Elementary Content Exam (305) – Science
Questions with Correct Answers 2025/2026
Which of the following technological developments would be most useful in reducing one of the
causes of global climate change? - CORRECT ANSWER -production of efficient and inexpensive
electric cars
Fifth grade students have constructed models of Earth out of paper-mache, using straws for
Earths axis. The students move their models around a light representing the sun, stopping to
rotate it at four positions representing the times of the annual equinoxes and solstices. Which
of the following questions would best help students apply their observations of changes in light
and shadow during the movement of their model planets? - CORRECT ANSWER -Why are all of
the seasons the same at the equator?
Sixth grade students perform an investigation to compare the densities of three rectangular
blocks that are composed of different substances. Lab teams take measurements of each block
using a triple-beam balance. Which of the following scientific tools would best enable the
students to complete their investigation? - CORRECT ANSWER -meterstick
Two ramps set up in a third grade classroom at the same angle; one ramp is covered with
smooth cloth and the other is covered with rubberized matting. At a signal, a student releases a
model car of the same size and structure down each of the ramps. After observing this example,
the class declares that cars move faster on smooth surfaces than matted ones. The teacher
instructs them to perform the same demonstration several more times. Which of the following
areas of scientific thinking will be strengthened for students following their teacher's
instruction? - CORRECT ANSWER -One data point should not be used to generalize a conclusion
Third graders who are beginning to learn about space exploration ask how it is possible to travel
from Earth to the moon. The most effective way for the teacher to introduce the technological
advances related to this achievement is by: - CORRECT ANSWER -providing materials for
students to investigate the movement of balloon rockets
