Physical and Chemical Properties of Matter

In a dark room, how could you identify your parents? In a crowd, how could you identify your parents? Ask, what am I trying to get at? The more of these properties you have, the better you can identify the person. During an police investigation/line up, how could you identify the criminal?

Including people, all substances have properties! Example: People can be identified by their … Face (shape, expressions) Voice Height Finger prints Eye color Hair color Teeth DNA

Physical Properties Physical properties are used to identify, describe and classify matter. Characteristic of a substance that can be observed (using your senses) or measured without changing the substance into something else. Hardness Texture Color Odor Taste Temperature

More Examples of Physical Properties Luster Smell Size shape freezing point boiling point melting point attraction or repulsion to magnets Viscosity Density

Activity: Physical Properties Turn to your neighbor and explain physical properties using an object in the classroom. Pair share the prompt. Whole group answer then complete the activity. Have students complete the Activity: Physical Properties Activity: Physical Properties

Creating a new chemical product Chemical Properties Chemical properties are characteristics involved when a substance interacts with another substance to change its chemical make-up. Flammability Rusting Creating gas bubbles Creating a new chemical product Reactivity with water pH

More Examples of chemical Properties Flammability (the ability to catch on fire) Toxicity (the ability to be poisonous) Oxidation (the ability to react with oxygen, which causes apple slices to turn brown and iron to rust) Radioactivity (spontaneously emitting energy in the form of particles or waves by the disintegration of their atomic nuclei) Sensitivity to light (which causes newspaper to turn yellow). Being acidic or basic is another kind of chemical property.

Can you figure out the difference? Card sort – physical and chemical properties Check your answers with a teacher.

Turn to your neighbor and describe the differences between physical and chemical properties.
