Properties/Changes in Matter

SOLs: PS. 2

Foldable 1.  Use one sheet of drawing paper. 2.  Begin as if you were going to make a

hamburger fold but instead of creasing the paper, pinch it to show the midpoint.

3.  Fold the outer edges of the paper to meet at the pinch/mid-point to make it look like window shutters.

4.  Then fold in half like a hamburger and crease well.

5.  Open the project and cut along the two inside valley fold.

Physical Properties •  Characteristics that can be observed

without changing the substance •  You use your senses to measure or tell it •  Examples:

• Color, size, shape, texture, odor, taste, weight, luster (shiny), melting pt., boiling pt., freezing pt., density, solubility

Chemical Properties •  Characteristics that tell you how

something reacts •  Examples:

• Flammability • Sensitivity to light • Ability to rust

Physical Change •  A change in a substance’s size, shape, or

phase of matter •  Nothing new is created * Can go back •  Examples:

• Ice cream melting • Tearing paper • Water boiling into steam • Rain evaporating

Chemical Changes

•  Occurs when one substance changes into a new substance * Can’t go back •  Examples:

• Burning paper • Something decomposing/ rotting • Iron rusting
