| A | B |
|---|
| Independent variable | the one factor you change or test in an experiment the cause; also called the test variable or manipulated variable( usually on th ex-axis |
| Inference | An assumption or conclusion you can make about an observation Can be proven correct or incorrect with further investigation |
| Conclusion | The end of an experiment Tells whether the hypothesis is supported or not supported |
| Dependent variable | What you measure in an experiment to see if the change had an effect the outcome variable; the responding variable ( usually on the y-axis) |
| Observation | Data information that can be gathered through your senses facts only |
| Controlled experiment | An experiment in which only 1 variable is manipulated changed at the time |
| density | Measure comparison of how much mass is contained in a given volume; unit is g/cm3 |
| weight | Measurement of the pull of gravity can change depending on location |
| measure | To determine the dimensions quantity or capacity of an object |
| predict | To make a statement ahead of time of what you think will happen based on information or experience |
| classifying | Grouping items together that are alike in some way |
| scientific inquiry | All the ways scientific problems can be solved Diverse ways scientists study the natural world and propose explanations based on evidence they gather |
| hypothesis | A possible answer to a scientific question that is stated in measurable terms |
| mass | Amount of matter in an object does not change with your location |
| data/data collection | The result of your experimentation facts figures and other evidence that you usually record on a chart and then make a graph |
| qualitative observations or qualitative data | Descriptions that cannot be expressed using numbers but instead describe with words |
| evaluation | Looking back over an investigation or experiment to see if there were mistakes, biases, or flaws in the design |
| volume | amount of space an object occupies |
| variable | all of the factors that can affect an experiment |
| controlled variables/constants | all of the factors in an experiment that must stay the same so that you can find out if the change the (IV) or test variable had an effect |
| ethics | rules that enable people to know right from wrong |
| bias | personal opinion slanted toward oneÕs own opinion |
| personal bias | when a person's likes or dislikes influence he or she thinks about something |
| cultural bias | When the culture in which a person grows up affects the way that person thinks |
| experimental bias | a mistake in the design of an investigation that makes a certain result more likely |
| scientific theory | set of statements developed to explain a group of facts or events especially one that has been repeatedly tested or is widely accepted; used to make predictions about natural events or facts and can change as new technology gives new information |
| scientific law | A statement that describes unchangeable relationships among facts and events and tells how something in nature always behaves or acts under certain conditions |
| purpose/problem/question | the reason for doing an experiment, the question to be investigated |
| science | the process of trying to understand the world around us through exploration, invention and solving problems |
| data analysis or interpreting the data | studying the data of an investigation or experiment and looking for trends or patterns in the data or graphs to see if the (IV) had an effect |
| control or controlled group | the standard use for comparison in a controlled experiment |
| procedure or part of an experimental design | the steps you plan to take in an experiment or investigstion |
