Scientific Method
Define parts of the scientific method
Term | Definition |
---|---|
Step 3: Hypothesis | This is pretty much a guess at what might happen in an experiment, BUT it isn't just a random guess. Making a hypothesis means we have to think about what we, or others already know. We record this BEFORE we conduct an experiment. |
Variable | This is something that can change. Lots of things are variables, for example: Amount of something (5grams, 10 grams, etc), or time for a reaction to happen (1 minute, 40minutes, etc). |
Independent Variable | In an experiment, the variable that scientists control is the independent variable. That means the other variable(s) don't affect it. For example: The types of paper towel used to test absorbency. |
Dependent Variable | In an experiment, the dependent variable might change when the independent variable is changed. For example: Different amounts of water might be soaked up by different types of paper towel. The amount of water is DEPENDENT on the type o paper towel. |
Step 4: Method | This is a series of steps that outline how to perform an experiment that may answer our initial question, and either support or disprove our hypothesis. We need to record this so others can repeat the experiment and help confirm our results. |
5. Experiment | This is the part where we follow the method in order to test our hypothesis. |
Step 6: Results | Collecting measurements and observations of what happens before, during and after an experiment create our results. They are an important part of answering our question. |
Step 7: Conclusion | This is what we do after collecting and looking at the results from our experiment. We relate our results back to our hypothesis and question. |
Control | Part of an experiment designed to show if anything else is affecting the results. For example, |
Observation | This is anything that you see, hear, smell or feel. It is good practice to record your observations (write them down or video them!) |
Scientific Method | It's a process that we use in science, so that we can get the best possible answers to our questions. It goes like this: 1. Question. 2. Research. 3. Hypothesis. 4. Method. 5. Experiment. 6. Results. 7. Conclusion. |
Step 1: Question | Something that inspires further investigation. |
Step 2: Research | We do this to help ourselves understand more about what we will investigate before we begin developing our experiment. |
