| A | B |
|---|
| independent variable | the manipulated variable-the variable that is purposely changed |
| dependent variable | the responding variable- the one measured to see how it responded to the purposeful change |
| hypothesis | a statement that attempts to answer the question or problem; showing the relationship between the independent and dependent variables |
| controlled variables | those factors that remain unchanged in an experiment |
| experiment | a step-by-step process designed to test the relationship between selected variables |
| notebook | the researcher's documentation of experimental data- |
| scientific method | a systematic process for solving problems and discovering answers to questions |
| Quantitative observation | Data that describes with numbers |
| Qualitative observation | data that describes with words, colors, texture etc. |
| Variable | anything that can change in an experiment |
| Length | measure of distance between two points |
| Mass | the amount of a matter in a substance |
| Volume | How much space a substance takes up |
| Weight | measure of gravity pushing on a substance x its mass |
| Hypothesis | the possible solution of a problem; should be based on research |
| SI | System Internationale - scientific measuring system; also known as the metric system |
| conclusion | the decision made about the outcome of an experiment; usually based on how well the actual result matches the predicted result based on data and observations |
| data | the results of specific trials or tests completed during experiments, information |
| evidence | support for the idea that something is true |
| inference | a conclusion or deduction based on observations |
| observation | any information that is collected with any of the senses |
| opinion | ideas that people have that may or may not be based in fact |
| OBSERVE - You notice something in your world that intrigues you. | step 1 of scientific method |
| QUESTION- You question what you saw and wonder why? how? what if? will it...? | step 2 of scientific method |
| RESEARCH- Gather from books, teachers or other informed sources to see what has already been discovered about this subject. | step 3 of scientific method |
| FORM A HYPOTHESIS- Create an educated guess to answer your question. (Be sure your variables are in your hypothesis!) | step 4 of scientific method |
| EXPERIMENT- Form a study that tests your hypothesis using variable factors and constant factors. Gather qualitative and quantitative data! | step 5 of scientific method |
| ANALYZE DATA & DRAW CONCLUSIONS- Make charts, figures, graphs and see if you found an answer to your question. | step 6 of scientific method |
| SHARE THE INFORMATION & REPEAT THE PROCESS- Other scientists will be able to check your conclusions and use your information to support their findings | step 7 of scientific method |
| meter | base SI/metric unit for length/distance |
| gram | base SI/metric unit for mass |
| liter | base SI/metric unit for volume |
| prediction | a statement made about the future |
