Inspiration for the week. “The elevator to success is out of order. You’ll have to use the stairs…one step at a time.”- Joe Girard Inspiration for the week. What do you think this means? _Hard work, perseverance, determination. Pair Share: I will give you a certain amount of time to talk about only the question asked. Today we will do this throughout the presentation. Sometimes I will look for share outs. Do not get off task. Dojo Points will be rewarded.

Physical & Chemical Properties Materials: Color Pencils Pencil Scissors Tape or Stapler

Review Matter= Anything that has mass and takes up space Mass= A measure of how much matter is in an object. Weight= A measure of the force of gravity on an object. Volume= The amount of space that matter occupies. Density= The measurement of how much mass of a substance is contained in a given volume Review

Physical Properties Top Left Box can be observed without changing the identity of the substance. Examples: Top Left Box melting point boiling point density Color Smell/odor Elastic Shape size viscosity conductivity malleability hardness Magnetism Density Volume Thing you can see about the object in front of you.

Examples of Physical Properties Viscosity of a substance is its resistance to flow. Examples: water = low viscosity honey = high viscosity Conductivity is a material’s ability to allow heat to flow. Examples: metal = high conductivity wood = poor conductivity

Examples of Physical Properties Malleability of a substance is its ability to be hammered into a thin sheet Melting and Boiling points are the temperatures at which a solid becomes a liquid and a liquid becomes a gas. Density of a substance is the ratio of its mass compared to its volume.

Physical Properties to separate mixtures Two common separation methods: Filtration – process that separates materials based on the size of their particles. Distillation – process that separates the substances in a solution based on their boiling points.

Physical Change It is a physical change if . . . A change in the appearance, without changing the composition of the material. It is a physical change if . . . Can be reversible, or irreversible Substance may seem different, but the way the atoms link up is the same. It dissolves. Or the substance changes phase. It changes shape or size Choral Response

Physical Change Does not form a new substance Bottom Left Box Draw and label each: Melting Ice Cream Streched Rubber Band Sliced fruit Bottom Left Box

Chemical Properties Chemical property is any ability to produce a change in the composition of matter. Examples of chemical properties . . . flammability reactivity Material’s ability to burn in the presence of oxygen. How readily a substance combines chemically with other substances.

Chemical Properties Top Right Box Describes matter on its ability to change into new matter with different properties. These can only be seen during a chemical change. Examples: Rust Flammability Reactions Explosion Top Right Box

Chemical Changes occur when a substance reacts and forms one or more new substances with new and different properties. Bottom Right Box A change in color. (Draw a cup with a spot of color) Production of a gas and bubble are formed. (Draw test tube with bubbles) You know a chemical change has occurred when . . . Solid material forms in a liquid=precipitate (Draw a cup with a solid square in the middle) The change is difficult to reverse (Draw a campfire)
