Observing |
Simply being aware of, curious about he occurrences in your surroundings. |
|
|
Reflecting on the implications of our observations |
Thinking through what was observed and relating them to other known facts. Often there is an attempt to determine cause and effect. Scientists will often consult literature in an effort to pull together all present information which has bearing on their observations |
|
|
Proposing a hypothesis which explains what has been observed within the context of current knowledge |
The "I bet I know what caused that!" statement. Scientists have no special claim for this step, but they may formalize it by actually writing it down along with reasons for their guess |
|
|
Devising of an experiment which will test the hypothesis |
Scientist, realizing that there may be other factors influencing their observations in addition to the one singled out hypothesis, will try to devise an experiment or collect enough data to eliminate each factor (constants) except he one in question (variable) |
|
|
Accepting, rejecting or modifying the hypothesis |
Based on the data of the experiment, the scientist must logically determine whether the hypothesis has been supported or refuted. No "right" or "wrong" answer. An experiment which refutes a hypothesis can often be more enlightening than one which substantiates the present understanding of the problem |

Steps of the Scientific Method |
|
|
Negative control |
A sample or event that is not exposed to the testing procedure. |
|
|
Helps scientists begin their study of a particular topic. |
Why does the scientific method being with observations? |
|
|
Helps scientists decide how an experiment will be conducted |
What is the benefit of formulating a hypothesis? |
|
|
A well designed experiment must have a negative control that is not exposed to the testing procedure. If the negative control and the test produce the same results, either the procedure is flawed or the hypothesis is false. |
Why is the purpose of a negative control? |
|
|
So it can be easily examined by others |
Why must a scientist keep complete records of an experiment? |
|
|
To determine whether their data support or do not support their hypothesis |
What is the purpose of the conclusion? |
|
|
Scientific theory |
An encompassing conclusion based on many individual conclusions in the same field. Takes many years to develop. |
|
|
Hypothesis |
Input from various sources is used to formulate a testable statement |
|
|
No. You must have a positive and negative control. |
Is it sufficient to do a single experiment to test a hypothesis? |
|
|
Negative control |
What do you call a sample that goes through all the steps of an experiment but does not contain the factor being tested? |
|
|
To single out the variable being tested. |
Why is it important to test one substance at a time when doing an experiment? |
