Applying genetic knowledge in prenatal and predictive genetic testing pre-task


This activity prepares students for their visit to GTAC for the Applying genetic knowledge in prenatal and predictive genetic testing program. It consists of two parts:

Flipped classroom

Prior to the lesson, students are expected to watch the following short video which introduces them to the key concepts of Meiosis: https://www.youtube.com/watch?v=-DLGfd-Wpr4. Click here to download a worksheet that accompanies this task. Alternatively, teachers may choose to play this video to their class at the beginning of the lesson.

 

Modelling task in class

For this activity you will need the following materials:

  • Scissors (1 per student)
  • Sticky tape
  • Blue-tack (optional)

You will also need the following files (click to download):

In this activity students learn about the key stages in meiosis using interactive models and class discussion.  They investigate how gamete formation generates genetic diversity through chromatid crossing over and random assortment. Below is a downloadable Power-point that goes through, step by step, how to complete the meiosis modelling task, including discussion questions and sample answers.

Throughout the activity, students will take photos of their models after each phase of meiosis. These photos will then be used to complete the Meiosis summary sheet which encourages students to reflect and describe their learnings from the activity (answer sheet available on request, let us know via admin@gtac.edu.au). They can complete the summary sheet either digitally or print a physical copy that can be pasted into their logbooks for future reference.
