Lesson Plan: The Digital Geneticist's Field Guide

Materials Needed:

• A computer with internet access
• Access to the game Geniventure (free, web-based)
• Access to the game Wobbledogs (requires purchase)
• A digital document (like Google Docs) or a physical notebook for a "Genetics Lab Notebook"
• Optional: Art supplies (digital or physical) for the final project

Learning Objectives:

By the end of this lesson, you will be able to:

• Apply the principles of Mendelian genetics (alleles, genotype, phenotype, dominant/recessive traits) to predict the outcomes of breeding virtual organisms.
• Design and conduct a selective breeding experiment to achieve a specific goal within a virtual ecosystem (Wobbledogs).
• Analyze and compare the genetic models presented in two different games, evaluating their scientific accuracy and creative liberties.
• Synthesize your learning by creating a "Field Guide" entry for a unique creature you have bred, using correct scientific terminology.

Curriculum Alignment (Example: NGSS):

• HS-LS3-2: Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.

Lesson Activities

Part 1: The Geneticist's Training Ground (45-60 minutes)

In this part, we'll use Geniventure to build a solid foundation in core genetics concepts. It’s like being a dragon-breeding apprentice!

1. Introduction (5 mins): Watch this short video on the basics of heredity: "Heredity: Crash Course Biology #9". In your Lab Notebook, define the following terms in your own words: Gene, Allele, Genotype, Phenotype, Dominant, Recessive.
2. Guided Practice - Geniventure (30-45 mins):
   • Go to the Geniventure website and start playing. Your goal is to complete the first two "Journeys" (introductory levels).
   • As you play, pay close attention to how the game represents alleles (the letters like "T" and "t").
   • Lab Notebook Task: In Journey 1, Case 5, you are asked to match the correct genotype to the drake's phenotype (appearance). Before you solve it in the game, write down your prediction in your notebook and explain why you chose that combination of alleles. Did the game match your prediction?
   • Complete up to Journey 2, Case 6, where you use Punnett squares to predict outcomes. This is a key tool for geneticists!
3. Check for Understanding (10 mins): In your Lab Notebook, answer this question: "If a drake has the genotype Hh for horns, and the big 'H' allele is dominant for having horns, what will the drake's phenotype be? What would the genotype be for a drake with no horns?"

Part 2: The Wobbledog Breeding Program (60-90 minutes)

Now you're ready to move from a structured lab to field research! In Wobbledogs, the genetics are more complex and unpredictable, just like in the real world. You are now the head researcher of your own breeding program.

1. Set Your Research Goal (5 mins): Open Wobbledogs. Look at your current dogs. Choose one specific physical trait you want to breed for. Your goal should be specific. For example:
   • "To breed a dog with the longest possible legs."
   • "To breed a dog with blue body color and wings."
   • "To breed a dog with the fewest possible legs (e.g., one or two)."
   Write your research goal at the top of a new page in your Lab Notebook.
2. Conduct the Experiment (45-75 mins):
   • Begin breeding your Wobbledogs with your goal in mind. Select parent dogs that have characteristics closest to your desired trait.
   • Data Collection is Crucial! For each new generation of dog, document the following in your Lab Notebook:
     • Parents: Which two dogs did you breed? (Take a screenshot or describe them).
     • Offspring: What did the new pup/dog look like? (Take a screenshot).
     • Analysis: Did the offspring get closer to or further from your goal? Which traits from the parents did it inherit? Were there any new, unexpected traits (mutations)?
   • Continue this process for at least 3-4 generations. It's okay if you don't fully reach your goal; the process is what matters!
3. Analyze Your Findings (10 mins): Look back at your notes. Answer these questions in your Lab Notebook: "Was it easy to breed for your chosen trait? Why or why not? How is breeding in Wobbledogs different from the clear dominant/recessive rules in Geniventure? What role do you think the food and environment played in your dogs' mutations?"

Part 3: The Digital Geneticist's Field Guide (45-60 minutes)

This is your final project. You will synthesize everything you've learned by creating a one-page "Field Guide" entry for the most interesting Wobbledog you bred during your experiment (this could be the one closest to your goal, or the weirdest one!).

Your field guide page must include:

• Species Name: Give it a creative, scientific-sounding name (e.g., Canis instabilis longus).
• Illustration: A drawing, sketch, or a clean screenshot of your dog.
• Phenotype Description: A detailed description of its physical characteristics (color, legs, wings, tail, face, etc.).
• Genetic History / Breeding Notes: Briefly describe the breeding process. Which "parent" dogs did it come from? Mention which key traits you were trying to select for.
• Hypothesized Genotype: This is where you get creative! Based on its parents and its appearance, invent some plausible genotypes for its main traits. For example: "Leg length appears to be a complex trait, but this specimen likely carries dominant alleles for length (LL or Ll). Body color is blue (bb), a recessive trait that only appeared after two generations."
• Behavioral Notes: A creative description of how your Wobbledog behaves in its environment.

Extension & Deeper Thinking (Optional)

• Real-World Connection: Research the selective breeding of a real animal or plant, like the domestic dog (from wolves), corn (from teosinte), or different types of brassica (broccoli, cauliflower, kale). How does that real-world process compare to what you did in Wobbledogs?
• Ethical Discussion: Selective breeding can sometimes lead to health problems in animals (e.g., breathing issues in pugs). What are some of the ethical responsibilities a scientist or breeder has?
