the easiest thing to do in science is……just be curious! Science is just a set of guides to help us understand the physical universe around us, there is nothing really special to it. The most important thing is for the scientists like you to be curious! I’m not very clever or special, I am just really really nosey about the world and want to know how everything works.
Next easiest thing is geology, we just look at rocks and then read them like story books, it’s a lot of fun! 😀
I’m with Sam on this one: I think it’s quite easy thinking of an experiment that nobody’s done before. However, it’s much harder to find out whether or not that’s because it’s not a very interesting experiment to be doing/question to be asking.
