Question 1
According to the Next Generation Science Standards (NGSS), what is the primary purpose of
science and engineering practices in elementary education?
A) To memorize scientific facts for standardized tests
B) To engage students in behaviors that scientists and engineers use to investigate the world
and solve problems
C) To replace content knowledge with hands-on activities only
D) To focus exclusively on reading science textbooks
Answer: B) To engage students in behaviors that scientists and engineers use to investigate
the world and solve problems
ratiOnalE: NGSS emphasizes practices such as asking questions, developing models,
planning investigations, analyzing data, and constructing explanations. These practices build
both content knowledge and process skills, not just memorization.
Question 2
Which of the following is an example of a crosscutting concept as defined in the NGSS?
A) Life cycles of butterflies
B) The periodic table of elements
C) Cause and effect
D) The rock cycle
Answer: C) Cause and effect
, ratiOnalE: Crosscutting concepts are overarching themes that apply across all scientific
disciplines. NGSS identifies seven crosscutting concepts including patterns, cause and effect,
scale proportion and quantity, systems and system models, energy and matter, structure and
function, and stability and change.
Question 3
A first-grade teacher asks students to sort pictures of animals into groups based on where
they live (forest, ocean, desert). This activity primarily addresses which science and
engineering practice?
A) Analyzing and interpreting data
B) Using mathematics and computational thinking
C) Developing and using models
D) Obtaining, evaluating, and communicating information
Answer: A) Analyzing and interpreting data
ratiOnalE: Sorting pictures into categories based on observable characteristics is a form of
analyzing and interpreting data at an early elementary level. Students are organizing
information to identify patterns, a fundamental data analysis skill.
Question 4
Which disciplinary core idea in physical science is most appropriate for kindergarten students
to explore through hands-on activities?
A) Chemical bonding and molecular structure
B) Newton's laws of motion
C) Push and pull forces (cause and effect relationships in motion)
D) Conservation of mass in chemical reactions
Answer: C) Push and pull forces (cause and effect relationships in motion)
ratiOnalE: NGSS K-PS2-1 expects kindergarteners to plan and investigate how pushes and
pulls can change an object's motion. This directly addresses cause and effect in motion at an
appropriate developmental level for young learners.
