Bleurgh, just come here to say that Book 2 of Exploring science has reminded me how much I hate rocks. I am definitely never going to be a geologist. I remember that at school the only good bit about doing earthquakes was getting to go on the Kosovo earthquake simulator at the Natural History Museum over and over again! And I only did that because the school wouldn't let us look in any of the rest of the museum! Anyway, rant over. I'm coming up to chapter 11 now which I think is more spacey stuff so hopefully that won't be as tedious!
