“Eating bacon sandwiches is bad for you!”: evaluating risk
Posted on May 17, 2013 by Liv Chapman
Name of resource:
Evaluating risk: are bacon sandwiches bad for you? 
What is the resource about?
The resource is about how to work out the risk of eating bacon sandwiches everyday.
Who is it aimed at?
It’s aimed at 11 – 16 year olds but I personally think it should be aimed more at 13 – 16 year olds, as it was quite hard.
How long might it take to finish?
I think it will take quite a long time, especially if you find percentages hard. Just to do the first worksheet and watch the first two videos, took nearly an hour.
What I think of it:
I think it’s quite good, as I understand that the risk increases by 20%, but i’m not really sure why. I think it could be better by explaining, why and how it increases the risk. I liked the first videos because they were quite clear and to the point however, I couldn’t get one of his presentations to work, and maybe that’s why I found it difficult and didn’t really understand it. I found the third video a bit confusing, as it seemed to have nothing to do with the bacon sandwiches theme, so I felt none the wiser for having watched that video.
