solid? Solids can be hard like a rock, soft like fur, a big rock like an asteroid, or small rocks like grains of sand. The key is that solids hold their shape and they don't flow like a liquid. A rock will always look like a rock unless something happens to it. The same goes for a diamond. Solids can hold their shape because their molecules are tightly packed together. You might ask, "Is baby power a solid?
Solids are one of the three states of matter and, unlike liquids or gases, they have a definite shape that is not easy to change. Most solids are made up of tiny crystals. Solids behave as they do because of the way their particles are arranged. The particles of a solid are linked by strong forces, which pull the particles tightly together. So, although the particles can vibrate, they cannot move about easily. This arrangement explains why solids usually keep their shape and feel firm. Some solids can be hammered or squashed into many different shapes without breaking.
