Scientific Method 2

You may not realize it, but you do problem solving every day. You do not always think about how to solve a particular problem. You solve problems in sort of a ‘natural’ way, a way that seems to “make sense” and it usually does.

For example, suppose you put your key into your house door and try to turn it, but it does not budge. You wonder what’s wrong. You examine the key to make certain that it is the correct one. Then you try again. The key still does not turn. What next? You might “jiggle” the key or, you might pull back on the doorknob as you try to turn the key. One of these approaches might work. If not, you try other methods until the problem is solved.

Without knowing it, you solve problems very much like a scientist does. You use scientific method. Scientific method is a guide used to solve problems. It involves asking questions, making observations, and trying things out in an orderly way. Scientists use certain steps to solve problems.
The steps of the scientific method are:

IDENTIFY THE PROBLEM- usually in the form of a question.

GATHER INFORMATION- research, ask questions, and discover what is already known about the problem.

STATE A HYPOTHESIS- a hypothesis is a suggested solution as to why something happen.

TEST THE HYPOTHESIS- experiment and examine the situations to check the hypothesis.

COLLECT DATA- gather all the qualitative/ quantitative data, put it in order, and keep careful records.

ANALYZE DATA- Scientists often use charts and tables to organize data to figure out the meaning of the data

STATE A CONCLUSION- explain the results of the data. What to include in your 3-sentence conclusion:
1. State your hypothesis
2. State whether or not your hypothesis was supported or not supported.
3. Use data as evidence that shows whether not your hypothesis was supported.
