Scientific method: a series of steps scientists follow to answer questions and solve problems.
The seven steps used in scientific methods are
asking a question
research
forming a hypothesis
testing the hypothesis
analyzing the results
drawing conclusions, and
communicating results.

Notes:
Forming a hypothesis is the third step in the scientific method. A hypothesis is a possible explanation or answer to a question. A good hypothesis is testable by an experiment.

6. Topic: Scientific Method CA standard 8
Questions:
Notes:
Testing the hypothesis: (Materials & Procedures) Scientists test the hypothesis with experiments to find out if it is a reasonable answer to their question.
A controlled experiment compares the results from a control group with the results from experimental groups & is a good way to test a hypothesis.
Data are any pieces of information acquired through observation or experimentation.

Notes:
Analyzing the Results: After scientists test a hypothesis by performing an experiment, they usually analyze their results by using tables and graphs. Analyzing data from repeated tests can help scientists determine if their data are accurate and reproducible.

Notes:
Drawing conclusions: After scientists analyze their results, they draw conclusions about whether their hypothesis was supported. A valid conclusion can only be obtained with reproducible data (which means similar data from many repeated tests).
