There are some good anime that you can enjoy at the same time learn a few things. (Wow, serious) This season there are a few, but three I will put here.
Want to learn about camping, watch "Yuru Camp." The 2nd season started yesterday. It is a good one. It's about girls and the fact that they like to camp. They camp all over Japan. You learn while you watch this series.
Cells at Work: I didn't complete the 1st season. It wasn't my type of anime to watch. Though if you want to learn about the human body and blood cells, then watch this. It might even help you past a test.
Cells at Work: Code Black: I am not watching this either, yet I am pretty sure it is the same as CaW.
