Scientific Method Lesson 1

Scientific Method Steps used by scientists to help them solve problems.

Steps  State the Problem  Make an observation.  Make a Hypothesis.  Experiment  Record / Analyze and draw a conclusion.

Observations  Taken using your 5 senses.  Seeing  Hearing  Smelling  Touching  Taste (although not in lab) AH—Look at this!

Hypothesis  A testable prediction to explain observations.  Educated guess.

Experiment You figure out a way to test whether hypothesis is correct. The outcome must be measurable. (quantifiable)

Results You do the experiment using the method you came up with and record the results. You repeat the experiment to confirm your results by retesting..

Conclusion  Summary  Finalize all your data.

Theory  Explanation based on many observations and supported by results of many experiments.  A theory may be revised or replaced with another theory as tests are done.

Scientific Law  A fact of nature that is observed so often that it becomes accepted as truth.

Alchemy  A pseudo science.  Started with the idea of making gold from other materials.  Their experiments and records help to establish data for future scientist.

Chemistry  The study of science that attempts to explain the structure and the properties of matter.

Organic Chemistry  Study of compounds containing carbon.
