songs of a certain species of bird abruptly change. She wants to follow up on her
observations with an inforMal experiMent. Which of the following is the best hypothesis for
explaining the birds’ song changes? (OutcoMe #Ia) (DOK 2) (Paired IteM 1)
A. The bird species switches froM song to warning call whenever it sees a potential
predator.*
B. The bird species has a variety of songs that it sings, regardless of what is happening
in its environMent.
C. The scientist is Mistaken and the songs do not change.
2. A scientist wants to test the hypothesis that a certain bird species in her back yard changes
its songs to warning calls whenever it detects the presence of a potential predator. Which of
the following Most likely describes her initial observations? (OutcoMe #Ia) (DOK 2) (Paired
IteM 2)
A. The scientist noticed that whenever she opened a door to her house, she heard birds
beginning to sing.
B. Each tiMe the scientist let her cat outside, the birds abruptly changed their songs.*
C. The scientist noticed that the birds only appeared at certain tiMes of the day, always
singing the saMe song during those tiMes.
3. What is the Main purpose of conducting experiMents? (OutcoMe #Ib) (DOK 1) (Paired
IteM1)
A. proving a theory
B. Making initial observations
C. disproving a hypothesis*
4. The atteMpt to disprove a hypothesis is accoMplished by which of the following tasks?
(OutcoMe #Ib) (DOK 1) (Paired IteM 2)
A. conducting experiMents*
B. Making initial observations
C. proposing a theory
5. A scientist wishes to test a new antibiotic’s ability to treat stubborn bacterial infections. He
tests his hypothesis that the antibiotic works better than existing treatMents by giving
bacterial infections to Mice and treating theM with the antibiotic. He then deterMines how
Many of the Mice recover froM their infections. What is Missing froM his experiMental
design? (OutcoMe #Ib) (DOK 3) (Paired IteM 1)
A. He is Missing a control group of Mice that received a half dose of the new antibiotic.
B. He is Missing a control group of Mice that did not receive the new antibiotic.*

C. Nothing is Missing—he has done everything he needs to do for this to be a successful
experiMent.
6. A scientist wants to deterMine whether a new cheMical she isolated can cure a certain
disease. To test her hypothesis that the new cheMical cures the disease More effectively
than current treatMents, she infects Mice with the disease and gives theM the new
cheMical. She then assesses how Many Mice were cured of the disease. What is
MissingfroM her experiMental design? (OutcoMe #Ib) (DOK 3) (Paired IteM 2)
A. She is not Missing anything—her experiMental design is adequate to test her
hypothesis.
B. She is Missing a control group of Mice that received a half dose of the new cheMical.
C. She is Missing a control group of Mice that did not receive the new cheMical.*
7. A scientist believes that she has found a new life forM. Which of the following conditions is

another.
B. The creature’s body is bilaterally syMMetrical.*
C. The creature seeMs to react to being touched.
8. A scientist discovers a putative new life forM and notes that the creature’s body is bilaterally
syMMetrical and consequently satisfies the criteria for defining life in which of the following
categories? (OutcoMe #Ic) (DOK 2) (Paired IteM 2)
