STEM Next Generation Science Standards 2

Question 1

Which Disciplinary Core Idea (DCI) domain addresses how organisms interact with their environment and each other?

Accepted Answer

Life Sciences

Answer

Life Sciences DCIs (LS1–LS4) cover ecosystems, heredity, evolution, and organism interactions with the environment.

Question 2

In NGSS, the DCI 'PS3: Energy' specifically emphasizes that students should understand energy as:

Accepted Answer

A property of objects and systems that can be transferred and transformed

Answer

PS3 frames energy as a property that can be transferred between objects and transformed between forms, not as a substance.

Question 3

Which NGSS DCI focuses on plate tectonics and large-scale system interactions within the Earth?

Accepted Answer

ESS2: Earth's Systems

Answer

ESS2 covers Earth's systems including plate tectonics, the rock cycle, and interactions among the geosphere, hydrosphere, atmosphere, and biosphere.

Question 4

A performance expectation at the middle school level requires students to 'develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.' Which DCI does this primarily address?

Accepted Answer

LS2: Ecosystems: Interactions, Energy, and Dynamics

Answer

LS2 addresses ecosystem interactions including cycling of matter and energy flow among biotic and abiotic components.

Question 5

Under the NGSS DCI 'ETS1: Engineering Design,' what is the primary purpose of defining constraints and criteria?

Accepted Answer

To specify what a successful solution must do and what limits it must work within

Answer

Criteria define what a successful solution must achieve; constraints define the boundaries (cost, materials, time) within which solutions must operate.
