Question 1
Sarah looked at some pond water with a microscope. She used the low-power objective
lens to look at some green algae. If Sarah switched the lens from low power to high power
what would she see in the field of view?
A. A lot more cells than with the low-power view, but in lesser detail
B. The same number of cells as with the low-power view, but in lesser detail
C. The same number of cells as with the low-power view, but in a greater detail
D. Fewer cells than with the low-power view, but in greater detail
CORRECT ANSWER
D. Fewer cells than with the low-power view, but in greater detail
Question 2
In the laboratory investigation where students are tasked with measuring the rate of
change of a ball rolling down a ramp, students must collect data from a stop watch as the
ball rolls down the ramp. The teacher sets the minimum of trials to measure at five.
How does the use of repeated trials reduce the amount of error in the experiment?
A. Repeated trials allow the students to become familiar with the equipment as well as offer
more time to process the information from lecture
B. Repeated trails reveal the pattern of the scientific phenomenon which is the subject of
the experiment. If the concepts do not revel them selves, students must conduct more trials.
1
,C. Repeated trials allow students to determine if their data collecting techniques produce
accurate and precise data. The analysis determines if the data is accurate
D. Repeated trials allow students to collect more data and ensure that the data collected is
CORRECT ANSWER
D. Repeated trials allow students to collect more data and ensure that the data collected
is accurate and precise. If the numbers are not similar, students know that there is an
error in the procedure
Question 3
Students in Mr. Neeve's 5th grade classroom are preparing a presentation highlighting
their garden projects. They want to show data which illustrates the growth of two
sunflowers over a three month period of time. Which of the following is the MOST
appropriate way fro presenting the growth of plants over time?
A. A bar graph
B. A line graph
C. A pie graph
D. A chart showing all of the measurements for a three month period of time
CORRECT ANSWER
B. A line graph
Question 4
When cleaning the cage of the turtle in the classroom, the teacher must ensure that
students wash their hands when finished because of the risk of illness due to which of the
following -
A. Salmonella bacteria that live on the exterior of some reptiles
B. E. coli. bacteria that can contaminate the eggs of some reptiles
2
,C. Various viruses that inhabit the crevices of the reptile exteriors
D. Infection from a potential bite when handling and moving the turtle
CORRECT ANSWER
A. Salmonella bacteria that live on the exterior of some reptiles
Question 5
A box on a table is subjected to a push from the left. At the same time, it is subjected to a
push with greater force directly opposite on the right. Which of the following statements
describes what will happen to the box?
A. The box will move at an angle perpendicular to the applied forces
B. The box will move toward the left side of the table
C. The box will move back and froth on the table
D. The box will rotate in a counter-clockwise motion
CORRECT ANSWER
B. The box will move toward the left side of the table
Question 6
In a science experiment, 10 mL of Solution A are added to a test tube containing 10 mL of
Solution B. The test tube is immediately sealed with a rubber stopper. The two solutions
are both clear and colorless. As the solution mix, the test tube becomes warm and the
contents become cloudy. Finally, as the test tube is left undisturbed for several minutes, a
white solid settles to the bottom of the test tube covered by a layer of clear, colorless
liquid. Which of the following is a correct conclusion about this chemical system from the
beginning to the end of the experiment?
A. The total mass of the system remains unchanged
B. The identities of the chemicals in the system remain unchanged
3
, C. The total energy of the system remains unchanged
D. The densities of the materials in the system remain unchanged
CORRECT ANSWER
A. The total mass of the system remains unchanged
Question 7
How do rubrics and spending time reviewing expectation foster success in the classroom?
A. Having a no secrets class means that grades are not a secret. Reviewing expectations and
sharing assignment requirements communicates evaluation criteria
B. Rubrics allow teachers to list everything they want to see on a finished product of an
assignment, which ensures all standards are covered for the unit
C. Communicating success criteria in a rubric teaches students the vital details necessary to
grasp the concepts of a standard within a unit of study
D. After an assessment, teachers create a rubric fro re-teaching assignments. The rubric lets
students know their weaknesses to focus on during the redo sessions.
CORRECT ANSWER
A. Having a no secrets class means that grades are not a secret. Reviewing expectations
and sharing assignment requirements communicates evaluation criteria
Question 8
Ms. Corpora wants her sixth-grade students to understand the process used in scientific
investigation. She wants them to realize that scientists continually form a hypothesis
about ways to solve a problem, test the hypothesis, form a conclusion, and then revise the
hypothesis and begin the process again until the problem is solved. Which of the following
activities would MOST effectively help students understand this?
