HS-LS4-2 Biological Evolution: Unity and Diversity Science Phenomena
Human-Crafted Phenomena for the NGSS
Not all assessments are created equal. Unlike generic question banks or AI-generated items, InnerOrbit’s HS-LS4-2 content is built by a team of teachers and science leaders who deeply understand the NGSS and the realities of today’s classrooms.

Performance Expectation HS-LS4-2
Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment
What Makes Our Content Different?
Expertly Crafted, Not Auto-Generated
Every question and phenomenon for MS-PS3-1 is thoughtfully designed by educators. Our team ensures each item encourages authentic sensemaking rather than surface-level recall.
Discreetly Tagged for Rich Data
Each question is carefully tagged by dimension (DCI, SEP, CCC) and other criteria, producing detailed reports that highlight where students are thriving and where they need support.
Tailored to Match Your Curriculum
We spend time aligning our questions to different district curricula and instructional needs, so teachers can integrate them seamlessly into their classroom flow.
Actionable, Not Just Informative
Our assessments don’t just give scores — they generate instructionally useful data that helps teachers make smarter, more frequent adjustments.
