BIOLOGY 1ST SEMESTER FINAL 2023

A series of steps used by scientists to solve a problem or answer a question. 

• scientific method
• recipe
• data collection
• metric system

A testable explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

Testing a hypothesis often involves a(n):

• answer
• experiment
• problem
• safety check

This variable in an experiment is the one being changed by the scientist. 

• dependent variable
• independent variable
• data
• control group

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

• The type of plant
• The amount of sunlight
• The type of music
• The type of liquid

Dependent variable means

• the scientist controls what to test
• educated guess
• ask a question
• what is being measured

If I ride my bike to school instead of walking, then I will get to school faster. What is the dependent variable?

• True
• How fast you get to school
• Riding a bike or walking
• False

Will a construction paper air plane fly faster than an airplane made from notebook paper? Choose the best hypothesis.

• If I make a paper airplane from notebook paper, then it will fly faster than construction paper.
• Yes.
• No.
• I think the construction paper air plane will fly faster.

If I read this question carefully, then I will answer it correctly. What is the independent variable?

• I hope so
• Yes
• Reading or not reading carefully
• Likelihood of a correct answer

This is the group that we will compare our experimental group to. This group stays "normal."

• Control Group
• Experimental Group
•  Normal Group
• Weird Group
