A couple of sites when looking at Ethics and research are:

3 of my favourite psychology websites are:
1. http://www.thinkib.net/psychology - a really useful resource to help teach the course. There is free material available...but it is well worth paying the annual subscription to have unlimited access.
2. www.pearsonbacconline.com - useful material and resources to supplement Law et al's textbook - 'Psychology'
3. http://www.psychologyconcepts.com/ - this has lots of resources including videos etc
