How can I delete my online presence?

If I were to google "my name + my college name" or "my name + my high school name," so much information pop up because I was a part of many clubs and sports. There are posts, pictures, and records anyone can easily access. (i.e. a Facebook post from a club I was in with pictures of me, my high school sports records, an article about a scholarship I received etc.)

Is there a way to not make them show …
