Properties of Matter

This is made of 2 or more ELEMENTS that stick together

H2O or Water is a COMPOUND

They are combinations of 2 or more different types of matter.

Sometimes you can take them apart, sometimes you can't

Example: Hamburger, trail mix

They are a SPECIAL kind of MIXTURE

They are made when you dissolve things into a LIQUID

You can't take it apart once you combine it

Just put things together (trail mix, cheeseburger)

Combine things chemically-when you combine things chemically, the matter "reacts". Like when you mix oxygen and fuel, you get a reaction called FIRE.

Inside each plastic lightstick there are chemicals and a glass tube

When you bend the lightstick, you break the glass tube and mix it with the chemicals-that makes it light up

Lightsticks do not give off heat

She was very interested in reducing pollution in water.

Thanks to her, Massachusetts was the first state to have rules that made sure EVERYONE had clean water.
