Stage- and age-structured population modeling resources for growth, decline, survivorship, and fecundity.

Curriculum Alignment

Life Cycle Modeler curriculum alignment

This page maps the app to NGSS-relevant concepts and practices while keeping the app connected to the larger evo-edu curriculum frame.

Alignment Notes

  • NGSS HS-LS2-1: Use mathematical or computational representations to support explanations of carrying capacity and ecosystem factors.
  • NGSS HS-LS2-6: Evaluate claims and reasoning about complex interactions in ecosystems.
  • Science and Engineering Practices: using mathematics and computational thinking, analyzing and interpreting data.

Classroom and Independent Use

K-12 or workshop use

Use the app to move from abstract matrix terms to decisions about persistence, vulnerability, and management, then ask learners to justify which stage matters most.

Self-directed use

Work through the guide as a demographic case study: predict which stage should matter, run the model, then revise your explanation if another stage turns out to dominate the outcome.

Use in Sequence

Before the app

Introduce the life history and ask which stage should matter most to growth rate or persistence.

During the app

Change one stage-specific variable at a time and compare projections rather than treating the matrix as abstract math only.

After the app

Connect the results to conservation, management, or disturbance scenarios affecting real populations.

Evidence of Alignment in Practice

What learners should produce

  • A prediction about which life stage will most affect growth or decline.
  • A comparison of projections from at least two stage-specific changes.
  • A revised explanation when the model highlights a different vulnerable stage than expected.

What to listen for

  • Reasoning that connects stage structure to long-term outcome.
  • Claims justified with projection behavior rather than intuition alone.
  • Attention to how management or disturbance questions change the interpretation.

Scientific Virtues in Use

Use this app to reinforce careful observation, evidence-based explanation, and willingness to revise claims after repeated runs or conflicting results. That guidance is expanded in the Scientific Virtues notes.
