| Term | Definition |

| How is density used to identify a substance? | if you don't know what a substance is you can find the density and every substance has it's own density |
| What is the formula for density? | the formula for density is mass divided by volume |
| What is the density of water? | 1.0g/cm3 |
| What is the density of water? How can this fact help you arrive at other conclusions about density, mass, and volume? | if you know the density of one substance you can divide density by mass or volume |
| What substances would float/sink in water? | soap would sink, a wooden golf tee floats, a paper clip can float or sink |
| What happens to the mass and density of water when you add salt to make salt water? What would happen if you carefully poured water on top of salt water? Why? Relate your answer to the Rainbow in a Straw Lab | it makes it more dense, it would sit on top because it is less dense, |
| What is matter made of? | Matter is made up of mass |
| What are the three states of matter? How do they compare when it comes to definite shape and definite volume? | solid,liquid and gas. a solid has a defined volume and shape, a gas does not have a defined volume or shape, a liquid does not have a defined shape but it does have a defined liquid. |
| What's the difference between an irregular and regular solid? | an irregular solid you can't measure and a regular solid you can measure . |
| Describe the particle movement in each state of matter. | solid: the molecules are vibrating in place, a liquid they are moving more than a solid and can over come each others attraction and a gas they are all over the place |
| Name two unique characteristics of liquids. Describe these characteristics. | one is surface tension. surface tension is the amount of force it takes to break the surface. viscosity is another one. viscosity is the property of a liquid that resists to flow because of it's molecules |
| Using the term, viscosity, explain why honey flows more slowly than water. | it has a slower viscosity because the molecules are packed tighter together. |
