IGCSE Biology Podcast: Air pollution

This podcast covers air pollution by carbon dioxide and methane (the greenhouse gases) and sulfur dioxide and nitrogen oxides, which cause global warming.

I have slightly over-edited it so a couple of words are truncated. So where it says “contributor are”, I really mean “contributers are”. Also I am saying “acidified lakes” not “lake” and “birth defects” not “bird defects” (which is what I think it sounds like). I know I should change it but honestly I already sound like three different people on it I have corrected it so often.

Anyway the information is what is important, enjoy!

IGCSE Biology Podcast: Agriculture and soil erosion

This is my first try at a podcast. It relates to the Human Influences on the environment section of the Cambridge IGCSE Biology course. It focuses on the impact of modern technology in agriculture, how this varies between developing and developed countries. It also discusses the causes and effects of soil erosion and how it can be prevented. It is about 4 minutes long. The beginning is a little quiet but I get into my swing towards the end, though still clearly nervous. Hopefully I will get better with my other podcasts!

GCSE Science podcasts for revision and general listening

My daughter got an iPod Touch for Christmas and I have to say I now want one my self. All of her friends have also received ipods and this has made me think about doing some podcasting for downloading onto ipods, as well as the videos I am developing. I am not alone in considering podcasts for my students as this is also a topic in the TES Science forums. I have come across some excellent audio files via the trusty GCSE Bitesize website and, although they do not match exactly with IGCSE, are an excellent resource. Biology, Chemistry and Physics collections are available and they are well presented. They are run by a group lnown as The Naked Scientists and there are further excellent podcasts available from their own website and may be useful for A level students also. Both links are available below (and are also available on my Links page).
