describe one difference and one similarity between science and pseudoscience

 A scientific experiment is repeatable. Pseudoscience makes claims that cannot be either confirmed or denied. Both seem to want to explain our experiences and broaden our understanding. 

Science, as a working method, employs basic principles such as objectivity and accuracy to establish a finding. It often also uses certain admitted assumptions about reality, assumptions that must eventually support themselves and be proven, or the resulting finding fails verification. 

Pseudoscience, however, uses invented modes of analysis which it pretends or professes meet the requirements of scientific method, but which in fact violate its essential attributes. Many obvious examples of pseudoscience are easy to identify, but the more subtle and therefore more insidious and convincing cases.
