Scientific Method An Investigation System
From the beginning of time, people have wondered how and why things happen in the world.
Many people did not know why things happened. Not knowing what was going on was surprising and sometimes scary.
Since everything was a mystery, people made up stories to explain things. The smoke flies up to the moon and hides part of it.
But some people used their brains. They asked questions, “How does this happen?” or “Why did that happen?” They made predictions about what might happen.
They decided to watch and observe very carefully.
Pretty soon they were able to describe things they saw, such as: objects organisms events
Next they tried out some tests to see what might happen.
That was the beginning of SCIENCE! Round shapes roll very well! I think I may have invented the wheel!
Good thinkers organized this investigation into a system. That’s how the was born.
The scientific method is simply a procedure scientists use to explain why things happen the way they do.
The Scientific Method has six parts: 1.Problem 2.Hypothesis 3.Materials 4.Procedure 5.Observations 6.Conclusion
Problem State the problem in a question. Ask yourself, “What am I trying to find out?” Ask
Hypothesis: Make a prediction. What do you think will happen? Think
Materials: What do I n eed to work the experiment? Need
Variables: What can I change to try the experiment again? time materials quantity Change
Procedure: What are the steps I must do to work the experiment? Do
Observations: What can I see and/or measure? See
Conclusion: What did I learn from this experiment? Learn
New Questions: What would happen if I…? ?
The Scientific Method Poem The Scientific Method is the way to go When you absolutely definitely need to know How things happen in our world everyday Scientists help show all of us the way!
