Scientific method
Question | Answer |
---|---|
Scientific theory | the most logical explanation for events that occur |
Scientific law | when a hypothesis survives many tests |
Scientific method | a systematic approach to problem solving |
hypothesis | an educated guess about a possible solution or answer to your problem or question (I think...) |
experiment | a test or trial performed in order to discover |
variable | something that can change the results of an experiment. There can only be 1 change in an experiment. |
independent variable | (cause) is the one thing that is changed in an experiment. It is what is being tested. |
dependent variable | (effect) is the change in response to the change or manipulation of another variable. it is the response that can be observed and measured |
constants | the parts of the experiment that are NOT changed. They are kept the same so as not to interfere with the experiment |
control set up | set up exactly like the experiment that contains the variable, but it does not contain the variable |
experimental set up | the set up that does contain the variable |
procedure | sequence of steps involved in performing an experiment |
data | recorded observations and measurements taken |
conclusion | the results or answer to the question |
observation | involves using the senses to examine what is happening |
steps of the scientific method | 1. state the problem or ask the question 2. gather information on the problem 3. form a hypothesis 4. do experiments to test the hypothesis 5. record and analyze data 6. state a conclusion 7. repeat the work |
