Science uses a logical approach to answer questions and solve problems. It uses systematic observations and experiments that can be reproduced, and develops laws and theories that can be tested and verified. In contrast, pseudoscience is not supported by scientific evidence. It’s a system of assertions about the natural world that claim to be scientific but, in fact, are not.

In this assignment, you will examine examples of both science and pseudoscience. Please answer the following questions in your own words (Turnitin score less than 30%).
