Anything that has volume (takes up space) and mass Matter is... Anything that has volume (takes up space) and mass

Volume is The amount of space taken up by an object Units are: Liquid – mL Solid – cubic cm Gas – depends on the volume of the container

The amount of matter in a given substance Mass is The amount of matter in a given substance

Units: kg, g, mg Units: N (newtons) Measure of matter Measure of gravitational force measurements Measured with a balance Mass Weight Measured with a spring scale Used in science Always Constant no matter where the object is in the universe Varies depending on where object is in space

What is a property? A property is a characteristic (trait) or a special capability of an object Two types we will learn about in science: physical properties and chemical properties

What is an atom? The smallest particle into which an element can be divided and still retain all of the properties of that element Composed of: Protons: positively charged particles of the nucleus Neutrons: particles of the nucleus that have no charge Electrons: negatively charged particles found in all atoms, in the electron cloud

What are the building blocks of life? ATOMS

Physical forms in which a substance can exist States of Matter Physical forms in which a substance can exist

Four States of Matter Gas Solids Matter changes both shape and volume Plasma Does not have definite shape or volume and whose particles have broken apart. Solids Matter has a definite shape and volume Liquids Matter takes the shape of its container but has a definite volume
