In the water cycle, energy from the sun heats the water, changing the liquid water into a
gas. It loses energy and falls back to Earth. Which step in the water cycle is depicted by
#1 in the diagram shown? Answer: condensation
Carbon (C) is classified as which of the following? Answer: element
Following an investigation on how the length of shadows changes throughout the day,
Mr. Vasquez would like to assess his students' knowledge of the relationship between
shadow length and time. Which of the following would be the best assessment to use?
Answer: having students draw pictures of shadows at various times of the day
Mr. Harris has several English-language learners in his classroom. He is currently
beginning a unit about circuits. Which of the following activities will be most effective in
engaging Mr. Harris' English-language learners in a lesson? Answer: giving students
bulbs, batteries, and connecting wires and asking them to try to make the bulbs light up
A student measures the volume of 12.8 ml of liquid with a graduated cylinder, checking
the measurement three times to obtain volumes of 13.2 ml, 13.2 ml, and 13.1 ml. The
student's measurements are: Answer: precise but not accurate.
Global weather patterns or short-term climatic changes can be impacted by which of the
following? Answer: changes in global winds and ocean currents
During a unit on organisms and environments, Mr. Woodland wants his second-grade
students to identify factors in the environment that affect plant growth. Students design
investigations that involve growing bean plants in paper cups and exposing the plants to
environmental variables of their choice. After the beans sprout, the students measure
and record the heights of their bean plants. At the end of the investigation, students will
be asked to present their data in a way that will be quick and easy to understand. Which
of the following is the best way to incorporate technology into this lesson? Answer:
Have students record and graph their data in a spreadsheet that they can access each
time they make a measurement.

the following statements correctly compares the Moon's gravitational force on Apollo 11
with Apollo 11's gravitational force on the Moon? Answer: The Moon and Apollo 11
exerted the same amount of force but in opposite directions.
As a demonstration during a unit on plate tectonics, a teacher holds an aluminum pie
plate over a smoky candle and has the students observe how the smoke spreads and
moves around and over the edges of the plate. Which of the following is demonstrated
by the movement of the smoke? Answer: convention
A tug-of-war rope is being pulled with a force of 80 N to the left by Jeff and a force of 50
N to the right by Rico. What is the net force acting on the rope? Answer: 30 N to the left
Which of the following is true about stars? Answer: Star color is dependent upon their
temperature.

the following tools would be most appropriate for her to use? Answer: graduated
cylinder
Which of the following is the best example of a behavioral adaptation? Answer: Grizzly
bears in Alaska will hibernate in the winter.
Which activity would be appropriate for a second-grade class studying the water cycle?
Answer: having groups use easily accessible materials (such as rocks, popsicle sticks,
etc.) to build a 3D model of the water cycle
Heart disease is a major threat to human life in the United States. Which of the following
lifestyle changes is the most likely to reduce the incidence of heart disease? Answer:
increasing the amount of exercise
Certain plant species can reproduce asexually through the processes of budding or
through spore dispersal. Which of the following is a disadvantage for plants that employ
this type of reproduction? Answer: All offspring are genetically identical, so a disease
can wipe out an entire population.
Mrs. Conner wants to pre-assess the class regarding their knowledge of the periodic
table of elements, inquire about their interest in the subject, then follow up with what
students have learned. Which of the following formative assessment tools would be a
good choice for Mrs. Conner? Answer: K-W-L chart
Students perform an investigation to compare the relative specific heats of sand, water,
and soil. They fill plastic cups with the same mass of each material, place a temperature
probe in each sample, and put the samples the same distance beneath identical flood
lamps. Students record temperature data for 2 minutes while the lamps are on, and
