| Manipulated variables are also sometimes called what? | Independent Variables. |
| The factor that may change in response to the manipulated variable is called what? | The Responding Variables. |
| What is the Responding Variable? | The factor that may change in response to the manipulated variable. |
| Responding variables are also sometimes called What? | Dependent Variables. |

| Tables and graphs are tools that scientists use to do what? | Organize and present information. |
| Tables allow what? | Allow a lot of information to be presented in a small space by organizing data efficiently. |

| Circle graphs are best used to show what? | To show how a whole is divided into parts (or percentages of a whole). |
| Bar graphs are best used for what? | They are used for counting and to show how a number of objects or events compare in relationship to a single property. |
| Line graphs are best used to show what? | They are used to show a relationship between two measured quantities, usually as a trend over time. |
| What is the x-axis & y axis in a experiment? | The x-axis is the horizontal axis & is where the independent variable is placed. The y-axis is the vertical axis & is where the dependent variable is placed. |
