Scientific Method
Steps and Application of the scientific method
| Question | Answer |
|---|---|
| What is the first step in the scientific method? | Make an observation |
| What comes after making an observation? | Form a question |
| Once a question is formed, what comes next? | Make a hypothesis |
| When we have a hypothesis, we then have to ______________. | Test it with an experiment |
| What is an independent variable? | The variable that the scientist changes on purpose to see if it effects other things |
| What is a dependent variable? | The variable the scientists is measuring in the experiment; it changes in response to the independent variable |
| What is a control variable? | Variables that stay the same throughout the experiment so that we know they are not affecting the outcome |
| What is a control group? | The group that doesn't get treatment; we consider this the "normal" group |
| What do scientists do if the hypothesis is supported? | Retest the experiment many times to make sure they get the same result |
| What do scientists do if the hypothesis is not supported? | Go back and change either the hypothesis or the way the experiment is done |
| Once scientists draw conclusions about an experiment that is done many times, they then _________________. | Communicate the results with other scientists |
| How is a theory different from a hypothesis? | A hypothesis is a possible answer to the posed question (more like a guess), but a theory has been well-tested and proven time and time again |
| What is a hypothesis? | A possible answer to the posed question which is testable. |
| What is qualitative data? | Data without numbers; describes quality |
| What is quantative data? | Data with numbers; describes quantity |
| "I noticed that my back hurts at the end of the day" is an example of this step of the scientific method. | Observation |
| "I wonder what is causing my back to hurt" is an example of this step of the scientific method. | Question |
| "I think that the shoes I'm wearing are causing my back to hurt" is an example of this step of the scientific method. | Hypothesis |
| If I do an experiment where I wear different shoes on back to back days to see how much my back hurts at the end of the day, what is the independent variable of this experiment? | The different shoes |
| If I do an experiment where I wear different shoes on back to back days to see how much my back hurts at the end of the day, what is the dependent variable of this experiment? | How much my back hurts |
| If I do an experiment where I wear different shoes on back to back days to see how much my back hurts at the end of the day, what are some control variables of this experiment? | Same person, same amount of standing, same type of floor to stand on |
