Unraveling Genetic Mysteries

Grade 7MathScience20 days
The 'Unraveling Genetic Mysteries' project for 7th-grade students integrates math and science to explore genetics. Through activities like simulating genetic trait inheritance using Punnett squares, researching genetic diseases, and engaging in ethical debates, students gain a comprehensive understanding of Mendelian genetics, genetic disorders, and associated ethical issues. The project develops students' ability to analyze genetic conditions and predict trait inheritance using probability, fostering both scientific literacy and ethical awareness.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we use probability to predict the inheritance of traits and analyze the diagnosis, treatment, and ethical implications of genetic diseases?

Essential Questions

Supporting questions that break down major concepts.
  • How are traits passed from parents to offspring?
  • How can probability be used to predict the likelihood of inheriting certain traits?
  • What are the different types of genetic diseases?
  • How can genetic diseases be diagnosed and treated?
  • What are the ethical considerations surrounding genetic testing and gene therapy?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Students will be able to explain the basic principles of Mendelian genetics, including dominant and recessive alleles, and use Punnett squares to predict the probability of inheriting specific traits.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

Punnett Square Predictor

Students will explore the world of genetics by simulating trait inheritance using Punnett squares. They will select traits, determine genotypes of parents, and predict the probability of offspring inheriting specific traits.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Choose two traits you want to study (e.g., eye color, hair color).
2. Assign genotypes to the parents based on dominant and recessive alleles for each trait.
3. Construct a Punnett square for each trait, combining the parental alleles to determine the possible genotypes of the offspring.
4. Calculate the probability of each genotype and phenotype for the offspring. Express the probabilities as percentages.
5. Write a summary explaining your findings, including the predicted probabilities of each trait appearing in the offspring.

Final Product

What students will submit as the final product of the activityA completed Punnett square for chosen traits, along with a written explanation of the predicted probabilities.

Activity 3

Ethics of Genetics Debater

Students will explore the ethical dilemmas surrounding genetic testing and therapy through a role-playing debate.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Divide into groups representing different stakeholders in the debate (e.g., patients, doctors, ethicists, policymakers).
2. Research and prepare arguments for your assigned stakeholder perspective on a specific ethical dilemma related to genetic testing or gene therapy.
3. Participate in a class debate, presenting your arguments and responding to opposing viewpoints.
4. Reflect on the debate and write a summary of the key arguments presented, along with your personal perspective on the ethical considerations.

Final Product

What students will submit as the final product of the activityA written reflection on the ethical debate, including arguments for and against specific genetic advancements.

Alignment
