Some basic ideas about GENETIC ENGINEERING and some related ethical and social concerns.


Introduction

We select the topic of Genetic Engineering because it is a current issue which appears in the media very often and sometimes it is not very well understood even for those who talk about it publicly.
The aim is to clarify some basic concepts and to make our students reflect on the matter.

Another important goal of this activity is to stimulate students to use English:

  • to explore the internet and to read some information on the selected scientific issue

  • to practice listening and speaking while working in groups and presenting their reports in front of the class

  • to develop or improve writing and ITC abilities while working on the group presentation or report.


This work is prepared for learners who study Biology and Geology 4º ESO partially in English. The topic is related to the Part 2 of the subject (Life evolution), included in the Unit 2: Genetic Information. It is such a hot debate issue that concerns everyone in society and, because of that, it would most likely stimulate learners’ motivation.
The whole activity would take about 4 sessions.
Task and process:

What do you know about GMOs? Why are the scientists so excited about Genetic Engineering? Whom will the technology help? What does this mean for me and for people in general? Why are some ethicists and ecologists so worried about Genetic Engineering? Does it have the potential to hurt anyone or anything? Why or why not should scientist go further in their researching on Genetic Engineering? Who will decide it? How?
This task will help you to explore, understand and criticize what genetic engineering means and its effects on our health, environment, etc.
You have to choose one of the topics and find other classmates interested in the same matter. Then you can use the web sites below as a starting point for your previous homework consisting of gathering some information about the item. After that you have to share and discuss your information with your group partners and summarize the main ideas in order to make your report or presentation. Remember to write down the main web sites you took your information from (2 lessons). Finally you have to explain your presentation in front of the class and listening to other groups’ reports (2 more lessons)
As an additional ITC task each group has to look on the Internet for an interview, a current piece of news or information about Aragonese scientists or researching groups in GE, GMOs, etc. You might want to follow the suggested links given on the section Actividades complementarias con TIC links at the end of this paper to carry out your task. Each team should write a brief summary about the selected item that might help you to improve your final mark.
Suggested points for further investigation, some related questions and pages to carry out each group task:


  • Introduction to basic Techniques

  • Find three different ways in which genetic engineering is used. Explain at list two examples including the general method used in each case.

  • Genetically modified foods or organisms

Some questions to focus on:

  • What are GE foods?

  • Are genetically engineered food or organisms safe? Are they necessary? Are they destroying our environment?

  • What do we need to know about genetically engineered food as consumers?

  • Should genetically engineered food be labelled and why?
