Making Decisions



Carriers of a inherited condition have to make many difficumaking decisionslt decisions including what to do if they want children. In this activity students are placed in the role of a couple who are carriers of beta thalassaemia major. They are guided through how to make a difficult ethical decision and are introduced to IVF and the technology of pre-implantation genetic diagnosis.

Learning objectives

  • Explain how IVF with PGD can be used to help a couple with an inherited condition to have a healthy child.
  • Recognise ethical, social and economic arguments and use them to make an informed choice.

England National Curriculum KS3:

  • Working Scientifically: Make decisions based on the evaluation of evidence and arguments.
  • Biology: Inheritance, chromosomes, DNA and genes: heredity as the process by which genetic information is transmitted from one generation to the next.     Reproduction: reproduction in humans (as an example of a mammal), including…gametes, fertilisation.

GCSE Combined Science subject content:

  • Working Scientifically:  Development of scientific thinking: explain everyday and technological applications of science; evaluate associated personal, social, economic and environmental implications; and make decisions based on the evaluation of evidence and arguments.
  • Biology: Inheritance: explain single gene inheritance, predict the results of single gene crosses.

    Worked well as the Big Picture Lesson

    Thank you so much. I have used this activity with my Year 11 class as an introduction to inheritance unit, worked really well with students. I am now laying out the videos on my personal website to facilitate students exploring in small groups on laptops. I will be teaching my Year 10 the new AQA Reproduction unit next. I am planning to use this activity as the main story to pull all the concepts together.
    Here’s the sequence if anyone want to use it or http://www.edinthecloud.org/b16-inheritance.html
    Lesson 1 Making decision
    Lesson 2 Reproduction
    Lesson 3 Meiosis
    Lesson 4 DNA
    Lesson 5 Protein synthesis
    Lesson 6 Inheriting traits
    Lesson 7 Sex chromosomes
    Lesson 8 Inheriting disorders

    Making decisions

    Interest was high but i hoped for a bit more genetics and a lot less ethics!

    Engaging but sound too low

    The resources were all very engaging and the problems were well explained. However, the students struggled to hear the sound in most of the videos as it was very quiet!
