Does this sentence make sense?

Science is an intellectual activity carried on by humans that is designed to discover information about the natural world in which humans live and to discover the ways in which this information can be organized into meaningful patterns. A primary aim of science is to collect facts (data). An ultimate purpose of science is to discern the order that exists between and amongst the various facts.

Perhaps your sentence should start with the subject: "Science is involved in everything around us, whether it's about the planets in space or the fish in the ocean."

I like this one better

'Science is required to understand everything from the planets in space to the fish in the ocean'

the plural of fish is fish, just like the plural of moose is moose

example: I have one fish, but my friend has three fish.

The sentence does not answer the question of " What is science "

Well, to me it does. Except it's "fish" not "fishes" as pointed out before. It really depends on what level you are on. Good luck xxx

They aren't asking you for a correct answer but for your point of view from the sentence and how you want to answer it.

Nope. It's not looking for what science is INVOLVED in.

for me i think it makes sense... i think what it is trying to say is that science is everywhere and everything is related to science.

I suppose so, but I think they're looking for a direct definition. It needs commas and "-" before whether.

The topic name should read "What is science?" - do not forget the question mark!

Possibly: "...science involved with everything....", or possibly: "Science is involved in everything.....". My second version feels more "direct", more "involving". Note the different uses of "with" and "in".

Probably "fish" rather than "fishes". "Fish" is a word with two plural forms, generally "fish" is the more commonly used plural form.
