Designed originally for OCR 21st century biology unit B1.The first worksheet is designed to cover the two genetic testing (screening) techniques, amniocentesis and PGD. The second sheet covers some of the issues surrounding genetic tests. Show the YouTube video first on amniocentesis: discuss it. Then the second one from Fox News. An optional video on IVF is also included. Ethical issues can and should be raised and discussed with all videos. With the ethics sheet words could be removed for top sets or spoiler words added. It could also be altered to make it a cut and paste exercise.
