What is Matter? Objective What are we doing? Today we will describe matter and analyze it’s parts. How will we do it? By comparing and contrasting physical and chemical properties of matter and sorting examples of both. Activity

Vocabulary anything that has mass and takes up space. Term Definition Picture Matter  anything that has mass and takes up space.   Chemistry study of the properties and changes of matter. Substance a single kind of matter that has the same properties. Physical Change a change in the size or state of matter. Chemical Change when the molecules of matter change.

There are two kinds of properties that every form of matter has: Physical Properties State Color Size Hardness Odor Solubility Density Melting Point Boiling Point Chemical Properties Ability to Rust Flammability (Fire) Combustibility (Explosive) Reactivity with vinegar Decomposition rate Chopped Wood

Chopped Wood PHYSICAL CHEMICAL A characteristic of a substance that can be observed without changing it into another substance. A characteristic of a substance that describes its ability to change into different substances. A characteristic of a substance that can be observed without changing it into another substance.
