Ever wondered what makes up everything around you? From the air you breathe to the chair you sit on, the food you eat, and the stars twinkling in the night sky? We’re talking about matter – the stuff that occupies space and has mass. It’s everywhere, and understanding it is crucial to grasping the vast expanse of the universe around us. But who better to guide us on this journey than the one and only, Bill Nye the Science Guy! With his infectious enthusiasm and knack for making science fun and relatable, Bill Nye simplifies even the most complex concepts, making the world of matter both fascinating and accessible.

Joining Bill Nye on this exploration of matter allows us to unravel the mysteries of our physical world. We’ll delve into the building blocks of matter, its different states and properties, and how it transforms under various conditions. Together, we’ll unravel the secrets of the universe, one atom at a time, while having a blast along the way.
What is Matter?
Imagine a universe devoid of any substance. No planets, no stars, no air, no life – just emptiness. Hard to comprehend, isn’t it? This is why we need matter. It’s the stuff that everything is made of, and it defines our existence. But what is matter, exactly?
Matter is anything that takes up space and has mass. Think of it this way: If you can touch it, see it, or feel it, it’s matter. A rock, a tree, a cloud, even the air we breathe – they all occupy space and have mass.
States of Matter
You’ve likely experienced matter in its three most common states: solid, liquid, and gas. Bill Nye calls these the “Three States of Matter.” Imagine a block of ice – that’s solid. Now let it melt into water, that’s liquid. If you heat the water, it turns into steam, a gas. But matter doesn’t stop there!
Solid
Solids are like organized troops, their molecules packed tightly together in a fixed structure. They maintain their shape and volume, resisting changes in form. Think of a rock, a brick, or a piece of metal. Their molecules are practically holding hands, vibrated in place.

Liquid
Liquids are a bit more free-flowing. Their molecules are closer than in gases but have weaker bonds. They can flow and take the shape of their container, but they retain their volume. Think of water, juice, and oil. They’re like social butterflies, able to move around within their environment.
Gas
Gases have molecules that are far apart and move freely. They can expand to fill any container and take its shape. Air is a prime example of a gas, as are the steam coming from boiling water and the carbon dioxide we exhale. Gases are like independent spirits, roaming freely wherever they please.
Plasma
Beyond these three, there’s a fourth state of matter – plasma. It’s a super-heated gas where electrons are stripped from their atoms, creating a mixture of charged particles. You might be surprised to know that plasma is the most abundant state of matter in the universe! Think of lightning, the Northern Lights, or the sun – they’re all examples of plasma. Bill Nye often calls it the “fourth state of matter,” emphasizing its importance in understanding the cosmos.
The Building Blocks of Matter: Atoms
Everything we see is made of tiny particles called atoms. Bill Nye often uses the analogy of an atom being the “Lego block” of the universe. Each atom is like a miniature solar system, with a tiny, dense nucleus at its center and electrons swirling around it.
The Atom
The nucleus, like the sun in our solar system, contains protons and neutrons. Protons have a positive charge, while neutrons carry no charge. Whizzing around the nucleus are electrons, tiny particles with a negative charge, creating a sort of cloud of energy around the nucleus. Atoms, though incredibly small, define matter’s nature and behaviour.
Elements
You could say atoms are the building blocks, but elements are the blueprints. Each element is a unique type of atom. There are over 100 known elements, each distinguished by the number of protons in its nucleus. For example, hydrogen has one proton, helium has two, and carbon has six. These elements combine in countless ways, forming the multitude of substances we see around us.
Compounds and Mixtures
When different elements combine, they create compounds. Water, for example, is a compound of hydrogen and oxygen (H2O). Compounds have different properties than the original elements that make them up. But when different substances are combined without altering their chemical composition, they form mixtures. Saltwater, for instance, is a mixture of salt and water. Each substance retains its distinct properties.
Properties of Matter
Matter has various properties that help us understand its behaviour and differentiate it from other forms of matter. These properties can be classified as physical or chemical, depending on whether they alter the substance’s chemical composition.
Physical Properties
These properties can be observed and measured without changing the substance’s chemical makeup. Examples include colour, texture, density, melting point, boiling point, and magnetism. They are like a matter’s fingerprint, allowing us to identify and differentiate it from others.
Chemical Properties
Chemical properties describe a substance’s ability to undergo a chemical change. This change alters the substance’s chemical composition, often resulting in the formation of new substances with different properties. Examples include flammability, reactivity, and oxidation.
Changes in Matter
Matter doesn’t remain static. It undergoes changes, some subtle and others drastic. These changes can be grouped into physical and chemical changes.
Physical Changes
These changes alter a substance’s physical properties without changing its chemical composition. Think of ice melting into water or water freezing into ice. They are the same substance (H2O) but in different states. Another example is crushing a can – its shape changes, but its chemical composition remains the same.
Chemical Changes
Chemical changes rearrange the atoms within a substance, resulting in the formation of new substances with different properties. Burning wood, for example, results in the formation of ash, carbon dioxide, and other byproducts. The wood has undergone a chemical change, and its original composition has been altered.
Matter in the Universe
Matter is not confined to our planet. It’s everywhere in the universe. From the rocky planets and asteroids to the swirling clouds of gas that form nebulae, matter is the foundation of the cosmos. Studying the composition and behaviour of matter in space helps astronomers and physicists understand the origins and evolution of the universe.
