| Question | Answer |
| state the question or problem | first step of Scientific Method; the purpose of the experiment |
| research | using computers, books, and interviews to find out information about the topic before making a hypothesis |
| hypothesis | an educated guess about the outcome of an experiment; must be testable |
| Experiment | testing the hypothesis |
| Independent Variable | what is changed on purpose at the beginning of the experiment; manipulated variable |
| Dependent Variable | what is measured in the end; responding variable |
| constants | things that remain the same throughout the experiment; not changing |
| control | the normal or plain way of doing something that is used as a comparison group |
| procedures | directions for completing an experiment |
| data | information collected during an experiment |
| record and analyze data | step that involves creating a graph |
| conclusion | the last step; a statement as to whether or not the hypothesis is supported by the data or not |
| repeated trials | the number of times the experiment is performed; each trial should be done the exact same way |
| qualitative observations | not measurable such as color, texture, smell, taste |
| quantitative observations | can be measured to provide a number such as length, weight, temperature, time |
| length | distance between two points, includes height |
| mass | amount of matter in the object |
| weight | pull of gravity on the mass of an object |
| volume | amount of space an object occupies |
| density | amount of matter in a certain space (mass/volume) |
| balance | tool used to measure mass in grams |
| graduated cylinder | tool used to measure liquid volume in mL |
| water displacement | using a change in water level to determine the volume of an object |
| meter | basic unit of length in the metric system (SI) |
| liter | basic unit of volume in the metric system (SI) |
| gram | basic unit of mass in the metric system (SI) |
| Theory | a well- thought explanation of observations in nature |
| Law | describes what will happen in a situation often demonstrated by a mathematical equation |
