Hi,
The hardest part is getting you head around the presenting work in front of others :)
Briefly explain the case you are doing, such as the Soham murders.
As its only 10 mins remember to make it as an outline but keep notes for if you have questions at the end.
Find out the outcomes - so for the Soham case CRB checks were not done regularly and for every setting. The Climbie case it was lack of communication and partnership working between settings that she was under.
The impact on what the cases had - so it is now law that you cannot work at a multiple settings with only one CRB check because of the Soham case. And obviously the Laming report resulted in the Every Child Matters agenda that every setting working with CYP follow. Think about the policies and procedures set up to abide by the five outcomes of ECM. This has had a major impact on the way settings care for children.
Finally you could possibly get quotes for your presentation, with reference, to back up the importance of the changes made after these cases. This way it will help link in to a conclusion.
Hope this helps
Oh and i'm sure once you've done it you will be wondering why you was worried to begin with :)
