Answer:
Use a Search Engine, or ask your teacher for suggestions.
Explanation: If you want to find a blog, looking up something in a format similar to this {Blogs about [Topic of interest]}. Typically, a good search engine will locate you plenty of blogs of that topic, and it is up to you to vet them, or combine it with asking on a forum. (Hope this helps) Note: For teachers, it depends on how invested they are into the subject they teach. If you have a teacher who pours their life and soul into their work, ask them. Just point blank ask them for the best blogs about the topic. They will do their absolute best to make sure that you are reading a trusted blog for information. On the other hand, if they really don't care, and do it for the pay, searching it up is the better idea.
