So it is made of plastic, wood, or rubber. For example, a screwdriver has to be strong and hard, so it has a steel tip. Properties decide how a material is used. What color is it? Is it see-through? Does it float? Does it burn easily? Does it feel warm or cold to touch? Does it conduct (carry) electricity? The Right Material Other properties include how strong, stretchy, or flexible (bendy) a material is. Air is a mixture of oxygen, nitrogen, and other gases.ĭifferent materials have different features and ways of behaving. Mixture: A material made of different substances mixed together. Matter: The stuff from which everything is made.Įlement: A material that is the same throughout, such as gold or silver.Ĭompound: A substance made of molecules, each of which is made up of two or more different types of atoms. Several words are used to describe matter and materials. Modern materials such as plastics and carbon fiber are used to make sports gear, like this snowboard and helmet. Atoms are the basic building blocks of matter and bind together to make elements.These axe heads and arrowheads were carved about 9,000 years ago, during the Stone Age. Matter can exist in three states, either as a solid, a liquid or a gas. Matter is made of single particles called atoms and is any substance that has either mass or volume. What makes up the building blocks of matter? Solids contain particles that are tightly packed, with very little space between particles.
Why is matter made up of particles? The arrangement of particles determines the state of matter. All matter is made up of tiny particles called atoms. Planet Earth is made of matter, and so are all the stars, planets, and moons in the universe. What makes up all the matter in the universe?
In a solid, the particles are very attracted to each other. Solids, liquids, and gases are made of tiny particles called atoms and molecules.
Matter on Earth is in the form of solid, liquid, or gas. What kind of matter is the Earth made of? Matter can exist in three states, either as a solid, a liquid or a gas…. What are the particles that make up matter?
