It's either inquisitive learning or inquiry-based learning (with a hyphen). Making a mistake on your very subject in the first sentence of your essay will make it seem like you can't proofread. Also, your first three sentences start with very similar words, which makes them sound repetitive. You might want to rephrase them.
This sounds naive to me. Of course you're going to find knowledge if you're digging into a pool of knowledge. Also, digging in a pool...? You may want to find another analogy. Also, don't forget the apostrophe in "it's".
This looks dragged out. You're saying that inquiry-based learning increases one's knowledge and therefore one's satisfaction, happiness and power, but you use "mind" and "power" twice, as well as a rather useless subordinate clause.
I reckon this capital letter is unnecessary. Also, "driven", not "drived".
It's hard to give an overall opinion without any context. Are you an 8th grader, a 10th grader, an undergrad college student? Is English your native language? Which class is this for?
