Science is a way of understanding and explaining the world around us. But it can also be criticized by people who don't agree with the results of scientific studies or think that the methods used are wrong. For example, some people might disagree with a scientific discovery that tells us we need to be careful about how much energy we use, or how we grow our food. The criticism of science can be seen as a positive thing, because it helps us to make sure that the scientific findings we believe are correct and useful.
