Set up your note paper so that you have the Questions column on the left, the summary section on the bottom and the Essential Question. Name, Date and Period goes in the top right corner.

Chemical and physical properties of Matter (THIS GOES IN THE TOPIC SECTION OF NOTES)

Put this in the Essential Question box I can list the properties of a substance and classify them as physical properties or chemical properties.

What is Matter? _______is anything that has mass and takes up space Matter is composed of___________ which are pure substances made of only one kind of atom. ________are the building blocks of matter. Protons (+ charge) and Neutrons (no charge) are in the nucleus. Electrons (neg. charge) circle the nucleus __________and ___________are formed by 2 or more atoms combining in specific shapes Every element/compound is unique in some way from all others. Matter elements Atoms Moleculescompounds

Matter has 3 forms. Solid, Liquid, Gas

How can you describe matter if you don’t know what it is?

You try it!

We call these Properties It doesn’t matter what your object was, everyone used similar descriptions. What were some of the properties you listed about your object? Size, Weight & Mass, Shape, Odor, Sound, etc. After opening your bag, you were able to list even more properties such as color, texture, etc.

Physical Properties Physical properties can be observed or measured without changing the identity of the matter. They are determined by the use of the They are a of an object. Five senses description

Examples of Physical Properties Color Smell Taste Hardness State of Matter (solid, liquid or gas) Boiling, Freezing, or Melting Point

Examples of Physical Properties Density Mass Volume Conductivity - The ability of a substance to allow the flow of energy or electricity. As you read the words that you do not know the definitions, please make sure you list the words as well as the definitions and examples

Physical vs. Chemical Physical properties: observe without changing the identity of the substance Chemical properties: observe only when the identity changes How do you know if it is chemical or physical? If it CHanges, it’s CHemical Combustion of Mg strip

Chemical Properties ► Are determined by a substance’s ability to ► _______with other substances. react

Chemical properties A common chemical property is reactivity. Reactive to oxygen Reactive to air Reactive to water … Reactive to acid Notice that chemical properties aren ’ t EASY to observe, unlike physical properties.

Examples of Chemical Properties The ability to react with, _______, _________, __________ The ability to react with The ability to catch fire () air rusttarnish corroderot Water or acids flammability

We can group objects by their properties. How can we group these objects?

1.Did you sort them by color? One property is color. Color Red Green Yellow

Size Large objects Small objects 2. Did you sort them by size? A second property is size.

Circles Squares Triangles 3. Did you sort them by shape? A third property is shape. Shape
