| Question | Answer |
| Three states of Matter : | Solid; Liquid; Gas |
| What is the difference between a physical and chemical change? | A physical change doesn't change the substance of the material, a chemical change does. |
| What is matter? | Matter is what everything on Earth is made of. |
| What is matter measured in? | Matter is measured in mass using grams as unit of measurement. |
| What is volume? | Volume is the measurement of how much space an object takes up. |
| What is unit usually used to measure volume? | Centimeters Cubed |
| How do you find the volume? | Length x Width x Height |
| What is density? | Measurement that relates the mass of an object to the volume. |
| What is density usually measured in? | Grams per Cubic Cenitmeter |
| How do you find the density of an object? | Mass/Volume |
| What is weight? | Measurement of the pull of gravity. |
| What is the unit of measurement used to measure weight? | Kilograms, Pounds, Newtons . . . |
| What is gravity? | Force on Earth that keeps everything in our atmosphere. |
| What is an element? | Substance that cannot be chemically inter-converted or broken down into a simpler substance. |
| What is the smallest part of an element? | Atom |
| What is the smallest part of an atom? | Molecule |
| How do you read a graduated cylinder? | A graduated cylinder has little lines that are each worth a millimeter (a.k.a. cubic centimeter). The water curves a little in the tube so the bottom of the line is what is supposed to be read. |
| What is the curved water line inside a graduated cylinder called? | Meniscus |
| Why does mass remain the same and weight changes if you are on another planet? | The force of gravity changes on different planets, but an object does not shrink or grow on another planet. |
| What can be used to find the mass of an object? | A spring balance or a balances with masses can be used to find the mass of an object. |
