Observations:
• Are the “keystone” to Science.• If it can’t be “observed”, it can’t be studied by the
Scientific Method.• Can be made through your senses or through
the use of tools.

Scientific Method:
• Outlines a series of steps for answering questions.
• Obtains “evidence” through the use of experiments.

Summary
• We will see the “themes” at various times throughout the course.
• AP Biology students must be able to design an experiment to test a hypothesis.
• Why? This is a national exam test item.
