| analysis | the process of studying results and data to find patterns |
| balance | a tool used for measuring mass (The units of measure for mass include grams and kilograms.) |
| conclusion | an opinion or judgment made after some thought and based on evidence |
| constant | all the factors and materials that remain the same during an experiment |
| data | information collected during an experiment |
| elapsed time | the amount of time that has passed from the beginning to the end of an event (measured using seconds, minutes, hours) |
| experiment | a fair test driven by a hypothesis |
| graduated cylinder | a tool used for measuring volume (The units of measure for volume include milliliters and liters.) |
| hypothesis | a prediction about the relationship between variables |
| inference | a conclusion based on evidence about events that have already occurred |
| length | the linear distance between two points (The units of measure for length include millimeters, centimeters, meters and kilometers.) |
| manipulated (independent) variable | he one factor in an experiment that is altered by the experimenter |
| mass | the amount of matter in an object (The basic unit of mass is the gram.) |
| metric ruler or meter stick | a tool used for measuring length (The units of measure for length include millimeters, centimeters, meters) |
| observation | the use of senses to collect information about the environment |
| prediction | a forecast about what may happen in some future situation |
| repeated trials | doing an experiment multiple times to avoid experimental error |
| responding (dependent) variable | the factor in an experiment that changes as a result of the manipulated variable |
| temperature | the amount of heat given off by an object (Temperature is measured in degrees Celsius.) |
| thermometer | a tool used for measuring temperature (The units of measure for temperature is Celsius.) |
| unusual results | inconsistent data that suggests an experimental error has occurred |
| volume | the amount of space taken up by an object (The basic unit of volume is the liter.) |
