The "How To" manual for Science

What is the Scientific Method?

The "Scientific Method" is a process or set of steps taken to produce reliable results to answer a specific question in a scientific investigation.

• Identify a problem/question

• Make observations

• Conduct research

• Formulate a hypothesis

• Test your hypothesis

• Write a conclusion

• Share results

​Steps of the Scientific Method

​

Multiple Choice

What is the Scientific Method?

• Making predictions about things in science

• Something Mr. Senghor is always rambling on and on about

• Steps that scientists follow during an experiment to get the most reliable answer

• Making guesses and choosing which one sounds the most lit

Multiple Choice

What is the first step in the scientific method?

• Make an observation --> Question

• Design and conduct an experiment

• Make an hypothesis

• Share your results

Multiple Choice

The summary at the end of an experiment that explains the results is... 

• conclusion

• procedures

• materials

• responding variable

Multiple Choice

Stephen predicted that seeds would start to grow faster if an electric current traveled through the soil in which they were planted.

• recognize a problem

• test the hypothesis with an experiment

• form a hypothesis

• draw conclusions  

Repetition

A scientist doing THEIR OWN experiment again to gather more data, eliminate bias, and determine whether the experiment's results support the hypothesis.

Repeated trials.

The SAME scientist repeats the experiment.

Repetition

Used to verify the accuracy and results of the experiment and to find possible flaws in the experiment.

Replication

An attempt to conduct a scientist's experiment by a DIFFERENT scientist/ group by following the procedures to confirm results.

Replication is done to get the same/ similar results to confirm the validity of the experiment and its conclusions.

ANOTHER scientist.

Replication

Used so scientists can check to see if a controlled experiment was conducted and that good scientific practices were used.

This is called peer review.
