These model lessons organize Avida-ED activities around specific evolutionary concepts rather than around a single step-by-step lab sequence.

Best fit​

Use model lessons when:

• you want to target one concept without assigning the full lab manual
• your course already has its own broader unit structure
• students can work with a little less scaffolding and a little more concept focus

Recommended use​

• Use model lessons when you want a concept-centered activity.
• Use the lab manual when students need a more guided sequence.
• Flag older references clearly so students do not confuse legacy interface details with the current version of the software.

Model lesson set​

Each lesson focuses on a single concept connected to the earlier lab manual work, with guided questions, suggested UI checkpoints, and a legacy note about which screenshots or conditional download pages you may need.

• Understanding the Introduction of Genetic Variations by Random Mutation
  Highlights how mutation introduces diversity and which settings drive it.
• From Genotype to Phenotype
  Connects changes at the genetic level to observable traits (plus a legacy diagram reference).
• Exploring the Effects of Mutation Rate on Individuals
  Investigates how single-organism responses vary when mutation rates shift.
• Exploring the Effects of Mutation Rate on Populations
  Scales that question to population-level evidence and histogram storytelling.
• Artificial Selection: Evolution in Practice
  Guides students through deliberate selection, including reporting templates that mirror the legacy PDF advice.
• Exploring Selection and Fitness
  Focuses on selection gradients, fitness landscapes, and interpreting plots.
• Experimental Evolution Project with Evolving Digital Organisms
  The capstone project that unites lab manual practice, reporting, and open-ended research; still references the original lab-book and workspace download for pacing cues.

Version note​

Some of these lessons originated in earlier Avida-ED versions. They remain usable, but instructors should expect occasional differences in screenshots, labels, and interface details compared with the current application. When that happens, the lesson goal matters more than exact interface matching.
