Map a habitability boundary

Run four assigned ε cases. Combine the group’s observations, then bracket—not guess—the boundaries.

Class / period:  

1 · Prediction and reason

I think the transition will occur near ε = ___ because…

2 · Observed model outcome

3 · Evidence from the runClaim

  1. 1.Bracket the lower transition with two tested values.

  2. 2.Bracket the upper transition with two tested values.

  3. 3.Which next two values would you test, and why?

Exit ticket

A boundary bracket is stronger than a guess because ___.

The fusion limits 0.006 and 0.008 are pedagogical thresholds in the fate engine. Real stellar and nuclear outcomes depend on more physics and continuous distributions.

Teacher key: expected outcomes are model outputs, not observations of real alternate universes.
