Before you just go grabbing Google, think again. Google searching leaves a trail that may let advertisers, the government, and who knows who else know where you have been. You can read about Google and privacy by searching the library web page. You can also enjoy privacy enhanced Google searching with Startpage.com, Qwant, or Duck Duck Go. You can read more about privacy enhanced searching at The Search Engine and Directory Snapshot.
General Meta Sites cover a wide variety of subjects and are mainly for the general public, though they often contain a lot of both newsworthy and scholarly material. Many have live editors that screen out obvious "clunkers" such as term paper mills and quack physicians selling useless nostrums.
Curlie: Curlie is short for collection of URLs, and uses live editors to add sites to a variety of subject categories. Curlie includes a Kids and Teens category and endless Regional categories to help those planning trips. The Science and Radio listings are also especially helpful. The site is no longer searchable, but the search engine will return eventually.
Dotdash -- Merididth: Dotdash--Meridith offers online versions of a variety of lifestyle, money, and consumer technology magazines, the kind you might find in a drug store or supermarket. Dotdash is especially good for consumer health, recreation, and lifestyle topics.
ThoughtCo used to be part of >Dotdash, but which now stands alone, offers articles about study skills, and consumer information on education. Most of the articles are at least two years old.
Dummies: Dummies' slogan is "Learning made easy," and this site's publisher is Wiley, which publishes the famous for Dummies series. The site features current and credible articles and videos on how to do just about anything.

Note: the articles you find on Google Scholar are usually locked behind paywalls due to copyright restrictions.
