Introduction to Science Test

An observation is:

• using one or more of your senses to gather information.
• a testable guess.
• a prediction about the future.
• an interpretation based on observations and prior knowledge.

An inference is:

• using one or more of your senses to gather information.
• a testable guess.
• a prediction about the future.
• an interpretation based on observations and prior knowledge.

Observations can be divided into two types:

• Quantitative & Qualitative
• Independent & Dependent
• Constants & Controls
• Positive & Negative

True or False? A quantitative observation deals with characteristics and cannot be expressed in numbers. Examples include color, shape, size, and texture.

• True
• False

Inferences are always correct.

• True
• False

A prediction is a forecast of what will happen in the future, based on

• what you want to see happen.
• what your friends say will happen.
• what the weatherman says will happen.
• past experience or evidence.

A series of steps that scientists use to solve a problem is called:

• Hypothesis Inquiry
• Control Test
• Variable Process
• Scientific Method

What is the first step of the scientific method?

• Develop a conclusion
• Form a hypothesis
• Ask a question
• Analyze the data

When a scientist tests a hypothesis, they are performing a(n):

• observation
• experiment.
• conclusion.
• theory.

Which step of the scientific method involves using graphs and charts to visualize data?

• Make an observation
• Analyze results
• Ask a question
• Communicate results with a report
