SSR Magazine

I had to read 3 articles from this magazine. My favourite one was called How Do Scientists Tell The Age Of Fish? They can tell how old a fish is by looking at the little bone in a fish's ear. The bone grows when the fish grows. The bone has rings on it because a thin layer of bone is added everyday. They said because the daily rings can become really blurry so they look for the layers of thick summer rings and thin winter rings.
