Scientific Method and TAILS for graphing.
| Question | Answer |
|---|---|
| Purpose/Problem | During this step of the Scientific Method you ask yourself "What do you want to learn?" |
| Research | During this step of the Scientific Method you find out as much about your topic as you can. |
| Hypothesis | In this step of the Scientific Method you predict the answer to the purpose/problem. |
| Experiment | This is the step where you design a test to confirm or disprove your hypothesis. |
| Analysis | You record what happened, look at and interpret the data. |
| Conclusion | During this step you answer the question, "Does the data support my hypothesis?" |
| control | The factor in an experiment that remains the same. |
| dependent variable | This is the factor that is being tested. |
| independent variable | The factor that affects the value of the dependent variable. |
| What does the T in TAILS stand for? | T stands for title. It may be written as a statement or it may ask a question. |
| What does the A in TAILS stand for? | A stands for axes. the dependent variable goes on the Y axis and the independent variable goes on the X axis. Remember, DRY MIX. |
| What does the I in TAILS stand for? | I stands for intervals. Intervals on each axis must be equally spaced. |
| What does the L in TAILS stand for? | L stands for labels. Both axes must be labeled and units included if applicable. |
| What does the S in TAILS stand for? | S stands for scale. the data points must fill the graphing area. |
| When do you use a bar graph? | You use a bar graph to compare two or more things. |
| When do you use a line graph? | You use a line graph to show how something changes over time or to show the relationship between two quantities as those quantities are changing. |
| When should you use a pie graph (circle graph)? | This graph gives you a quick view of the relationships among parts of a whole. |
