Physical ScienceChapter 2 – The Scientific Method

Chapter Objectives1. Discuss the steps of the scientific method

and apply them to real-world situations2. Evaluate the types of data in

experimentation and suggest ways data can be corrupted or misinterpreted

3. Use theories and laws to establish workable scientific activities

4. Emphasize the importance of communication in scientific endeavors

5. List and give examples for each of the limitations of science, especially as they relate to origins and value judgments.

Scientific MethodThe Scientific Method is a ___________, __________ approach to finding a solution or explanation of a problem.

Scientific Method1. Clearly __________ and __________ the

problem Keep it simple

2. Form a __________ Hypothesis – a proposed __________ to the

__________ Requires __________ More than an “____________ __________”

Scientific Method3. Perform ___________

__________ experiment – an experiment where all factors in the experiment are controlled except one experimental factor (___________)

The group(s) with the variable are called __________ groups

The group without the variable are called __________ group

Scientific Method Information gathered from the

experiment is called ___________ __________________ data – non-numerical

data such as color, texture, etc. __________________ data – numerical data

such as measurements Scientists use controlled experiments

that collect quantitative data as much as possible to propose solution to problems

Scientific Method5. _________ the data

Information is analyzed by classifying and organizing the data so that trends and patterns can be seen

Scientific Method6. Make a ___________

Using the data, scientists come up with a solution to the problems

Good conclusions should:1. Relate to the __________________ 2. Account for the __________________ 3. Predict the __________________ 4. Stay as __________________ as possible

Scientific Method7. _____________ the conclusion

_____________ the experiment to verify the conclusion

Use the conclusion to make ____________ for future experiments

Theories vs. Laws __________ a partially verified idea that

ties together a number of different observations. They attempt to explain ____________ for observations Where did we come from?

____________ describe consistent patterns in nature _____________ observations)
