Physical Science
Matter
Properties of Matter - Characteristics of a material that helps to identify or classify matter.
States of Matter - The forms matter can take, such as liquid, solid, or gas; also known as phases of matter.
Atoms - The smallest particle into which an element can be divided and still maintain the properties of that element. Ex. gold
Elements, Molecules, and Compounds - An element is considered the simplest form of matter. Molecules - Are formed when two or more atoms combine. Compound is matter made of two or more elements; The elements in a compound are chemically bonded, cannot be separated by physical means, and a compound has properties that are different from the elements that it is made of.
Periodic Table - Made up of horizontal rows and vertical columns of boxes. Each box contains specific information about a single element.
Chemical Formulas, Reactions, and Equations - A chemical formula is a shorthand way of describing a chemical compound. A chemical reaction takes place when one or more substances change to form one or more new substances. A chemical equation is a way of describing a chemical reaction using chemical formulas,
Mixtures, Solutions, and Suspensions - A mixture is a combination of two or more substances that have not combined chemically. A solution is a mixture that looks like a single substance and has the same properties throughout. Suspension is the kind of mixture, in which the components are dispersed but large enough to see and settle out.
Energy
Forms of Energy - There are many different forms of energy. They are mechanical, kinetic energy, potential energy, thermal energy, light energy, sound energy, electrical energy, chemical energy, nuclear energy.
Thermal Energy - Is the total amount of kinetic energy contained in all the particles of a substance
Waves - A wave is an oscillation that travels from one place to another with a certain velocity.
Light - this a type of energy produced by the vibration of electrically charged particles.
Sound - is produced when an object vibrates.
Electricity and Magnetism - Electricity is the interaction of electric charges. Magnetism can create electricity and electricity can produce magnetism. For this reason, they are closely related. Both are caused by negative and positive charges in matter.
Forces and Motion
Forces in Nature - A force is a push or a pull on an object. Objects exert forces on each other.
Balanced and Unbalanced Forces - Balanced forces produce no change in the motion of an object. Meaning that an object that is not moving will stay motionless, while an object that is moving will maintain its speed and direction. Unbalanced forces produce a change in the motion of an object.
Newton's Laws of Motion - Three laws, developed by Isaac Newton, that explain the motions of objects.
Work - When force is applied to an object and the object moves a distance.
Simple Machines - This is a device that makes work easier. Simple machines transfer force. Most simple machines make work easier by allowing you to use less force to move an object.
Forces in Fluids - A fluid is any material, either liquid or gas, that can flow. All fluids exert pressure as their molecules move around and bump into the surfaces of other matter. Pressure is the amount of force exerted by these molecules on a given area.
Physical Science Equations - These are mathematical equations that describe relationships among various physical quantities and phenomena in the natural world
