The thing that I never realized was that apples have an almost unlimited amount of juice in them.
I also learned that you cannot dissect an apple in just any spot on the apple. you have to go in some specific spots that are very hard to find (not really).
I was surprised about the amount of juice that the apple had. It makes me wonder how the scientists take the juice out of the apple.
I think that observing and describing is important to science because scientists these days want to know every little detail so they can make an impression to other scientists.
