The science of the materials that make up the universe-what they are made of, how they interact, and how they change.
Everything that makes up the universe.
A form of matter that has a definite shape, size, and weight.
A form of matter that does not have a definite shape but has a definite weight and size. A liquid conforms to the shape of its container.
A form of matter that has no definite shape, weight, or size. The volume (size) of a gas is related to its temperature and the pressure being placed on it by its environment.
A form of matter that has many similarities to a gas. Plasma is found in conditions of extreme hear, such as the sun. Many of the properties of plasma are still something of a mystery.
The smallest form of matter (which cannot be cut into different pieces). Atoms are mane up of a number of smaller particles, the most important of which are protons, neutrons, and electrons.
A specific form of matter composed of only one type of atom. Elements cannot be divided into different types of matter. Elements are classified by the number of protons in an atom of that element.
Two or more elements combined chemically. The compound has different chemical properties than those of its individual elements, and it can only be separated by chemical means.
Two or more elements that are combined physically rather than chemically.
Lesson 1 Summary
Atoms make up elements...which make up compounds or mixtures...all of which are matter
