True science looks at all available data, makes theories, and tests them. Adjustments are made when the theory does not fit the science. Our understanding of the universe is an example of this.
Pseudoscience is where determinations of what we want or desire is made and we take available information to prove this conclusion. Man induced Global Warming is an example on this.
Science is a systematic method of acquiring information. It depends on the idea that the natural world works according to certain principles, and that we can discover those principles through observation and experimentation.
Pseudo-science is the opposite of science, it is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
Hope this helps! Let me know if you need anymore help :D
