“Eating bacon sandwiches is bad for you!”: evaluating risk
Posted on 17th May 2013 by Liv Chapman
Name of resource:
Evaluating risk: are bacon sandwiches bad for you? [1]
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.
