Honors Biology Scientific Method Review

In order to make an inference, you must have:

• Make observations with all senses
• Made 3 other observations
• Background knowledge
• A hypothesis in mind first

Which of the following is NOT a characteristics of a hypothesis?

• Must be made with background knowledge

• Must be testable

• Must organizes the IV and DV

• Must always be correct

The step of the scientific method that would come after testing is:

• Inferencing
• Hypothesizing
• Peer Review
• Analyzing Data

The easy way to pick out an experiments responding (DV) variable is to look for:

• What was purposefully changed
• Number of trials
• What's being measured
• The test group

The test group gets its name because this scientific variable is applied to this group:

• Manipulated
• Responding
• Dependent

The control group , or the normal group, is needed for:

• Keeping aspects of experiment constant

• Comparison

• Hypothesis formation

• Application of the manipulated variable

If I add sliced garlic to my aquarium water, then my fish will eat a lot. The IV in this hypothesis is:

• Adding garlic to the aquarium

• The fish eating a lot

A good experiment will yield accurate results if it has:

• A really strong hypothesis
• Only one manipulated variable
• 1 or 2 trials maximum
• Two separate responding variables.

• recognize a problem
• test the hypothesis with an experiment
• form a hypothesis
• draw conclusions
